Filament Dyeing | Hackaday

Manufacturers dye all kinds of 3D printer filament on their factory lines. why can’t we [Richard] goes one step further and creates its own multi-colored nylon rollers. Printing with these rolls creates a living pattern that simply demands our attention and asks us: how on earth?

[Richard’s] Tie-dye adventure is neatly documented in the blog. He simply spools up a roll of nylon and dyes subsections of the spool a different color. When the filament is “palletized” to taste, parts of the printer will burst with a noticeable rib pattern.

It is worth noting that nylon is extremely hygroscopic, and dyeing filaments in a bath full of colored liquid is sure to add moisture. On the other hand, the ability of nylon to absorb water could be why it stains so well. Even so, the filament must be oven dried (or equivalent) to print successfully. After drying, [Richard] doesn’t seem to have any printing issues and the results speak for themselves

3D printers may be frequent fliers on these sites, but we still love to see small changes that improve visual appeal. In addition, this trick produces spectacular results without any changes to the printer. If this job is just too much work for you, we recommend using a felt-tip pen.

Researchers use industrial wood-waste to make FDM/FFF wooden filament

Scientists at Michigan Technology University in Houghton have successfully created 3D printable wood filaments from furniture wood waste.

The success was revealed in a research report co-authored by open source champ Joshua Pearce. The paper investigated the possibility of converting furniture waste into wood filaments to reduce the environmental impact of wood waste.

The wood filament was made using only open source software and hardware.

Manufacture of wood filaments from waste

According to the paper, the furniture industry in Michigan alone produces more than 150 tons of wood waste every day.

In a four-step process, the scientists demonstrated the possibility of producing wood filaments with a combination of wood waste and PLA plastic in 3D printing. The mixture of these two materials is better known as wood-plastic composite (WPC).

In the first step, wood waste was acquired from various furniture manufacturers in Michigan. The waste contained solid boards and sawdust made from MDF, LDF and melamine.

These solid slabs and sawdust were reduced to microscale for the production of WPC filaments. The waste material was hammer milled, ground in a wood chopper, and sieved using a vibratory ventilator using an 80 micron mesh screen.

At the end of this process, the wood waste was in a powder state with a granular component of cereal flour. The material was now referred to as “waste wood powder”.

This entire process was necessary to make the wood mixable with PLA.

The next step was to make PLA to mix with the waste wood powder. PLA pellets were heated to 210 ° C until they became stirrable. The wood powder was added to the molten PLA mixture at varying wood-PLA weight percentages (wt%) between 10 wt% -40 wt% wood waste powder.

As soon as the desired mixing quantity and quality was achieved, the material was left to cool.

The solidified material was put back into the wood chopper to prepare the open source Recyclebot, a plastic extruder for filament production.

The filament produced had a thickness of 1.65 mm and a thinner diameter than the standard 3-D filament available on the market, ie 1.75 mm.

3D printing with open source wood filament

The wood filament was tested by making various items such as a wooden cube, a door knob, and a drawer handle. Due to the mechanical properties of the wood thread, adjustments were made to the Delta RepRap and Re: 3D Gigabot v. 3D printers used in the study. GB2 made. The changes included modifying the extruder and controlling the printing speed.

Printing wood to an ideal temperature is also an important factor as high temperatures can char the wood and clog the nozzle. In this case the wood filament was printed at 185 ° C.

The researchers showed that it is convenient to make wood filaments from waste wood from furniture. However, you raised important points for future studies. This included the economic and environmental impact, details of mechanical properties and the possibility of industrial scale production.

The paper concluded: “This study has shown a technically feasible method for upcycling wood waste from furniture into usable 3D printed parts for the furniture industry. By mixing PLA pellets and recycled wood waste material, filament with a diameter size of 1.65 ± 0.10 mm was made and used for printing a small variety of test parts. This method developed in the laboratory can be adapted to the requirements of the industry, as the process steps are straightforward. Small batches of 40 wt% wood were made but showed reduced repeatability, while batches of 30 wt% wood with ease of use showed the most promise. “

The research paper covered in this article is titled Wood Furniture Waste Based Recycled 3D Printing Filament. It is co-authored by Adam M. Pringle, Mark Rudnicki and Joshua Pearce.

FIASWI protests anti-dumping duty on nylon filament yarn | Surat News

FIASWI protests anti-dumping obligation on nylon filament yarn | Surat Information

SURAT: The Indian Artificial Silk Weaving Association (FIASWI) and Powerloom Weaving Associations on Saturday urged the chairman of the Lok Sabha House Committee, CR Paatil, to request his intervention in the central government’s assessment not to impose an anti-dumping duty on nylon filament yarn.
FIASWI Chairman Bharat Gandhi met Paatil, who is also a Navsari MP, along with the head of the Powerloom sector.
FIASWI sources said that out of 12 yarn spinners in the country, only two leading yarn spinners have applied to the General Directorate for Anti-Dumping Duties (DGAD) for an anti-dumping duty on nylon filament yarn imported from China, South Korea and other Asian countries. If the DGDA agrees, more than two lakh powerloom machines will be shut down, leaving more than 1.5 lakh workers unemployed.
Bharat Gandhi said: “Over 10,000 weavers and their families in Surat will suffer from the imposition of an anti-dumping duty on nylon filament yarn. The industry has suffered from the anti-dumping duty on nylon yarn for 11 years, which was canceled by the government in 2018 and is now being reviewed by the DGAD. ”
Gandhi said the anti-dumping duty on yarn will increase imports of cheap fabrics from China and Bangladesh. In 2018-19, $ 2 billion worth of garments and fabrics were imported from India.
“Domestic weavers cannot compete with cheap fabrics imported from China and Bangladesh. Spinners are unable to produce nylon yarn that meets the standards set by China. However, the weirdos are aiming for an anti-dumping duty so that they can run a price cartel in India, ”said Gandhi.
Ashish Gujarati, Head of the Powerloom Sector, said: “Not only Surat, but also powerloom centers such as Ludhiana, Bhiwandi, Amritsar, Bhilwara and Varanasi will suffer from the anti-dumping duty on nylon yarn. We asked CR Paatil to take up the problem with the central government and help the industry. ”

Superior BioCarbon 3D develops engineering grade wood-based 3D printer filament

A Canadian bioplastics company, Advanced BioCarbon 3D (ABC3D), has developed wood-based bioplastics for 3D printing.

ABC3D was founded in 2016 and was chosen as one of the world’s top five hundred deep tech startups by Hello Tomorrow, a French tech accelerator. ABC3D’s mission is to develop sustainable carbon-free plastics for 3D printing to mitigate the deteriorating environmental situation.

ABC3D environmental scientist Kim Klassen stated, “If extreme weather events continue to occur, it will disrupt every part of society. Therefore, climate change is important above all to other environmental issues, and this is exactly what this company is addressing through product development and sustainable bioplastics made from renewable raw materials. “

“Our products are CO2 negative, which not only reduces the impact on climate change, but also helps to remove greenhouse gases from the atmosphere.”

Technical quality bioplastics

Although bioplastics are available in industry, the ultimate goal of ABC3D is to produce environmentally friendly bioplastics for technical applications. The company prides itself on the fact that its product is superior to other bioplastics made from renewable resources and is non-flammable and moisture-resistant.

Darrel Fry, CEO of ABC3D, said, “People often consider bioplastics to be single-use products with little functionality, but our products are incredibly highly functional, have exceptional heat resistance, and are lightweight at the same time. For example, our goal is to use this material to 3D print something like a piston for your car – it’s so heat-resistant and also very strong. “

Sustainable development

ABC3D’s bioplastic filament is made from scrap wood, so the company does not compete with forest companies. In fact, the wood used by ABC3D comes from poplar (or poplar) trees that are felled by forest companies during wood collection. And since there is no market for poplars, they stay in the forest.

The 3D printing filaments produced by ABC3D are a mixture of 60% plastic and 40% wood, which are mixed according to the method developed by ABC3D, in which resin is extracted from the waste wood. And the leftover wood is turned into a polymer. The resin is then added back to the plastic and this gives the material its heat-resistant and moisture-proof properties.

Classes explained the process, “The process uses green chemistry and starts with wood chips from the forest industry that are mixed with a solvent and subjected to a series of pressurized heating and cooling phases to extract the resin from the wood chips. All solvents from the manufacturing process are returned to the system for reuse. “

The biomaterial was developed with the help of a joint grant of US $ 300,000 granted to ABC3D and Selkirk College by a government-sponsored innovation cluster, Innovate BC.

ABC3D’s materials are currently being tested in the MIDAS (Metallurgical Industrial Development Acceleration and Studies) factory laboratory in Trail.

ABC3D is currently scaling production to begin sales in Q1 2019. Fry said, “We aim to start sales of 3D filaments in Q1 2019 and then a range of different filaments with additional features such as carbon fiber reinforced filaments, conductive filaments, and filaments reinforced with other wood fibers through our first products which are mixed traditional printing filaments. “

“Our company proves that we can produce sustainable, economical and high-performance plastics from wood.”

The nominations for the 3D Printing Industry Awards 2019 are open. Please tell us the best 3D printing applications.

Additive Composite and Add North 3D develop 3D printing filament with neutron shielding capabilities

Swedish 3D printing material developer Additive composite Uppsala and Add North 3D worked together to develop a polymer composite for radiation protection applications.

The material called Addbor N25 is a combination of boron carbide and nylon and was developed and manufactured as a filament optimized for 3D printing. The radiation protection capabilities are provided by the boron carbide element which provides effective absorption against neutrons. Additive Composite explains that the material can therefore be useful in research facilities, in the nuclear industry or in other places where radiation sources are used. Addbor N25 can be purchased from the Additive Composite website starting at SEK 9,500 ($ 988) / 750g.

Adam Engberg, CEO of Additive Composite stated, “Additive manufacturing is changing the number of products that are designed and manufactured. We believe that Addbor N25 is contributing to this development and helping both industry and large research institutions to replace toxic materials that could ultimately contaminate the environment. “

“Our new product is the first in a series of radiation protection materials that we are currently developing.”

Filament production in Sweden

Additive Composite was founded in 2018 and aims to develop new solutions for research and commercial applications that take advantage of additive manufacturing. The company, based in Uppsala, a city near the Swedish capital Stockholm, mainly focuses on the development and marketing of composite materials for additive manufacturing.

With its developed materials, the company also offers an additive manufacturing service for users to manufacture individual custom components as well as small to medium-sized batches. The composite selection for Additive Composites includes gadolinium oxide (Gd2O3) composites, tungsten composites and more.

Add North 3D, on the other hand, is a filament manufacturer that mainly deals with the production of sustainable plastics such as PLA, which are made from renewable resources such as corn starch. Part of the company’s bioplastics research is funded by the Swedish government innovation agencies Vinnova and Almi.

Add North 3D not only develops novel materials with Additive Composite, but also maintains an established partnership with other Swedish developers of graphene nanocomposite materials Graphmatech. The two companies formed a partnership in 2018 to develop a new range of Graphene-based materials for use with FFF / FDM technology. This led to the development of Koltron G1, their first jointly developed product, made with Graphmatech’s Aros graph Material. The filament is a highly electrically and thermally conductive polymer for additive manufacturing. It is also flame retardant and resistant to a range of chemicals, UV light and high continuous working temperatures.

The Addbor N25 filament

The development of the Addbor N25 filament is based on original research at Uppsala University. The material, combined with the freedom of design offered by 3D printing, was designed to provide effective shielding against scattered radiation, as manufacturers can create complex shapes for any situation.

Additive Composite explains that the new filament is a suitable alternative to cadmium metal, a toxic metal commonly used in industrial workplaces. The company suggests that with the added benefit of geometric flexibility, the Addbor N25 filament could potentially replace the use of cadmium for radiation protection applications. Boron carbide makes up 25 percent of the total weight of the filament. The nozzle temperature of the Addbor N25 is between 250 and 270 degrees, has a tensile strength of 50 to 58 MPa and a flexural strength of 52 to 81 MPa.

Renegade 3D pen uses plastic bottles and bags as filament

Renegade 3D pen makes use of plastic bottles and luggage as filament

There are several 3D printing pens that use plastic filaments to create 3D structures that you can actually hold in your hands. One of them is the 3Doodler, who we spent time with in January 2015. What they all had in common was that the filaments used tended to be expensive. That has changed with a new 3D pen that is called on Kickstarter and is now called Renegade. This pen can print with these regular filaments, but the really cool part is how you can use plastic from bottles or old bags to create your artistic creations.

The Renegade pen has a screw advance mechanism and heating system. In this way, the pen can transport, destroy and melt the plastic tape made by the ChupaCut plastic bottle shredder. This rotating screw head pushes the plastic forward evenly and extrudes the molten plastic out of the nozzle. The plastic cools down quickly and results in a stable 3D structure.

The manufacturer says the device has “virtually no material limitations”. The pen is designed to use 5-7mm strips cut from PET plastic bottles, plastic bags or plastic files 0.14-0.35mm thick. Standard filaments made of PLA, ABS, nylon, TPE, HIPS, wood and other filaments with a diameter of 1.75 mm can also be used.

The Renegade pen is available in matte black or matte white and has a detachable attachment and a spool for tape. With the ChupaCut 3, 6, 9 or 12 mm plastic bands can be created. The Renegade pen is on Kickstarter and looking for a little over $ 32,000. He has raised over $ 38,000 at the time of writing. The Renegade pen and spool cost about $ 78. If you want the pen along with a ChupaCut bottle shredder, it will cost you around $ 118. A pen, cutter, and fancy stand kit costs $ 131. The dispatch is expected in January.

WiZ Connected ST19 Filament Dimmable bulb review: This vintage Wi-Fi bulb is well suited for accent lighting

WiZ Related ST19 Filament Dimmable bulb assessment: This classic Wi-Fi bulb is nicely suited to accent lighting

Anyone looking for a stylish, yet affordable, vintage smart lamp that doesn’t require an expensive hub should consider WiZ Connected’s dimmable ST19 white incandescent lamp. This Wi-Fi enabled light bulb is screwed into a standard E26 socket. It’s too dark to illuminate an entire room (this is a 40-watt equivalent), but it works great as accent lighting in a dining or living room.

Setting it up is a breeze, and you can put the dimmable light on a schedule, set it to different lighting modes, group it with other WiZ Connected lights, and control it with voice commands from Alexa and Google Assistant.

Design specifications

WiZ Connected (owned by Signify, the company behind popular lighting brand Philips Hue) offers two versions of its dimmable ST19 incandescent lamp: one with amber glass (the one we tested) and one with clear glass. In addition to the elongated ST19 lamps, WiZ also sells standard A19 lamps and spherical G25 bulbs.

This review is part of TechHive’s coverage of the best smart lighting products. where to find Reviews of competing products, as well as a guide for shoppers on the features to consider when shopping.

The ST19 lamp has a lifespan of up to 15,000 hours and is equipped with an E26 base that can be screwed into a standard light bulb socket. The amber version of the light bulb is designed for a very warm white 2,000 Kelvin, while the clear light bulb is designed for a slightly cooler (but still warm) 2,700 Kelvin. Four linear LED filaments are located in the light bulb.

Both the clear and amber versions of the WiZ incandescent lamp ST19 emit 350 lumens at full brightness, which is too weak to illuminate an entire room or work area. Instead, think of decorative or accent lighting.

wiz connected st19 light bulb lifestyle Ben Patterson / IDG

The ST19 incandescent lamp from WiZ Connected is too dark to illuminate an entire room, but it does provide a nice accent light (especially with this ugly ceiling light in my office).

configuration

Commissioning the ST19 incandescent lamp from WiZ only takes a few minutes. Once you’ve downloaded the WiZ app (assuming you haven’t already), you can add the Wi-Fi enabled lamp to your WiZ home in two ways: either through smart pairing or manually. The Smart Pairing setting allows you to quickly connect a number of WiZ lamps at the same time. However, this will only work if your phone is connected to your router using the 2.4 GHz radio band. Therefore, you may need to disable your router’s 5GHz wireless network first (you can turn it back on once the pairing process is complete). With manual pairing, however, a connection to each new lamp is established via a temporary Wi-Fi signal. This is a tedious process, but when you do so you don’t have to mess with your router’s dual band settings.

In any case, I managed to add the ST19 lightbulb to the app in a matter of minutes (both the “smart” and manual pairing method worked just fine) and I added it to one of the rooms in my house as defined in the app definition (in this case “Office”), in which I also installed a few other WiZ lamps.

Features, app support and smart home integrations

Once you’ve used the WiZ Mobile App to group the ST19 bulb with your other WiZ Smart Lights, you can control it, set a schedule, and even set a daily “rhythm” with the WiZ Mobile App.

Since the lightbulb is only dimmable and non-tunable (meaning you can’t change the color temperature), there are only a few lighting modes available, including the standard “white” mode, a night light mode, and the “progressive” wake-up and bedtime modes that the light bulb Gradually brighten and dim over a period of 30 minutes.

wiz connected st19 bulb modes Ben Patterson / IDG

With the WiZ app, you can activate various lighting modes for the ST19 light bulb, including the dynamic “steampunk” mode. You can also adjust the brightness of the lightbulb, as well as the speed of dynamic lighting effects.

More interesting are a quartet of “dynamic” modes, including a pulse mode in which the brightness of the light bulb is gradually increased and decreased, a candlelight mode in which the filaments flicker gently, and a moody “steampunk” mode which randomly dims the light bulb and brightens, almost as if the lightbulb was connected to a transient electrical current. For each of the four modes, you can adjust both the brightness and the speed of the effect.

In addition to the app for controlling the lamp modes, you can also use the optional Wi-Fi WiZmote, with which you can access four “favorite modes” at the touch of a button. Another fascinating control method is the WiZclick feature, which essentially gives smarts to an otherwise “dumb” light switch by letting you switch between the first two of four preferred modes. Switching on the switch normally activates the first favorite mode, while the second favorite is activated by briefly flipping the switch twice.

The app also lets you set the lightbulb (or a room or the entire house) daily or weekly, activate a random vacation mode to fool potential intruders when you are not at home, or build the lightbulb into a lightbulb light scene. Finally, in a circadian rhythm mode, you can set the wake-up and bedtime times and then automatically change the brightness of the light bulb depending on the time of day.

WiZ’s ST19 lightbulb also lends itself to a wide variety of integrations including Alexa, Google Assistant, IFTTT, Samsung SmartThings, Conrad Connect, Enki, ImperiHome, and Alice. For example, Alexa allows you to turn the light bulb on and off with voice commands, change the mode or room scene of the light bulb, or set up a routine triggered by language, time of day, motion sensor or a host of other conditions. While the ST19 light bulb does not support Apple HomeKit, you can assign WiZ room scenes to a Siri shortcut.

Bottom line

The ST19 incandescent lamp from WiZ Connected checks many of our boxes when it comes to intelligent lighting: It is easy to set up, works without a hub, is equipped with different lighting modes and can be controlled via voice commands. We also love the attractive vintage design, which is perfect for adding a touch of class to a living space. Best of all, it’s inexpensive.
