Hardanger Fiddle uses HTPLA-CF for Stiffness and Style

Posted by David Perry on

HTPLA-CF opens new possibilities in 3D printed violin design and construction!  It's a bold claim, but I'll stand by it. We don't quite have the data for me to claim that HTPLA-CF is magically eliminating creep for all time, but annealed HTPLA-CF is leaps and bounds past any other PLA based filament in terms of long term performance and reliability. I'll stand by it by pouring way too much labor into making this beautiful instrument -- a 3D printed Hardanger fiddle. Spoiler alert, it worked! You can purchase the Modular Hardanger design/print files here. [This blog is guest posted by David Perry, lead...

Using Heat Treated Carbon Fiber HTPLA for the Prusa MK3 R3 Extruder Assembly

Posted by Keith Kovala on

Many times when printing extruder assembly parts for a 3D printer, like the R3 extruder upgrade for the Prusa MK3, PETG or ABS are specified as the material to use due to the heat exposure. However, Carbon Fiber HTPLA works great in these cases because of the carbon fiber's ability to hold form (rigidity), printed part detail, and heat resistance. Add to that the beautiful finish of 3D printed carbon fiber and even a function-before-form guy like myself gets excited. So where does HTPLA's heat resistance come from? It comes from it’s semi-crystalline structure. Amorphous materials like PETG and ABS surrender their stiffness (and...

Filament Testing Grips & Replacing Machined Parts with Carbon Fiber

Posted by Gabe McGaffey on

Replacing traditionally machined parts with 3D printed ones sounds like a far-fetched idea, but is it? Subtractive technologies like CNC milling have long been taken seriously in creating functional parts for consumer hobbyists to large-scale industrial manufacturers but additive manufacturing's cred and capabilities are catching up. With advanced materials available for 3D printers like Proto-Pasta’s Carbon Fiber HTPLA, the applications for 3D printing have expanded to include more functional use.  At Protoplant, we create custom solutions to provide the best possible 3D printing experience to our customers. Our most recent addition to our shop floor is a tensile strength tester that we call Thwing (below). Thwing...
