There are several materials available for the FDM materials. Note that unless explicitly required, ABSplus and ASA will be used interchangeable by the Additive Manufacturing Lab. Below is a short description of each material, as well as a table summarizing the mechanical properties of each material.
ABSplus (ABS) and ASA are the standard materials, and the cheapest/fastest to print. They are suitable for most 3D printing requirements. ASA is slightly more UV resistant than ABSplus, and ABSplus is slightly stronger than ASA.
ABS M30i (M30i) is a biocompatible, sterilizable FDM material.
Nylon 12 (N12) has a very high strength and high fatigue resistance. It works well for parts requiring snap-fit enclosures, high vibration resistance, press fit inserts, and threaded inserts.
Polycarbonate (PC) has a very high strength and toughness, making it an ideal material for functional prototyping of tooling.
Ultem 1010 CG (U1010) is the strongest and highest temperature material we have available. It is also the highest cost. We stock the CG grade Ultem which is biocompatible and sterilizable.
Ultem 9085 (U9085) is flame retardent, with high strength and heat resistance. It offers an excellent cost to performance ratio.
| ABS | ASA | M30i | N12 | PC | U1010 | U9085 | |
| Tensile Strength, Yield XZ | 31 MPa | 29 MPa | 31 MPa | 32 MPa | 40 MPa | 64 MPa | 70 MPa |
| Tensile Modulus | 2200 MPa | 2010 MPa | 2180 MPa | 1282 MPa | 1940 MPa | 2770 MPa | 2510 MPa |
| Heat Deflection Temp | 96°C | 98°C | 96°C | 97°C | 138°C | 216°C | 177°C |
| Impact Toughness | 106 J/m | 64 J/m | 128 J/m | 150 J/m | 73 J/m | 41 J/m | 88 J/m |
