Nefilatek Wants to Turn Montreal's Waste into 3D Printing Filament - 3DPrint.com

Nefilatek Needs to Flip Montreal’s Waste into 3D Printing Filament – 3DPrint.com

“This industry will bring a lot of improvements to people, but 3D printed objects are made from various plastics and these materials have a terrible impact on the environment. In fact, only a small fraction of plastic waste is well recycled and reused as it should be in ten to fifteen cycles. The rest is burned or sent to landfill. Additionally, a large amount of plastic never ends up in the trash and ends up in nature, which is a critical pollution problem.

“NefilaTek is a new company making environmentally friendly 3D printing filaments from recycled plastic. The idea is to reduce the environmental impact of the 3D printing industry by making high quality filaments from plastic waste from Montreal. The processing of used plastic into useful items is the greatest challenge of our time to reduce the pollution and overproduction of plastic. “

Much of the world’s industrial polymer materials are already being recycled. There are commercial recycling companies trading in regrind ABS, PC and many other materials around the world. These polymers are offered for sale worldwide. In recent years regrind has been more expensive than new pellets made from new resin due to the high demand in some regions. We often hear that the plastics industry is responsible for all plastic diseases, but the global recycling market and use of regrind materials is really impressive. Many polymers can be recycled six or seven times, and if everything is okay, it’s millions of tons. This results in materials with an extended life of many decades through many different uses. As long as there is traceability (to know what additives are in the base material), even high value applications can be investigated. With packaging and single-use items, which usually only last a few days, I think the plastics industry is clearly part of the problem. We need innovative natural, bio-based, compostable or recycled materials to solve the problem of volatile use of polymers for silly applications like a clear pod for a cucumber. In other applications, we can see that market-driven solutions provide an industry that has an incentive to reuse these materials and extend their lifespan.

No bobbin filament is also a huge benefit.

By working with this established regrind industry, Nefilatek would like to offer our market many filament qualities. The really cool thing is that absolutely every single filament manufacturer can do the same.

The company told us, “All of our filaments are 100% 100% filament recycled Raw materials, we don’t have any new plastic in our filament. “

With many polymers this would be difficult, so we are skeptical.

Research and development engineer Angel Chauffray said something that makes us happy: “You have achieved an industrial tolerance for the filament diameter of 1.75mm +/- 0.05. It works at least as well as other filaments with this tolerance. “

Another thing that worried us was that they were also working on new R&D materials like “Dark Blue Polypropylene (recycled from hospitals). “If they manage to create a very exciting material, it would be” carbon fiber reinforced nylon, “which they are working on with a company that recycles carbon fiber. The company has also developed PCs, but has not yet launched them.

The company currently offers ABS and HIPS. HIPS has very interesting properties, but you have to be careful when extruding it. ABS and HIPS should both be used in a sealed printer with carbon and HEPA filters in my opinion. The company is investing in recycling facilities to test and develop more materials in-house. I really like Nefilatek’s approach and would like more people to work constructively with the regrind industry to make high performance filaments from recycled materials.

Bubbly Filament Works Better Than You Think

Bubbly Filament Works Higher Than You Assume

Usually, bubbles in your extruded filament are considered a bad sign, but it turns out that now you can buy filaments that are specially formulated for foam. [Stefan] from CNC Kitchen did some experiments with these bubbly filaments and the results were very interesting.

The filaments in question are VARIOSHORE TPU and LW-PLA, both from ColorFabb. Both filaments have a propellant added to the formulation that releases gas when the temperature rises. This causes bubbles to form, creating a cellular structure that reduces density and increases the flexibility of the printed part. This isn’t the first time foaming has been sold as a feature, but previously it was done in Polymaker’s Polywood filament for aesthetic purposes only.

Before subjecting the materials to his excellent testing procedures, [Stefan] First, the print settings are adjusted. This can be difficult due to foaming, which increases the effective volume of the plastic and requires careful adjustment of the extrusion rate. The foaming in the PLA filament reached its maximum foaming at 250 ° C, at which its density was 44% of the non-foamed filament.

When testing physical properties [Stefan] found that the tensile strength and stiffness of printed parts decrease with increasing foaming, but the impact resistance is improved. He concludes that the lightweight PLA may have some interesting applications due to its lower weight and increased impact resistance, with 3D printed RC airplanes being a great example of this. It should also be possible to change the intermediate layers to effectively sandwich the foamed layers between solid skins.

[Stefan]The videos are an excellent source for those looking to master the intricacies of 3D printing with a variety of materials. He has reinforced prints with carbon fiber, played with extrusion widths, and developed a sophisticated gradient fill technique.

Advancements in Water-Soluble Materials for 3D Printing Support Filament - 3DPrint.com

Developments in Water-Soluble Supplies for 3D Printing Assist Filament – 3DPrint.com

A new material has been developed that is ideally suited as a water-soluble all-purpose carrier for additive manufacturing (3D printing). Its thermal stability and robust adhesive properties make it an ideal carrier system for a wide variety of building materials.

Most manufacturers know how 3D printing enables them to make stronger and lighter parts and systems. Although many different materials can be used to create 3D printed models, the most common thermoplastics used are acrylonitrile butadiene styrene (ABS), polylactic acid (PLA), and polycarbonate (PC).

Complex thermoplastic parts and structures have bridges or overhangs that need to be supported while printing. Since these supports are not part of the model, they must be removed after printing. This post-processing step is important as it affects the final surface finish, strength, and color of the printed part. However, it can be tedious, require the use of harmful chemicals, damage the surface of the model, and decrease productivity. For this reason, it is important to choose the right material for 3D printing support structures.

BREAKAWAY VS. SOLUBLE SUPPORT STRUCTURES

There are two basic categories of materials available for support structures: breakable and soluble. Tear-off support structures are often made from a material that is similar to the printed object. After printing, the carrier is removed by trimming, mechanical breaking or abrasion.

All of these steps add to the labor, and therefore the time and cost of each piece. In addition, removing the 3D printing support structures can leave imperfections on the model surface or break part of the model along with the structure. Also, tear-off props are generally more difficult to remove when working with high temperature materials.

Alternatively, soluble substrates can be removed by adding them to water or a solvent after printing. The use of solvents is undesirable because they are generally volatile organic compounds that are unfriendly to printers and the environment. However, it can also be difficult to work with water-soluble carrier materials. For example, polyvinyl alcohol (PVA) absorbs water vapor from the air, does not adhere very well to printing surfaces, and is temperature sensitive, which can lead to jams. Water-soluble support materials were also extremely difficult to develop.

DEVELOPMENT CHALLENGES FOR SOLUBLE SUPPORTS

The development of water soluble carriers is challenging for many reasons. First, there are a limited number of commercially available resins that are truly water soluble. Many water-soluble polymers are very brittle, which prevents them from converting into filaments. In addition, plasticizing with conventional additives often inhibits thermal stability and adhesion, which severely limits their use in 3D printing.

The first generation of soluble carriers had a number of problems. Some used harmful chemicals or strongly acidic or strongly basic solutions. While some of these are still widely used, resin technology has advanced and there are now a variety of soluble substrates in the commercial market including:

• Highly proprietary resins (Stratasys SR30, SR35, SR100, etc.)

• Resins based on commercially available PVA or polyvinylpyrrolidone (PVP)

• Cellulosic agents such as hydropropylmethyl cellulose (HPMC)

• Exotic polybutenediol vinyl alcohol (BVOH)

However, none of these products are ideal for filaments because they are not thermally stable. Now there is a better material option.

WATER-SOLUBLE RESINS THAT ARE HEAVY ON THE FILAMENT

Infinite Material Solutions recently developed a composite material that is both water soluble and thermally stable. This “out of the box” resin is formulated from a naturally occurring carbohydrate blended with a polymer that is flexible, tough, and water soluble. The new material (branded) AquaSys120) is unique in that it is sturdy enough to be used as a support filament.

This formulation is surprising, since many pure carbohydrates and water-soluble polymers are far too brittle to form a usable filament. Over the years, formulators have made many attempts to plasticize water soluble resins so that they can be converted into filaments. However, the addition of plasticizers often dramatically reduces the thermal stability of the base resin. Plasticizers can also inhibit the adhesion between materials and severely limit their use for 3D printing. AquaSys 120 uses a highly complex process to produce filaments 1.75mm and 2.85mm in diameter that can be successfully used for a wide variety of 3D printing platforms and materials.

MATERIAL ADVANTAGES AND COMPATIBILITY

The individual components of this new material are widely used in industry for a wide variety of applications ranging from packaging and drug delivery to cosmetics and personal care products. The material is hydrophilic, biocompatible, biodegradable, non-toxic and non-carcinogenic based on information available for each individual component.

This new filament material can be used for the most popular 3D printing technologies, including the manufacture of melt filaments and direct material extrusion. It is also compatible with a wide variety of materials including polypropylene, as well as hydrophilic and hydrophobic polymers. It shows excellent thermal stability and other advantages over traditional PVA that make it a more versatile, robust and environmentally friendly material for carrier filaments.

These benefits include:

• Dissolves in water much faster than pure PVA

• Can be printed with a wider range of materials

• Has improved adhesion properties

• Will biodegrade faster than PVA

THERMAL STABILITY AT MUCH HIGHER TEMPERATURES

A leading brand of PVA filament printing at 215-225ºC and a maximum build plate temperature of 60ºC. Alternatively, the AquaSys 120 filament prints at 240-245ºC and a maximum building board temperature of 130ºC.

ADHESION PROPERTIES

The ability to create materials that can adhere to soluble substrates, or vice versa, is critical to successful 3D printing. Poor adhesion between adjacent carrier and building material layers leads to flaking and printing defects.

The new material was developed with improved adhesion properties to address this problem. It is compatible with a wide variety of hydrophobic and hydrophilic materials used in filament-driven 3D printing platforms and continues to be used with new building materials.

Til today AquaSys 120 has been successfully printed with polyamides (nylon), co-polyester (CPE), acrylonitrile butadiene styrene (ABS), thermoplastic polyurethane (TPU), polycarbonate (PC) and polyolefins such as polypropylene (PP). This offers a significant advantage over conventional PVA filaments, which have limited adhesion to CPE, ABS, TPU, PC and PP.

RESOLUTION

In head-to-head dissolution tests with identically printed parts, the new filament material dissolved twice as fast as a leading brand of PVA at room temperature (22 ° C) and more than six times faster at elevated temperatures (80 ° C). 1 shows its kinetics of dissolution against PVA. In contrast to PVA, which can form gels before dissolving and especially at elevated temperatures, the new material dissolves cleanly and without gelation at temperatures> 35 ° C.

DISPOSAL AND BIODEGRADABILITY

The new composite material is based on a naturally occurring carbohydrate that is mineralized very quickly in the environment. The mineralization of this carbohydrate component can take several hours or days. The remaining constituents of the material biodegrade more slowly, but like PVA, they are considered ultimately biodegradable based on respiratory mineralization tests using acclimated sludge from sewage treatment plants.

A new water-soluble carrier material is now available that solves a number of challenging problems in additive manufacturing. This carbohydrate compound takes advantage of the unusual thermal stability and excellent water solubility of a naturally occurring saccharide mixed with a flexible and tough water-soluble polymer. This unique material offers advanced adhesion to a wide variety of building materials, a wide processing window and improved dissolution performance in water without the use of solvents or harsh chemicals.

Don’t Let Your PLA Filament Hang Loose With This 3D-Printed Surfboard

Don’t Let Your PLA Filament Dangle Free With This 3D-Printed Surfboard

People always tend to push the boundaries of what is possible with a 3D printer. This also applies to [AndrewW1977] when he decided to 3D print a functional full size surfboard.

With just over nine full days of printing, 95 unique pieces and 3.1 kg of PLA (excluding all test prints), this is certainly a monumental project. One of the bigger problems [AndrewW1977] the solution was to avoid air pockets in the board. Ideally, you would just want to have one continuous hollow chamber to easily vent all of the air in the board when heated. [AndrewW1977] decided to overcome this problem by using a zero fill for every single piece. The parts were then connected using alignment pins that have a central hole, thereby connecting all of the hollow chambers.

By using a triangular shape, he managed to print all of the parts without assistance. Once glued together, the entire board was covered with fiberglass and epoxy, similar to traditional surfboard building. Unfortunately due to the current situation with Covid19 [AndrewW1977] stops short of showing us the board in action. If you have a 3D printer at home and have a lot of free time during the lockdown, [AndrewW1977] published all files for his surfboard on Thingiverse.

As [AndrewW1977] indicates that in the video embedded below, other people have already done similar projects. From jet boats to electric hydrofoils, water sports and 3D printing seem to be a perfect match.

Military-spec filament produces stronger 3D-printed objects

Army-spec filament produces stronger 3D-printed objects

While consumer 3D printers are great for making models or curios, they’re not always up to the task of creating objects that will withstand real-world use. However, this could change thanks to a new pressure thread.

Compact, inexpensive 3D printers typically use a process known as Fused Filament Fabrication (FFF). A plastic thread is heated to its melting point and then extruded through a nozzle. Successive layers of the molten plastic are deposited on top of one another and form a single solid object when they cool and fuse together.

However, according to US Army engineers, items printed in this way tend to be too structurally weak to be used tough and tough by soldiers in the field. This is a shame because if troops could carry small, cheap 3D printers, they could make parts and tools on-site if needed. And while there are printers that use non-FFF techniques to make stronger objects, these machines are large and expensive, making them impractical for field use.

Under the direction of Dr. Eric D. Wetzel, researchers from the Army’s Emerging Composites Team set out to address this problem. Ultimately, they developed a new dual-polymer filament that would allow consumer 3D printers to make much stronger items using their existing FFF hardware.

The material begins in the form of a cylinder with a star-shaped polycarbonate core which is surrounded on all sides by ABS (acrylonitrile butadiene styrene). Using a proprietary device called a thermal draw tower, this cylinder is heated and drawn out into a thin filament.

Once the filament has cooled, it can be wound onto a roll and then used in a standard FFF 3D printer. Items printed from the material are then heated in an oven and then cooled to ensure that the two polymers fuse together thoroughly.

In laboratory tests, such objects were found to be much stronger than those made from conventional filaments – in fact, they exhibited mechanical properties similar to identical objects made using commercial injection molding techniques. The material’s glow time (heat up and cool down) is currently 24 to 48 hours, but the team hopes to reduce that number to four hours or less.

The army is now looking for industrial partners who might be interested in commercializing the technology in order to use it beyond military applications.

An article on the filament was recently published in the journal Advanced Engineering Materials.
