Avoid jams to print reliably with HTPLA on the Prusa MK3 & e3d hotends

Posted by Alex Dick on

The Prusa MK3 and Proto-pasta HTPLA are an innovative combination, but getting a good result when 3D printing isn't always straight-forward. In this article, we'll share some practices and settings we found to improve reliability when printing with Proto-pasta HTPLA, including our sparkly glitters and metallics, on your Prusa MK3! To avoid jams, we'll focus on removing nozzle restrictions and defining an operating window for a window of opportunity. If you've experienced jams, you'll want to keep reading... First, did you know HTPLA becomes more heat resistant when heat treated? Unfortunately, our MK3 hotend heat break seems to create heat treating conditions at default PLA temperatures. When idle for a few...

Avoid clogs with PLA Composites and all-metal hotends

Posted by Alex Dick on

Does your printer stop extruding on the first layer?  Or does it clog later in a print?  Is your print quality inconsistent with missing cross-sections?   Or does your printer fail on small, intricate cross-sections especially when printing slow? If your extruder gear ever grinds or slips on your filament, you’ll want to read below! Jams and clogs are often from a combination of excessive heat and non-optimal material flow.  This effect is worsened by poorly cooled all-metal hot ends, high torque extruder gears, small nozzles/layers, slow printing speeds, too thin first layer, and excessive retraction. To get more reliable results with PLA composites and all-metal hotends in particular,...

Polishing Iron PLA Prints...?

Posted by Proto Plant on

As I was polishing prints made with our Stainless Steel PLA for the last blog post on wheel polishing, I began to wonder if the same could be done with our Magnetic Iron PLA. After all, it also has powderized metal in it, why hadn't we tried to polish it already?I put this version of the famous Thingiverse owl to the test by attempting to polish it on the bench grinder with a polishing compound. The result was... a slightly shinier owl, but certainly not as impressively shiny as SSPLA after polishing. So can you polish iron prints? Kind of....

Polishing Stainless Steel Prints: Wheel Polishing

Posted by Proto Plant on

For our first post in a series on finishing techniques, we'll be be talking about my personal favorite way to finish prints done with Stainless Steel PLA: using polishing compound and a polishing wheel. What You'll Need: A print made with Proto-pasta Stainless Steel PLA Bench Grinder, Rotary Tool, or Power Drill (if you don't have one of your own, you can likely find it at a nearby makerspace or rent one from a home repair shop) Polishing Compound (we used Fabulustre Cut and Polish Compound) Cotton buffing wheel compatible with the tool you will be using. Since we have a DeWALT bench grinder, we used this buffing wheel)....
