Currently available plastic types:

PLA (biodegradeable)

PLA is one of the most commonly used filaments in 3D printing because it is so easy to use. PLA has minimal warping and shrinking compared to other materials, which means it thrives when making objects featuring flat surfaces and hard angles, or requiring tight tolerances for fit.

PLA is commonly used for prototypes, educational and architectural models, and artifact replicas. It can also be treated with a variety of post-processing techniques, it is a popular choice for users looking to paint objects after they have been printed, such as costume props and figurines. PLA is relatively brittle, so it is not recommended for thin, high strength applications.


ABS is one of the most popular 3D printing materials in the world because it is strong and easy to print. It’s a durable plastic that can be used for prototypes or functional / end use 3D printed parts.

ABS prints can be sanded or smoothed using an advanced technique with acetone. Experienced users have found that the visible layers on a print can be significantly reduced with an acetone vapor bath (a process in which the ABS print is exposed to warm acetone vapor for a brief period of time). With this technique, you can have ABS parts that are glossy and smooth. This process may also strengthen the parts themselves by binding the printed layers together.


n-vent is a premium polyester 3D printing filament that allows for a combination of strength and detail when 3D printed.When 3D printed, n-vent has a glossy surface finish, is strong and dimensionally accurate due to it’s low shrinkage and excellent layer adhesion.


nGen is engineered for prototyping and production. This co-polyester filament by colorFabb brings together the strength and precision found in Eastman Amphora™ 3300 3D polymer, optimized for desktop 3D printing. nGen handles complex models well, including bridging gaps, holes, and overhangs. It also exhibits minimal warping and responds well to post-processing techniques like sanding.

Interlocking parts, models, figurines, and fuctional prototypes print well due to the low shrink rate and excellent layer adhesion. When 3D printed your objects will be glossy, opaque, and bright. nGen 3D printing filament is an excellent choice for 3D printing in close quarters due to its low-odor and styrene-free nature.
