I liked the idea so much, Elf #287 was promoted and is now lead manager in charge of all replacement printer parts soon to be hitting our Etsy shelves! Stay Tuned.Īll parts are printed using Prusa stl files and follows the recommended printing specifications of 0.2mm layer height with 20% infill. PC is even stronger and has better impact properties when compared to ABS.Įlf # 287, who was working with me and Elf # 256 to replace this ailing part, suggested we list this part for other makers who may need to bring their trusty Prusa printer back to spec. But, I did have a some ABS and Polycarbonate (PC). The original piece from Prusa was crafted from ASA due to its high melting temperature, limited odor while printing compared to ABS, and low warpage. The Prusa has continued to melt delicate filament into spectacular creations. The printer has been a steady workhorse even through the injury it sustained during the dreaded incident of June 2020 involving elf #256. If you print with polycarbonate regularly, we still suggest using glue stick to keep your satin sheet in the best shape possible.Alas the time had come to replace a piece of our beloved Prusa i3 MK3S printer - the fan shroud □. This surface doesn't need any separation layer if you print with PC Blend occasionally. This issue was moderated with the powder-coated satin sheet. If you print without a glue separation layer, you risk damaging the print sheet. PC Blend is printable on the powder-coated TXT sheet if you apply glue stick on it. Recommended nozzle and bed temperatures are 275☑0 ☌ and 110 ☑0 ☌. Prusament PC Blend is easy to print compared to other polycarbonates. This typically occurs with ambient temperatures below 18 ☌ when the printer cannot hold the high heatbed temperature. In some cases, the printer might show a “Bed thermal runaway” error. A lesser number of perimeters increases the chances of a successful print of large polycarbonate models. Denser infill (and more material inside the object in general) increases warping - and a risk of separation from the print surface. Warping is also affected by infill density and the number of perimeters. Prints with round edges warp less than those with sharp edges (this is true for any type of filament). Polycarbonate is not suitable for printing large objects covering the whole sheet. ![]() You should use the Brim function for printing parts with a small contact area with the print surface. This will make a microclimate with a slightly higher temperature around the model and increase your chances for a successful print. I thought it would be a good opportunity to replace it with an improved design. I figure a good option is to actually print a fan in nylon-cf. If you don’t have a printer enclosure, we suggest placing the object in the middle of the printing platform and setting the skirt value as high as possible. (sverzijl) Active Member Best part fan shroud After doing a project that has involved printing lots of nylon-cf composite my fan has started to droop. It is also possible to make your own enclosure. You can purchase the Original Prusa Enclosure in our e-shop. However, this is not recommended for large prints, where we recommend reducing this. For small to medium objects, you can increase infill to >25% and add more top layers (4 or more) for a stronger print. Polycarbonate needs to be printed on a special surface, for example, a powder-coated sheet with a glue stick, PEI, or Build-tak. Printing polycarbonate is often tricky, as it tends to warp a lot, even with the additives. The best use of PC is for printing technical parts requiring great heat and mechanical resistance. ✖ Application of a separation layer is recommended ✖ High warping, especially with large models ✔ High impact tenacity and tensile strength ✖ Pure polycarbonate is highly hygroscopic
