PLA (Polylactic Acid)

Used For: Concept models, prototypes, decorative pieces, cosplay props, toys, figurines

This is our most popular material—and for good reason! This versatile material is inexpensive and prints extremely reliably. We use PLA for most decorative items, quick prototypes, and even some functional parts. Our PLA brand of choice is Polymaker, who offers a huge range of colors and finishes to choose from. With the addition of our multimaterial unit, we can now harness this spectrum of filament colors to create full-color prints!

Pros:

Inexpensive

Rigid Form

Wide Range of Colors & Finishes

Cons:

Degrades in Sunlight

Not Suitable for High Heat or High Load

Not Suitable for Chemical/Water Submersion

TPU (Thermoplastic Polyurethane)

Used For: Flexible parts, gaskets, medical device prototypes, impact absorption/dampening parts

If your part needs some flex, TPU is the material you need. The finished prints have similar qualities to a dense silicone, and we can control the stiffness by using more or less infill. Some great applications for TPU are custom shaped gaskets, protective cases, grips covers, and end caps.

Pros:

Highly Flexible & Soft

Impact Resistant & Vibration Dampening

Very Durable in a Wide Range of Conditions

Cons:

Lower Detail Accuracy

Not Suitable for Some Industrial Applications

Higher Cost Due to Print Difficulty

PETG (Polyethylene Terephthalate Glycol)

Used For: Mechanical parts, snap-fit enclosures, functional prototypes, outdoor pieces

Our second most used filament in the shop is PETG. This is perfect for most mechanical applications such as hinges, printed bolts/screws, clips, gears, and more. It has a glossy finish and is chemical resistant. It can withstand higher temperatures and has great light diffusion, making it perfect for 3D printed lamps and light covers.

Pros:

Waterproof

Flexible Parts

Impact Resistance

Cons:

Can Have a Rough Cosmetic Appearance

Derived from Petroleum

More Challenging to Print

Nylon (Polyamide) Composites (Carbon Fiber, Fiberglass)

Used For: Jigs, complex assemblies, high performance parts, enclosures, connectors

Our printers have been tested and optimized to print with more advanced filaments like nylon composites. We utilize these filaments for more high performance parts, leveraging the benefits of special additives like carbon fiber, fiberglass, etc. These added materials improve the durability and strength of finished parts, allowing us to print end-use parts for more industrial applications.

  • Carbon fiber blended nylon filament is great for parts that go through high impact, heat, or just a lot of general wear and tear.
  • Glass fiber blended nylon (fiberglass) can be used for high temp parts, as well as parts that are used in electrical applications.

Pros:

High Tensile Strength

Durable Yet Lightweight

Long-Lasting Parts

Cons:

Very Complex to Print

Higher Print Cost

Steeper Turnaround Times

High Quality Materials Make High Quality Prints

We use a wide range of high quality filaments to accommodate a wide range of projects. From basic, inexpensive PLA made from plant-based materials, up to specialty industrial, nylon blend materials meant to work hard, we have access to anything your project may need!

We work specially with Polymaker filaments to ensure a consistent quality to all of our prints. Learn more about some of our most common filament types by selecting one from the list:
