Materials Info

Here is information about the 3D printing materials I offer and the colors I currently have available.

PLA

Colors: White, Silver, Black

PLA is the most common and easiest to print 3D printing material. It is a bioplastic made from renewable resources such as corn starch. PLA is the most rigid of the materials, but also the least temperature resistant, as it begins to soften at temperatures above 60°C. PLA prints may deform if left in a hot car.

PETG

Colors: White, Gray, Black, Translucent White, Translucent Blue

PETG is a modified form of PET, the plastic commonly used in water bottles and other packaging. A versatile material, PETG is more flexible than PLA and has a softening temperature of 80°C. PETG is naturally clear, which allows the use of transparent filaments (printed objects are not transparent but only translucent, because tiny voids in the object scatter the light).

ABS

Colors: Gray, Blue

ABS is a common plastic used in many consumer goods, such as Lego. It has high toughness and can withstand temperatures up to 100°C.

On large prints, ABS is prone to warping, a phenomenon where the edges of an object curl up due to thermal contraction of the printed layers. I have a heated enclosure for my printer to reduce this effect, but it can't always be eliminated.

ABS is soluble in acetone. It can be solvent welded, or smoothed with the "acetone vapor smoothing" technique.

ASA

Colors: Black, Dark Blue, Natural (off-white)

ASA is a plastic with similar properties to the more common ABS, but with improved resistance to weathering and ultraviolet light. It is widely used in the automotive industry, and is suitable for outdoor applications. ASA withstands temperatures up to 100°C.

ASA is prone to warping, similar to ABS.

Like ABS, ASA is soluble in acetone.

TPU

Colors: Black

TPU is a flexible, rubberlike polymer. This material is often used in soft phone cases (not the silicone kind). I have two varieties, one with shore hardness 91A and one 80A. The 91A version is harder, smooth to the touch, and shiny, while the 80A version is softer, feels rubbery, is matte, and is lighter (it floats on water).
