A new sample spool for your filament sample coils

Posted by Keith Kovala on

For our first subscription filaments we recommended the use of the MasterSpool to hold the filament in our posting Effective Loose Coil Handling for a Positive Experience. This was primarily due to the core size we use on our spools. It may not be well known, but the center core of our spools are larger to provide a better extrusion experience. Spools with a smaller core size result in filament having to bend more to get through the extrusion path. This bending back of filament often results in breakage in the extruder.  To avoid this negative experience we use a larger...

Effective Loose Coil Handling for a Positive Experience

Posted by Keith Kovala on

Loose coils can easily become tangled, but don't be discouraged. The key to a positive coil sample experience is control of the ends. Just like letting go of the loose end on a spool, letting go of the ends on a coil can quickly turn the loose coil into a messy knot.Step 1 is to identify the head and the tail of the sample. For our subscription coils, we use a rubber band to retain and isolate both the head and tail ends. The head is on the outside of the coil while the tail comes from the inside of the coil...

Leveling Up your Print Game on the LULZBOT MINI

Posted by Gabe McGaffey on

At Proto-pasta we spend a lot of time understanding how our materials interact with different slicers and printers and by doing this we hope to help you achieve the best printing experience possible with the unique filaments we offer. We recently analyzed the Proto-pasta High Temp PLA profiles provided by Lulzbot available on Cura Lulzbot Edition to see how Proto-pasta HTPLA will print based on the pre-made settings. This blog is written to shine a light on how volume flow rate plays a significant role in printer capabilities as well as walk you through a brief explanation of the steps...

Intro to Tuning: Carbon Fiber on the Ultimaker 2+

Posted by Gabe McGaffey on

First time using Proto-Pasta Carbon Fiber HTPLA? Or maybe you've already discovered this excellent material and want to improve your printer's performance? It can be challenging, but with these tuning techniques and a little patience, you will be able to print stronger, more accurate, and precise parts.  The typical consumer 3D printer is a very complicated process packaged in a friendly-looking machine. Although we wish that achieving the advertised results was as simple as just hit "print!" unfortunately, It's not :( What we are shown can be misleading because as soon as your printing experience doesn't go how you envisioned it, it's easy to give...

Nozzle replacement for Carbon Fiber or other abrasive filaments

Posted by Alex Dick on

When suggesting Carbon Fiber as a 3D printing material, nozzle wear is often the first concern. While it's important to be aware of nozzle wear, don't let it stop you from enjoying the benefits of heat-treated Carbon Fiber HTPLA. In the following article, we'll show you how to identify, replace, and adapt your 3D printer's nozzle to changing conditions. By the way, you can absolutely use a stock, brass nozzle to print carbon fiber. It works! Will the nozzle wear more quickly than a harder, wear-resistant nozzle? Sure, so let's prepare you to replace your nozzle for printing with abrasive materials. Nozzle replacement doesn't have to be...
