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. 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. 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 This may impact performance or cause issues.✖ Pure polycarbonate is highly hygroscopic Keep in mind that printing a lot of ASA in an unventilated enclosure can cause the fan shroud and/or extruder plastic parts to deform over time. This will create a wall around the object and keep the model slightly warmer, mitigating the warping. If you don’t have an enclosure, there’s one simple alternative: in PrusaSlicer, set the skirt value as high as possible. The bed should be heated to at least 100 ☌, and the printer should be inside an enclosure to keep a higher ambient temperature. ✖ Partially hygroscopic (absorbs moisture)ĪSA is suitable for outdoor use and for making technical parts. ✔ Possibility of acetone smoothing and gluing ✖ An enclosure is necessary for printing large parts ASA can be easily sanded both wet and dry. Another disadvantage is that ASA releases potentially dangerous fumes during printing - this means you should keep your printer in a well-ventilated area. The main disadvantage of ASA is significant warping caused by temperature differences between the model and its surroundings. This gives the model not only great looks but also different mechanical properties (see our article about chemical smoothing). Another great advantage of ASA is its solubility in acetone vapors, which can be used to make a smooth and glossy finish. See for example our MK3S printer fan shroud. ASA is a tough and resilient material that is, thanks to its UV and temperature resistance (up to 93 ☌), suitable for outdoor use and for making technical parts. Compared to ABS, ASA is more UV resistant, warps less, and doesn’t smell as much. DescriptionĪSA (Acrylic Styrene Acrylonitrile) is a technical material that is considered a successor to ABS. Heatbed: Use the smooth or powder-coated PEI sheet with a glue stick.
