3DXTech Unleashes New Excessive-Modulus Carbon Fiber PETG 3D Printing Filament – 3DPrint.com

Doesn’t it seem like just a few months ago we limited ourselves to 3D printed objects in just two materials – PLA or ABS? I sure do! Just a few years ago, FFF / FDM-based desktop 3D printing seemed to have hit a roadblock while other technologies like stereolithography (SLA) seemed to take control. This was because material options were extremely limited, print speeds didn’t improve, and people were just tired of making boring plastic objects with little detail.

What a difference a few years can make. Today there are literally hundreds of different filament options available, ranging from glow-in-the-dark materials to wood and metal composites. There are even filaments that change color depending on the temperature. One of the companies that has played a pioneering role in this massive expansion of our material horizons in the 3D printing area of ​​FFF / FDM is 3DXTech. They released several unique, innovative filaments over the past year alone and today introduced another new filament – 3DXMax ™ CFR-PETG carbon fiber reinforced PETG.

3dxmaxfeatured

“In line with our goal of providing the 3DP market with high-quality, high-performance materials, we are introducing a new quality of high-modulus carbon fiber reinforced 3D printing filaments,” said Mark Haskins, 3DXTech Materials Manager, told 3DPrint.com. “Our new carbon fiber reinforced 3DXMax ™ CFR-PETG-PETG filament is made in the USA using a custom combination of Eastman PETG and high modulus carbon fiber.”

3dxmax4The filament, which is available in either 1.75mm or 2.85mm diameter, can now be pre-ordered through the 3DXTech website. It is available in 200g and 750g spools, priced at $ 26.00 and $ 58.00, respectively. The expected release date for the start of orders is June 22nd. Shipping is free on orders over $ 50 in the continental US.

“We believe carbon fiber is a transformative additive to 3D printing,” says Haskins. “It gives the compound exceptional rigidity and at the same time makes it lighter [in] Weight. Each base resin we choose brings something different to the table due to its inherent properties. In terms of PETG, it initially offers a more ductile base that allows for higher loading with CF while maintaining some ductility and impact resistance. It adheres well to a variety of build platforms and has excellent layer bonding. The carbon fiber not only provides rigidity and dimensional stability, but also has excellent aesthetic quality in the gloss it creates when printed. “

The recommended print settings for this new filament are as follows:

  • Extruder: Ideally 230 to 250 ° C; up to 270 ° C.
  • Platform temperature: 70 to 90 ° C, up to 110 ° C.
  • Platform preparation: clean the glass with Kapton tape
  • Nozzle: We currently recommend an opening of at least 0.35 mm

This new material offers superior chemical resistance compared to conventional ABS. It also ensures virtually no shrinkage during printing and moisture-absorbing properties that are three times lower than ABS. It’s also worth noting that any carbon fiber filament for a 3D printer’s nozzle is typically more abrasive than regular base plastics like PLA and ABS.

Haskins also tells us that 3DXTech will be releasing two more unannounced carbon fiber filaments before the end of the year.

New & Improved PETG: Taulman3D Releases TECH-G 3D Printing Filament with Excessive Energy, Restricted Elongation – 3DPrint.com

The world of materials for 3D printing has grown huge, as has the growing global catalog of transformative innovations that we are now gifted with. And while there are many different filaments and alternative sources to draw from, there are just as many problems, concerns, and drawbacks that are specific to each project, printer, and user.

Companies like Taulman3D specialize in helping users do something simple: create more 3D printed things – right. However, they provide us with a huge amount of information on the go, and it’s always a highlight when one of their new products shows up – which is quite common compared to other manufacturers.

oneFounded by Thomas Martzall, the filament manufacturing company consists of a team that is knowledgeable about materials and chemicals and continues to strive for new innovations and horizons for filaments, each with unique characteristics suitable for a wide variety of users looking for specific ones Elements for their own requirements.

Taulman is currently announcing the release of TECH-G, a PETG filament designed to provide even higher strength with limited elongation.

PETG filaments are becoming increasingly popular and are a modified version of the simpler PET, a non-toxic thermoplastic polymer resin used to make clothing and products such as containers. PETG filaments are an attractive and viable option because of their low melting temperature and their durability and flexibility in the finished state. PETG is a good alternative to ABS or nylon and usually offers transparency as well.

While PLA and ABS have traditionally been used, and especially by engineering firms, for “initial form and fitness assessments”, the Taulman team was aware that the overall strength of these filaments would limit the usefulness and potential of 3D models many times over.

“In the case of PLA, it was the brittleness of medium-sized or larger parts that severely restricted the functional test,” explains the Taulman team. “With ABS, the limit has always been tensile strength.”

TECH-G technical data for 3D printing:

  • Tensile Strength – 5,900+ PSI
  • Elongation – 3%
  • IZOD notch – 2.14 ft-lbf / in
  • Color – clear (colorless without added coloring)
  • Odors – none
  • Transmission – 90%
  • Printing temperature – 235 ° C – 240 ° C.

qENKNrMeDVBfed-H3_vtBFJ_yPJk5NUjVW2eY9vHlWoTECH-G is a clear, odorless virgin polymer found in standard 1kg spools. It is available in both 1.75mm and 2.85mm sizes. In fact, almost as transparent as T-glass we reported on earlier in the year, this is a material known as co-polyester. The Taulman team suggests several tips for using with TECH-G, such as:

  • Users should use lower fans when printing PLA polymers
  • The best printing surface for a glass finish is printing on heated glass at 72 ° C.
  • For a quick release bed, users should wipe a glass heated to 45 ° C with 50% PVA and 50% water
  • Print temperatures vary slightly with nozzle size, but the average is 238 ° C.
  • If too much is printed at too high a temperature, bubbles will appear in the printed thread, and if too cold the thread will appear cloudy

Earlier this year, TECH-G was released in a test phase where users can try it out and give Taulman feedback on its performance. After its release, Taulman sees TECH-G as a new and easier to use material for 3D printing. It offers higher tensile strength and just the right stretch for functional tests. TECH-G is FDA compliant with CFR 177.1315.

PETG Filament: Properties, Learn how to Use, and Finest Manufacturers

3D Insider is ad-supported and earns money with clicks and other opportunities.

Although PLA and ABS are still the most common filaments used in 3D printing today, alternative materials are becoming increasingly popular. One of these alternative options, PETG, has become popular because of its exceptional durability, good adhesion, and resistance to degradation by water and other chemicals. If you’re wondering what exactly PETG is and how to work with it, you’ve come to the right place.

What is PETG?

PETG is a variation of the very popular polyethylene terephthalate (PET). PET is one of the most common plastics in the world today and is used in food containers, water bottles, and even clothing fiber. Due to its high mechanical strength, its resistance to extreme temperatures and its ability to restrict moisture, it and its various variants are useful in the food industry, as a thermal insulation material or as a precursor for engineering resins.

The addition of glycol during the polymerization process results in the formation of a “glycol-modified” PET or PETG. The addition of glycol results in plastic that is more durable, less brittle, clearer, and easier to use. PETG is widely used for outdoor signage because of its excellent printability and lamination properties. Other uses for PETG include medical and food containers, electronic devices, credit or gift cards, store fittings, and prostheses.

Why use PETG?

As mentioned earlier, PETG offers durability and impact resistance that is even superior to PET. Working with PETG is also easier than PET, as PET easily becomes cloudy and brittle when overheated. The added glycol in PETG removes this limitation by preventing the material from crystallizing and thus becoming fragile. Its temperature-resistant properties also make PETG an excellent material for containers for medical applications, as PETG can be sterilized or autoclaved without it breaking.

PETG has shown good chemical resistance, be it to acidic or alkaline substances. It also retains the excellent moisture blocking property of PET, making it a good choice for containers for water or other beverages. It is also suitable for containers, which are easier to grip due to their softer and pliable nature.

In terms of how easy it is to 3D print, PETG’s temperature resistance and excellent layer adhesion have made it less prone to warping and shrinkage. It has been described that PETG filaments have a combination of the best properties of PLA and ABS: They are stronger and more temperature-resistant, yet easy to process.

As a thermoplastic, one of the most interesting properties of PETG is that it is 100% recyclable. It can be shaped and reshaped over and over again by heating without the material deteriorating. This means that waste material (e.g. backing) and printing errors can be converted into new prints and this process can be repeated indefinitely.

Due to its properties, we recommend the use of PETG filaments for printed products that may be exposed to sudden or prolonged loads, such as: B. Protective components and mechanical parts. PETG filaments are also a good material when printing parts that are supposed to come into contact with food material, e.g. B. Cups and food containers.

How do you work with PETG filaments?

The first thing to do when working with PETG filament is to ensure that the printer model you are using has extruder temperatures of 220 to 245 ° C. The bed temperature must also be kept at 70 to 75 ° C or a little higher in the first shifts.

We achieved the best results with blue painter’s tape for adhesion to the print bed. With or without heating, this type of adhesion results in a fairly smooth floor finish. If you want a glossy, glass-like finish, you’ll need to use a heated borosilicate glass print bed. For a heated glass bed, we recommend a temperature of 50 to 60 ° C. A thin layer of non-perfumed hairspray also improves adhesion. BuildTak print surfaces are also very suitable for the adhesion of PETG prints.

If you want your print to be exceptionally durable, we recommend fanless printing. If the molten PETG comes into contact with the previous layer at a high temperature, this leads to very strong layer adhesion. The disadvantage of this strategy is that it may tend to be stringed, resulting in a print that is less detailed or may need further processing. To fix this, we recommend printing without a fan for the first two layers and with a fan (100%) for all subsequent layers.

The high printing temperature of PETG makes working with it susceptible to clothing, especially if the extruder nozzle is placed too close to the bed. We recommend leaving a gap of approx. 0.2 mm between the nozzle and the print bed so that the melted plastic has more space to deposit. If this setting does not work for you, we recommend moving the nozzle away from the bed in small steps until there is no longer any visible covering.

If strings are still appearing, you may need to slow down the print speed. We recommend a setting of approx. 55 mm / s or even only 15 mm / s.

Another thing to note is that PETG filaments are hygroscopic, which means they are actively absorbing moisture from their surroundings. PETG plastic must be packed in an airtight container, e.g. A vacuum-sealed bag with a couple of desiccant packs. Printing with wet PETG filament results in a product that is significantly weaker than expected.

What are the limitations of PETG?

The main drawbacks to using PETG are finding the “sweet spot” for your printer’s settings to produce a print that is both permanent and detailed. Certain settings are required to get the best results with PETG printing. PETG isn’t as easy to work with as PLA, which means you’ll likely need to experiment for a while before you get good results. Once you get the settings that work, printing with PETG should be a breeze.

PETG is a very poor choice of material for support structures, precisely because of its excellent adhesion. Removing support structures made with PETG can be very difficult, but not impossible.

The resulting PETG print, while permanent, can be weakened by UV light. If you are printing a product that is designed to be exposed to constant outdoor exposure, you can expect its strength to decrease over time. PETG products are also more easily scratched than those made from PET.

What are the best brands of PETG filament?

PETG is an easy-to-make material and has developed a large market for 3D printing. Manufacturers have responded with a variety of PETG filament products, the best of which are featured here.

MatterHackers’ PETG filament line of products is one of the most popular today. It is available in different colors, e.g. B. White, Green and Blue. Your PETG filaments are sold in 3.00 mm size and 1 kg spools. MatterHackers PETG filament has performed exceptionally well in terms of both strength and appearance, making its product one of the first choices if you are looking for a good PETG product in the market.

More and more 3D printing users have started to see the benefits of working with PETG filaments. Although they can be difficult to work with at the beginning, as they are less forgiving than PLA when it comes to printer settings, this “sweet spot” is well worth the effort for prints that look great and have excellent mechanical strength.

Prints made with PETG are sturdy but have just the right amount of compliance, which makes them extremely durable. The strength of PETG doesn’t stop there: it has excellent layer adhesion, has a lower chance of warping or shrinking, and is 100% recyclable. If you want to go beyond PLA and ABS, we recommend taking PETG for a spin.

Warning; 3D printers should never be left unattended. They can pose a fire hazard.

Evaluation: Amazon Fundamentals 3D printer filament PLA and PETG

Recently, the leading online marketplace Amazon sparked the rumor mill for 3D printing with the launch of its own Basics FFF / FDM filament brand. To examine the new range of materials for themselves, the 3D printing industry ordered two spools of the filament.

This test examines the print quality of Amazon Basics Black PLA and Red PETG using standard parameters set by our engineers in the 3D printing industry. The tests were carried out using two inexpensive desktop 3D printers, a Snapmaker 3-in-1 and a Wanhao Duplicator 9. The printing profiles for each of these machines are recorded at the end of the article.

Amazon Basics Filament Unboxing and Delivery

When ordering Amazon Basics filaments, a delivery time of 1 to 3 months was initially specified. With the order on July 25th, the coils arrived on August 14th. The wait on delivery is expected as the order was taken by Amazon.com and the spools were initially sent to a company depot in California prior to shipping to the headquarters of the 3D printing industry. The filament is currently at an early stage of availability. As soon as the demand is assessed, Amazon could update the long delivery times.

Upon arrival, both coils were neatly packed in cardboard boxes and individually sealed with a bag of desiccant in resealable packages to protect them from dust / contamination.

The windows in the coils are a helpful feature in the design, and details of the materials are given in five different languages ​​(German, French, English, Spanish and Italian) for America and Europe. This suggests that Amazon plans to make the filament available in a larger number of regional outlets in the future.

Calibration test

For each filament, the engineering team printed three calibration test models in 3D: a 3DBenchy, an XYZ cube, and a Cali Cat. These models were 3D printed to get the optimal quality of the filament with a layer height of 0.2mm on both 3D printers and a printing speed of 0.2mm 40 mm / s on the Snapmaker and 50 mm / s on the Wanhao Duplicator 9. The models were also 3D printed with 15% filling on the Snapmaker, and the Wanhao Duplicator 9 was set to 10% filling.

As a base filament, PLA is best suited for prototypes, toys and figures. With greater rigidity and chemical resistance than ABS, PETG is a polymer for more functional use.

Compared to 3D printing, the quality of the models is consistent. PLA figures are of good quality, although the finish is expected to be better on PETG models.

Layer lines in the red 3D printed PETG calibration models are less visible than those of the black PLA. The surface of the PETG has a shiny gloss.

Detailed 3D prints

As a further test of the print quality of the material, the engineers printed detailed 3D models of Michelangelo’s Pietà sculpture.

Only the Snapmaker 3D printer was used in this experiment. The layer thickness was set to 0.1 mm with 15% filling and 50 mm / s printing speed.

Both filaments have managed to capture small features, such as eyes, mouth, hair, folds of fabric, of the Pietà model and to achieve a good glossy surface. Removing the supports on a model with such fine features is always difficult, but a clean finish is achieved on any support area.

Tested for purpose

To further verify the quality of the black PLA used for making figurines / toys, engineers 3D printed a model of the Maiwand Lion statue in Forbury Garden, Reading, UK.

All settings for this print on the Snapmaker 3D printer stayed the same as for the calibration tests in order to save time during the print as this was selected as a fast prototype / toy. Due to the layer height of 0.2 mm and the size of the model of approx. 650 mm x 250 mm x 350 mm, there are noticeable burrs in the finished lion. Over time, of course, the lion could also be 3D printed with a layer height of 0.1mm for a smoother finish. Despite the ridges, the lion maintains a strong shape.

Amazon Basics Filament – final thoughts

The team’s final verdict is that both Amazon Basics PLA and PETG produce good quality 3D prints and are easy to work with. Other online reviews had found an inconsistent color with the red filament, but no such error was found in this report.

At a single price of $ 19 per 1kg spool, engineers also noted the value for money of the material, especially given the superior processing of PETG. One final seal of approval was that an engineer in the 3D printing industry said he would buy the material for his personal work.

MakerBot releases PETG specialty filament for METHOD 3D printer » 3D Printing Media Community

3D printer manufacturer MakerBot expands its material portfolio for its METHOD 3D printer to include the approval of polyethylene terephthalate glycol or PETG. The PETG filament is the first specialty material that MakerBot brings out for its METHOD printer.

MakerBot introduced its METHOD 3D printer in December 2018 to bridge the gap between the desktop and industrial 3D printer markets. The 3D printer has a number of features that make it suitable for professional use, including a circulating heated chamber, double power extruders, and dry-sealed material chutes – all at an affordable price.

With the release of its special PETG filament, MakerBot now wants to give its METHOD users access to high-performance technical materials. The company also announced its intention to bring more specialty materials to its desktop additive manufacturing system.

“PETG is the first in a new line of materials for METHOD,” said Nadav Goshen, MakerBot CEO. “Our customers have asked for different materials for a variety of applications that require high strength and durability. PETG is one of the most widely used polymers today. Because of its advanced properties and versatility, we consider PETG an excellent material for the production line and short-term production runs. “

With the new PETG filament, engineers and designers can easily 3D print industrial parts, including functional prototypes, fixtures and fixtures, and even end-use parts. The material has a number of properties, including a heat resistance of up to 70 ° C and a strong layer adhesion that minimizes shrinkage and warping during the entire printing process. PETG is also characterized by good moisture and chemical resistance. For best results, the material should be used with an adhesive on the build plate.

METHOD users can easily combine the new PETG material with water-soluble PVA carriers thanks to the double extruders of the 3D printer. In terms of print quality, the PETG filament should be printed smooth and odorless. The final parts have good ductility and a shiny surface.

PETG is becoming increasingly popular as a 3D printing material because it combines many of the attractive properties of PLA and ABS such as durability, strength and flexibility. The material is effectively a modified version of PET, a common household plastic used in water bottles and all sorts of other items, which is less brittle and more impact resistant.

MakerBot’s new PETG filament is the latest filament to be developed for the company’s METHOD 3D printer. The company also has a range of precision materials for its professional 3D printer, which include MakerBot Tough, MakerBot PLA, and MakerBot PVA. These materials cover a range of prototyping, jig, and end-use parts use cases.

The new PETG material can be ordered in three colors: natural, red and black. It is priced at $ 69 per spool.
