3ders.org – colorFabb_HT filament revealed, good for sturdy and temperature resistant 3D prints

March 1, 2016 | From Alec

The web is full of amazing and inspiring 3D printing projects that illustrate just how big the hobby has become. The only disadvantage is that the tried and tested ABS and PLA filaments are not always suitable for research projects and practical prototyping. While the results usually look good, they don’t always have the right toughness or strength to do what they need to be done. In this case, it is best to try less conventional filaments. The renowned Dutch filament supplier colorFabb has just presented the latest edition of its excellent range: colorFabb_HT, a clean material that is perfect for practical 3D printing solutions due to its high strength, superior durability and stability, toughness and excellent temperature resistance.

The Dutch manufacturer colorFabb is of course known for its excellent 3D printing accessories. Founded a few years ago as a subsidiary of Helian Polymers, a sister company of Peter Holland, they quickly became a supplier of a range of excellent and sometimes unusual filaments.

While some of their other materials are largely attractive for aesthetic reasons, their excellent properties are colorFabb_HT’s main selling point. It is made from Eastmans Amphora ™ HT5300 3D polymer, which is styrene and BPA free, has little odor and is particularly suitable for parts that are exposed to unusual circumstances. It also has an advanced overhang capability which makes it perfect for practical parts. “HT5300 has excellent dimensional stability and enables 3D printing with precise dimensions. This is especially important for products with tight tolerances and multi-component parts. In addition, with its excellent toughness and chemical resistance, Amphora HT5300 is ideal for prototyping and testing products, ”the manufacturers are proud to say. The impressive drill holder (see above) really says it all when it comes to durability.

Perhaps most impressive is the high level of heat resistance, as 3D-printed colorFabb_HT parts can withstand heat of up to 100 degrees Celsius. “This means that your co-polyester creations can finally withstand heat without deforming. This opens up new areas where 3D printing applications can be successfully applied, ”it says. This is illustrated using 3D printed parts from toy engines made by a user named Dennis. “By using colorFabb_HT, Dennis can experiment with specially shaped intake manifolds to improve the performance of this mini rail vehicle. The fact that he can now test these parts on a running engine means a lot in his design process, ”it says.

Latest cool colorFabb print: The gCreate Rocket Ship (Thingiverse), made of copper filling, bronze filling, brass filling and glow filling.

If you’re interested in this excellent filament, it will go on sale in three weeks, March 21st – both through yours Webshop and their international resellers. Pre-orders for colorFabb_HT start before this time. The functional filament will be available in five colors: clear, white, light gray, dark gray and black. You can catch colorFabb at RapidPro 2016 this week too. At the congress in Eindhoven, the Netherlands, they will be showcasing a wide variety of their filaments so that you can check the results in person.

3ders.org – Polymaker unveils PC-Max, their strongest 3D printing filament for load-bearing components

May 16, 2016 | From Alec

It must be a very busy time at Polymaker headquarters in Shanghai. Your crowdfunding campaign for the Polysher / Polysmooth layer removal kit is still ongoing (having raised more than $ 300,000), but they were also working on another major version of filament for 3D printers at the same time. Referred to as PC-Max, it is the toughest, strongest 3D printable filament ever – perfect for practical 3D printing projects, technical research, and structural components. They have added three new color options to their PolyPlus and PolyMax filaments.

Polymaker of course already has a wide range of excellent high-strength and impact-resistant filaments. So far was her strongest option PC plus, a popular polycarbonate filament with excellent material properties. PC-Max is essentially an updated version of PC-Plus designed specifically for mechanical engineering. It’s been in development for more than a year.

And like its predecessor, PC-Max was developed in collaboration with Covestro, formerly Bayer Material Science. Covestro supplied the high quality raw polycarbonate resins and worked closely with the Polymaker team to improve the filament formulation. “Covestro’s expertise, product portfolio and industry leadership will be invaluable to our mission to provide the industry with the best materials with the performance, reliability and safety that inspire our customers and expand our product portfolio,” said Dr. Xiaofan Luo, CEO of Polymaker.

What is special about PC-Max? In short, it has mechanical properties that you rarely see in 3D printing materials and is far stronger and more impact resistant than any other Polymaker material. “Polycarbonate has properties that make it very desirable to the entire 3D printing community, and PC-Max ™ makes it even better for creative designers and engineers at every stage of the production process,” added Dr. Luo added. PC-Max is also easier to 3D print than PC-Plus, which was 3D printed at 300 ° C – 320 ° C. In contrast, PC-Max can be 3D printed at a moderate 250 ° C – 270 ° C.

Most importantly, PC-Max is extremely strong and brings all of these mechanical properties to desktop 3D printing. According to Polymaker, all tests showed that parts made with PC-Max performed much better than other PC components in numerous deformation modes. While high heat filaments can be plagued by warping, Polymaker has also reduced the likelihood of this happening by minimizing the residual tension on the filament. In addition, the filament can easily be sanded, coated and subjected to other post-printing processes. PC-Max withstands temperatures well over 110 ° C, is flame-retardant and resistant to chemicals and solvents – perfect for technical environments. If you are interested, the filament will be available in the Polymaker website this month and costs $ 39.99 per roll.

Coincidentally, the busy Polymaker team has just added three new colors to its PolyPlus ™ and PolyMax ™ filament range: True Green, True Gray and True Purple. This brings the full numbers to 11 true colors and 4 translucent options for PolyPlus and 10 true colors for PolyMax. The deep green and purple options should provide a perfect aesthetic effect, while the real gray option should be very appealing to the busy technical user.

3ders.org -Portuguese engineer 3D prints beautiful rotating DNA Helix Lamp utilizing glow-in-the-dark filament

June 10, 2015 | From Alec

While there are dozens of fun and unusual filaments out there to add some spice to your 3D printing projects, the vast majority of us still stick with boring old PLA or ABS. While I’m not in favor of a boycott, it’s just good to know what can be done if a little variety is added. Why not have fun with PLA filaments in the dark, for example, as the Portuguese engineer João Duarte did? He used it to create a very inspiring lava lamp-like creation that consists of an absolutely inspirational rotating and glowing in the dark DNA helix lamp.

As João 3ders.org explains, he is a young electrical and electronics engineer from Algarve, Portugal who absolutely loves technology. ‘I am a member and also one of the founders of eLab Hackerspace in Faro. I recently entered the world of 3D printing building my own Prusa i3 and so far I’ve learned a lot and developed myself further, ”he says. He also holds one personal blog of his fun 3D printed creations, but its DNA Helix lamp absolutely takes the cake.

As he explains, this lamp was inspired by the traditional lava lamps we all had in the nineties, but João wanted to turn them a little differently and PLA in the dark was a perfect solution. “I was looking for 3D objects online to test my 3D printer when I found some strands of DNA. They looked cool so I tried looking at them from different angles and I found that while rotating the piece they created an amazing and mesmerizing effect up and down. So I thought about designing a lamp that was also a bit inspired by the lava lamps, ”he says. I thought about using glow in the dark filaments to highlight the DNA helix when the lights were off. I also thought it would be cool to fade the LEDs on and off for a cool visual effect on the DNA. They go from bright white to green, giving her the strange feeling of a mysterious nasty experience or that she is somehow alive. ‘

Well, this would be a challenging project even for the best of us, but João had only just started the 3D printing hobby. “So I didn’t have a lot of experience with 3D design, but I also wanted to get this project done quickly because I noticed that there was a teaching competition on 3D printing and I wanted to take part,” he says. With that in mind, he relied entirely on Autodesk’s Tinkercad web app for the design, which is simple and intuitive to use but doesn’t reflect the end result of this project at all. It just shows how much can be done with a little creativity.

And we have some great news for those of you looking to recreate this amazing project, as João wrote a very detailed Instructables tutorial. But be careful: it’s a fairly complex setup with lots of electronics and dozens of parts, so it may not be suitable for the beginner. As he explains, the entire structure essentially revolves around an electric motor that supports and rotates the DNA helix in an acrylic tube. ‘It has LEDs on the top and bottom of the tube that create a fading effect. Then it has a microcontroller (Arduino) that controls the rotation of the motor and the LEDs. I also added a push button on the front of the lamp that allows the user to switch between different modes of operation of the lamp, e.g. B. turn the rotary motor on or off and let the LEDs fade or always leave it at full brightness or completely off, says João. If you want to do this yourself, you can You can find the tutorial here.

However, you will find that the 3D printing phase of the project is quite straightforward. It took João about seven hours to design all of the pieces, even though he made all of his designs available for us to copy. He relied on his homemade Prusa I3 3D printer and a LulzBot TAZ 4 in his local hackerspace and 3D printed most of the parts in the black PLA that he had lying around, which, by the way, works great in combination with glow-in-the-dark filament. “For the DNA helix, I wanted to have a strange effect when the LEDs were turned off. So I thought it would be very cool to use the PLA filament“ Glow in the Dark ”. This is why it glows green when there is no light is. ” 3D printing took about 14 hours with two printers running at the same time. The print settings were pretty simple for an average quality with 20% fill, 0.2 mm layer height and a speed of 50 to 70 mm / s.

Now most of these parts are relatively easy to 3D print, although the DNA helix deserves special attention as the centerpiece: “It’s probably the hardest part because it’s very fragile, has many bridges, and requires a lot of retreats during the printing process. I designed it with 4 vertical support columns (already in the 3D model). This part should be printed as resiliently as possible, so I increased the shell thickness and the top / bottom layers, ”says João. However, the 3D printing results are definitely satisfactory. After a nice cleaning with a scalpel and a small pair of pliers, the carrier material was gone. For the DNA strand, this must be done very carefully. Cutting the support pillars could force and break the DNA structure, so I had a lot more success by melting them with the metal head of the hot glue gun and then removing the rest with the scalpel. Because the DNA has a lot of retractions and bridges, there can be a lot of threads (as you can see in the images above), but these can also be removed with a scalpel, ”he explains.

After the easy part is done, assembly and electronics are waiting for you. This is a very complicated phase that requires dozens of parts. Most you might have lying around or can save from another project; João even took the AC motor (usually the most expensive part of a project) off the rotating platform of an old microwave. However, be sure to follow the tutorial to install it. “We will be dealing with AC mains voltage, which is extremely dangerous and must be handled with extreme care!” João rightly warns us.

However, the result is definitely worth the effort as you can see for yourself in the following clip. “But since it’s a lamp, it naturally looks much cooler in the dark, especially when the DNA helix glows in the dark. The UV LEDs make for that amazing mesmerizing blue and purple, perfect for this project! It looks exactly as I imagined, ”says João. And there is nothing we can do but be absolutely in agreement; Have you ever seen a more impressive 3D printed lamp? João is already working on his follow-up project, which is also a lamp. We will no doubt hear more from him in the near future.

3ders.org – Owa 3D: Armor turns used printer cartridges into recycled HIPS 3D printing filament

September 29, 2016 | From Tess

French company manufacturing ink cartridges armor recently moved into the 3D printing materials industry with the launch of its first filament line, Owa 3D. The new filament, which is fully recycled and made from high impact polystyrene (HIPS), is part of the cartridge manufacturer’s effort to reduce, reuse and recycle plastic waste from printer cartridges.

About a year ago, Armor launched its Owa campaign, which aimed to reduce the amount of plastic cartridge waste in the world. According to the company, 360 million printer cartridges are purchased each year in Western Europe alone, a staggering 70% of which either end up in landfills or are incinerated and not recycled. Armor developed Owa as a circular economy approach to deal with this waste and reduce it significantly. Since the program was launched, Armor has been collecting old cartridges from companies and effectively converting them to new cartridges or breaking their materials down to become new office supplies.

Now Armor seems to be branching out even further with its Owa initiative with its new 3D printing filament. If you didn’t guess it, the Owa 3D filament itself is made from plastic from recycled cartridges as well as from other sources like yogurt containers etc. As mentioned earlier, the filament is made of high impact polystyrene, also known as HIPS, which is a more flexible and durable material than other standard 3D printing materials like PLA or ABS.

Owa 3D, currently available in both France and Japan, is preparing to launch across Europe (e.g. Germany, Belgium, Spain and Italy) as well as in the UK and Switzerland. The filament is compatible with most FDM 3D printers and will be available in standard filament spools of 750 g and in two diameters (1.75 mm and 2.85 mm). In addition, the recycled HIPS filament will be available in a range of 12 different colors and can be tested by customers using “Discovery” packages made up of six 162g spools of different colors.

Also noteworthy about Armor’s Owa process is that the company has agreed to pick up recyclable used cartridges from companies in order to create further incentives for recycling their office waste. From there, the used cartridges are taken to one of Armor’s processing plants, where they are either processed into new cartridges or into 3D printing filaments. The 3D printing filaments are currently being produced in the Armor factory in Morocco and in La Chevrolière near Nantes.

No prices have yet been set for the new recycled filament, but prospects and customers can follow the countdown to the product launch on the Owa 3D website.

3ders.org – Artist creates amazingly lifelike tree sculpture utilizing 3D printing pen & wooden filament

March 5, 2018 | From Tess

There is no question about that 3D printing pens can be used to create some pretty amazing and creative things. Of Fashion to 3D images and sculptureFor years people have been pushing the artistic boundaries of the 3D pen medium. However, never before did we have to take a second look at a 3D pen sculpture to see if it wasn’t.

The artist Martin Binder has created a four-meter-long birch tree sculpture with a 3D printing pen and a wood-plastic composite filament. The piece entitled “Portrait of a Birch” can currently be seen in Berlin’s Super Bien! Contemporary art greenhouse where it is hung in a glass case.

From a distance the 3D drawn tree is scary and one could easily and falsely believe that it is a real birch branch hanging behind glass. On closer inspection, however, the precisely drawn lines of the plastic of the 3D pen become clear. Amazingly, the 3D pen’s plastic filament mimics the pattern and visual structure of an actual birch tree.

For an additional feeling of authenticity, Binder decided to work exclusively with a filament made of plastic and birch wood. He adds that he has carefully studied natural birch trees to perfectly capture their appearance. “My eyes were the 3D scanner and my hands were the 3D printer,” he says.

In total, it took Binder over 250 hours to create the tree with a 3D printer (that’s more than six weeks of full-time work!). The effort is evident in the fine details and the natural feeling of the industry.

The 3D drawn branch is displayed in a glass display case that was a conscious choice of Binder. He explains: “I spend a lot of time on Instagram where I consume pictures behind a pane of glass. This work is a three-dimensional equivalent of consuming digital media. A fragment of a tree can be visually experienced behind the glass walls of the unconventional exhibition space. “

Since the tree is on display outside, the viewer can visit it at any time of the day or night.

3ders.org – Extrudr unveils new Inexperienced TEC 3D printer filament constructed from renewable and pure supplies

March 9, 2016 | From Alec

With the 3D printing community consuming huge amounts of plastic (and how many of those prints fail?), It’s always good to use 3D printer filaments that are biodegradable or can be recycled. PLA is a good start, but is only fully biodegradable in bioreactors and under certain laboratory conditions. Grinding units are another option: machines that can be used to recycle faulty prints into new 3D printer filaments, although unfortunately these are still very expensive. Fortunately, a third option has just appeared: Extrudr Green-TEC from Austrian 3D printer filament manufacturers Extrudr. In contrast to PLA, it can be 100% broken down in natural cycles.

If you’ve never heard of Extrudr, it’s likely because they haven’t been around long. Although they have turned up here and there at some 3D printing and event events, they are actually a very young manufacturer from Austria who has been working on their products since February 2014. Although deciding on a new manufacturer can be a bit daunting since you don’t know what you’re going to get, co-founder Johannes Früh previously told 3ders.org that they have a high quality production line. “We can guarantee high quality standards such as diameter, resin, roundness, printability, etc.,” he told us.

While very young, they have already developed a diverse line of 3D printable filaments, including various brightly colored (and multicolored) PLA and ABS options, a range of PETG filaments, and some biopolymers. At the beginning of the year they also let shine in the dark, woody and pearl-like 3D printer filaments.

They are now adding Green-TEC in four colors to this line: black, blue, red and white. As they explain, it is made entirely from biological compounds and pure raw materials. “The material has a bio-organic composition and compost mixtures in contrast to PLA,” they say. “Green-TEC is therefore CO2-neutral and absolutely harmless from an ecological point of view.” It is an excellent alternative to the more conventional ABS or PLA filaments, and not just because it is environmentally friendly. It is also non-toxic and has superior temperature resistance, hardness, and elongation compared to ABS or PLA.

It is also easy to use – unlike ABS, Green-TEC 3D printer filament hardly suffers from shrinkage or warping. This makes it very suitable for larger and more complex prints with a large surface area. It doesn’t even need a heated print bed. And because it meets all EU regulations for plastics that come into contact with food, you can also use it on a wide variety of 3D printed products. While it’s slightly more expensive than other filaments at € 56 per kilo (or around $ 61), its eco-friendly properties are particularly attractive. It is also available in 1.75 and 2.85mm options.

Specifications for Green-TEC filaments:

  • Heat resistant up to 110-120 ° C, 248 Fahrenheit,
  • Low temperature of 170-200 C.
  • High mechanical resistance, which leads to lighter components
  • Very little warping (<0.5%)
  • Food safe
  • Biodegradable
  • High layer adhesion and good optical properties
  • Print parameters
  • Printed bed: 0-60 ° C.
  • Adhesion: Bluetabe, Kapton, Carbon, Glass
  • Print speed: up to 120 mm / s

Weight:

  • 1.75 mm – 2.4 g / m
  • 2.85 mm – 7.6 g / m

3ders.org – Create a 3D printed versatile LED glove with Ninjaflex and glow-in-the-dark conductive filament

August 8, 2015 | From Simon

When it comes to new and exciting things to do with the latest and greatest 3D printing materials, many projects simply involve different mindsets or assemblies of existing concepts.

To highlight what is possible with conductive filament and glow-in-the-dark ninjaflex, the famous Ruiz brothers at Adafruit recently released a new project that teaches users how to make their own custom flexible led portable – Especially a glove.

Among other things, the brothers wanted to start the project and experiment to find out how well Ninjaflex can adhere to conductive PLA filaments. The two materials already combine well and their unique properties complement each other.

The finished semi-flexible integrated circuit glove design uses a coin cell battery to power 5 Adafruit LED sequins. However, in order to create their own glove, users need to have access to a 3D printer with a twin extruder.

“We believe the concepts in this project can be used to create really cool items for cosplay props and costumes,” said the brothers.

“By incorporating conductive filament into your designs, you can create embedded circuits. The conductive filament can also be used for capacitive touch sensors! “

After sourcing the parts, which include NinjaFlex Glow-in-the-Dark Filament, ProtoPasta Conductive Filament, Bare Conductive Paint, a Lithium Coin Cell, and Adafruit LED Sequins, the design process begins with users tracing their own hand to order ensure that the finished product fits as intended.

After tracing a hand with pencil and paper, the drawing can be imported into a program that allows vector tracing, e.g. B. Adobe Illustrator. Using the traced hand image in a 1: 1 scale background image, a vector path is used to create an outline that is imported into a CAD program to create a 3D extrusion of the traced line.

Additionally, ground and power traces for each finger are created and extruded at this stage to ensure all parts and paths fit as intended. As for the coin cell case, a simple cylinder can be created and peeled in the middle of the hand (think Iron Man) – which ultimately powers the conductive strips that lead to each finger after the final glove is printed.

Once the glove and parts have been optimized for 3D printing using a twin extruder 3D printer, the hand is printed in Ninjaflex while the handprints are printed in conductive PLA filament. Because these parts are printed as a single piece, they are fused together during the printing process. The Ruiz Brothers used a Flashforge Creator Pro for their project.

Before connecting any LEDs with conductive paint, the conductor tracks are tested to make sure they can actually flow electrons by inserting the button cell into the battery holder and using a piece of copper foil tape to connect the ground, followed by connecting a bare LED to each conductive pad.

Finally, the finger straps can be added to the finished glove and tested for flexibility. At this stage, the conductive paint can fix all parts that peel off in dry places – such as B. the LEDs.

“The bare conductive paint adheres pretty well to the materials, but you can remove it with a lot of force and movement,” add the brothers.

“If you feel stressed, small touch-ups can be made. Be careful not to touch or bend yourself until the conductive paint has dried. You can also use UV / black light to amplify the light when using NinjaFlex in the dark! “

Of course, the project doesn’t just have to end with the glove – the same technique can be easily applied to any number of Cosplay or Halloween costumes.

To read the build process in full, go to Adafruit.

3ders.org – Extrudr unveils new Inexperienced TEC 3D printer filament constructed from renewable and pure supplies

March 9, 2016 | From Alec

With the 3D printing community consuming huge amounts of plastic (and how many of those prints fail?), It’s always good to use 3D printer filaments that are biodegradable or can be recycled. PLA is a good start, but is only fully biodegradable in bioreactors and under certain laboratory conditions. Grinding units are another option: machines that can be used to recycle faulty prints into new 3D printer filaments, although unfortunately these are still very expensive. Fortunately, a third option has just appeared: Extrudr Green-TEC from Austrian 3D printer filament manufacturers Extrudr. In contrast to PLA, it can be 100% broken down in natural cycles.

If you’ve never heard of Extrudr, it’s probably because they haven’t been around long. Although they have popped up here and there at some 3D printing and event events, they are actually a very young manufacturer from Austria who has been working on their products since February 2014. Although deciding on a new manufacturer can be a bit daunting since you don’t know what you’re going to get, co-founder Johannes Früh previously told 3ders.org that they have a high quality production line. “We can guarantee high quality standards such as diameter, resin, roundness, printability, etc.,” he told us.

While very young, they have already developed a diverse line of 3D printable filaments, including various brightly colored (and multicolored) PLA and ABS options, a range of PETG filaments, and some biopolymers. At the beginning of the year they also let shine in the dark, woody and pearl-like 3D printer filaments.

They are now adding Green-TEC in four colors to this line: black, blue, red and white. As they explain, it is made entirely from biological compounds and pure raw materials. “The material has a bio-organic composition and compost mixtures in contrast to PLA,” they say. “Green-TEC is therefore CO2-neutral and absolutely harmless from an ecological point of view.” It is an excellent alternative to the more conventional ABS or PLA filaments, and not just because it is environmentally friendly. It is also non-toxic and has superior temperature resistance, hardness, and elongation compared to ABS or PLA.

It is also easy to use – unlike ABS, Green-TEC 3D printer filament hardly suffers from shrinkage or warping. This makes it very suitable for larger and more complex prints with a large surface area. It doesn’t even need a heated print bed. And because it meets all EU regulations for plastics that come into contact with food, you can also use it on a wide variety of 3D printed products. While it’s slightly more expensive than other filaments at € 56 per kilo (or around $ 61), its eco-friendly properties are particularly attractive. It is also available in 1.75 and 2.85mm options.
