PLA is commonly known as a glossy, shiny, plastic that is well suited for 3D printing. As the field of filaments continue to expand, new filaments come to market to provide more artistic options to 3D printers.
I printed some prototype fidgets for an upcoming fair with matte finish HTPLA. The filament printed perfectly at 225 C, with a smooth print quality that I have seen with other Proto Pasta filaments.
Matte fiber does have a rougher surface texture than glossy PLA, which is something to consider when using this filament. I was surprised by the texture, which is about as rough as wood based composite filaments. This texture may limit this filament from some applications that require a smooth surface like moving parts, or lost PLA casting molds.
Matte finish HTPLA has wide artistic appeal for 3D printers that want to add different finishes to their prints. According to Proto Pasta the texture, color and sheen can be altered with your printer settings. I’ll have to play with them more to see what kind of sheen and textures I can get with this filament in the future.
Like the aromatic coffee HTPLA, this can be heat treated (annealed) to be stronger than standard PLA. Heat treating may also change the visual properties of the print, but I did not test that for this review.
Matte finish HTPLA is part of a growing line of PLA blends from Proto Pasta. This blend is good for artistic and general purpose prints. Matte finish HTPLA can be dual – printed with glossy filaments to provide more color contrast, or printed alone to make your prints stand out from all the other your other shiny prints.
DISCLAIMER: Proto Pasta provided the samples to 3D-PT at their own expense, with no expectations given for this review.
