PLA
PLA or Polylactic Acid is an eco-friendly biodegradable hard plastic made from renewable resources such as corn starch and sugar. PLA is a wonderful material for 3D printing as it melts at a relatively low temperature and demonstrates much less part warping than other materials such as ABS. If actively cooled, much sharper details can be seen on printed corners without the risk of cracking. The increased flow can also lead to stronger binding between layers, improving the strength of the printed part. With its characteristics of high strength and rigidity, glossy or matte surface, fine details, low toxicity and good chemical resistance, PLA is our number one recommended low-cost choice for general 3D printing applications and is available in a wide variety of colors.
New! POLYSMOOTH plastic is similar to PLA but it can be "smoothed" with alcohol using a special vapor-smoothing machine. The smoothing process virtually eliminates the layer lines that are typically seen in 3D prints, leaving a glossy smooth finish. We are currently offering PolySmooth prints in various colors, just choose "POLYSMOOTH" when you order your prints or contact us for details.
PET or polyethylene terephthalate and its modified vairants PETG and PETT are Thermoplastic Copolymers best known as the material making up the familar clear water bottles found in the grocery store. PETG, the most common form used for 3D printing, has the reputation of combining the functionality of ABS (stronger, temperature resistant, more durable) and reliability of PLA (easy to print) in one material. PETG is strong and durable with great chemical resistance and layer adhesion and low odor while printing. This material has become a popular alternative for makers looking to do away with the odor and printing difficulties of ABS, as well as those eager to take the next step up from PLA. It's also considered food-safe. The only drawback with PETG is that because it has such good layer adhesion, it does not make a good support material so prints using PETG should be designed with minimal support requirements.
ABS plastic, or Acrylonitrile butadiene styrene, is a hard plastic commonly used to produce products such as Lego bricks. ABS is a bit less rigid and slightly more flexible and less brittle than PLA, and melts at a higher temperature. It is resistant to water and alcohol-based solvents, but will dissolve in acetone. In contrast to PLA, ABS can be sanded and machined. The drawbacks of ABS when 3D printed is its tendency to warp, even with a heated bed, and that heating ABS to extrusion temperatures can produce a hot plastic smell and toxic fumes of acrylonitrile. Because of these challenges, we are primarily offering ABS as a 3D printing material on smaller prints.
ASA plastic, or Acrylonitrile Styrene Acrylatee, is a more weather-resistant alternative to ABS, offering superior UV resistance and durability for outdoor use. As a copolymer of acrylonitrile, styrene, and acrylate, it offers a superior weather-resistant alternative to ABS plastic, providing improved durability, impact strength, and chemical resistance for use in automotive components, appliances, and building materials.
Nylon is the preferred material for printing parts that require maximum strength, durability, chemical resistance and some pliability. It is softer than ABS but harder than rubber. Unlike ABS, nylon is a 100% thermoplastic, so it can be re-melted and used again and again without losing its bonding properties. Nylon readily absorbs moisture from the air, so special precautions must be taken to dry the filament and keep it in a low-moisture environment during extrusion. Although nylon can be a more difficult material to 3D print than PLA and ABS, new formulations such as Taulman Bridge nylon are opening up greater possibilities for printing nylon at a lower temperature and with better bed adhesion. With Taulman bridge, there is almost no de-lamination and the bonding of thread-to-thread layers is very impressive. We offer Taulman bridge nylon as an option for applications such as laboratory parts, gears, springs, tubes, and particularly for use in the 3D printing of prosthetics. Nylon comes at a higher cost than PLA and only comes in limited colors, such as translucent, white, gray, and black.
Flexible Filament, TPU, or Flex for short, are soft and pliable materials that enable the creation of stretchy, bendy, and rubber-like objects such as flip-flops, stretchy bands, functional hinges, joints, and rubbery parts. Available in a variety of colors, Flex filaments such as NinjaFlex, FilaFlex, and FlexPLA are some of the newest materials capable of extending the capabilities of many of today’s 3D printers.
Metal Composite filaments are usually PLA blended with various metal fibers to produce a metallic looking print. These include carbon fiber-infused filaments, stainless steel, magnetic iron, bronze, brass, and copper. The resulting prints take on the color of the base metal and can be polished to give a pleasing looking patina reminisent of antique or weather-worn metal sculpture.
Wood-based filaments are wood-like 3D printing materials that give 3D printed objects the look and feel of wood. It also imbues parts with other wood-like attributes, such as the ability be cut, painted, and sanded. It is possible to give parts printed in wood-infused filaments a simulated alternating light/dark wood-grain appearance by varying the temperature during printing. Available by special request only.
