Materials we have in stock:
PLA - Polylactic acid (PLA) is a biodegradable polymer that can be produced from lactic acid, which can be fermented from crops such as maize. PLA is harder than ABS, but melts at a lower temperature (around 180C to 220C), and has a glass transition temperature between 60-65 °C (do not leave PLA parts in temperatures over 60C or 140F).
ABS - Acrylonitrile Butadiene Styrene (ABS) is a commonly used thermoplastic as it is lightweight and can both be injection molded and extruded. ABS is less brittle than PLA and withstands higher temperatures. Its glass transition temperature is ~105C. ABS has a tendency to warp and is not recommended for large, long prints.
PETG - PETG (Polyethylene terephthalate glycol-modified) is a copolymer of PET (Polyethylene terephthalate). PETG has minimal shrinkage and warping. PETG is more strong and flexible than ABS. The FDA has approved PETG for direct food contact and is environmentally friendly and recyclable. PETG is known for its transparency and clarity. PETG has a glass transition temperature of 88C (190F).
PETT (T-Glase) - This material is based on PETT with processing that brings out its reflective properties. T-glase is considered colorless per industrial classifications. It is specifically made of FDA approved polymers for direct food contact/containers and is 100% reclaimable. It's glass transitional temperature is 78C.
TPU - Thermoplastic Polyurethane (TPU) is a soft flexible plastic that retains its shape and form. Below is a list of technical specs for Gizmo Dorks' TPU:
Hardness: 98 Shore A
Elongation at Break: 600% Strain
Tensile Strength: 11600 psi
Density: 1.25 g/cm³
Alloy 910 - Alloy 910 is a Nylon-based polymer with higher tensile strength and more flexibility than PLA, ABS, PETG, and T-glase. It has a glass transition temperature of 90C. However, it has a tendency to warp (requires a several layer brim) and is very stringy, resulting in post printing clean up.
