The texture is similar to the Prusa sheets but results in a more porous looking finish on PLA and PETG. On Reddit and Amazon, customers claim that it is easier to print with these sheets comapred to the original Prusa parts. Regardless of which textured sheets you choose, your parts will look far more professional with a textured sheet than regular smooth sheets, but some added care is needed:
Use 90%+ isopropyl alcohol (IPA) to clean after each print
After 10-20 prints, consider rinsing with mild dish detergent and warm water, then dry and wipe down both sides with IPA again.
When releasing larger PETG prints, allow the part to fully cool to room temperature, then consider heating foir a few miniteos prior to releaseing the print.
For trickier PLA and ASA prints that tend to warp or dislodge, it is OK to use PVA gluestick to fill in the gaps on the texture. This will help the print stick and release when finished. Note that the texture of the part will look a little weird and there will be white residue on both the part and the sheet which you'll need to clean off with warm water.
Cost: ~$30-40
Install: 2 seconds
Ever get blobs of filament sticking to the nozzle? Or have a difficult time keeping the extruder at a constant temperature when the part cooling fan is on?
Put a sock on it!
These little beauties just clip onto the heat block and keep everything clean and at the proper temperature. They don't last forever and will eventually crack or deform from so many heat-cycles, so best to keep a spare.
Cost: ~$2 each
Install: 1-5 minutes depending on which part cooling shroud you have installed
In case you want to use a V6 nozzle on the Nextruder, install it together with this nozzle adapter.
Cost: ~$30
Install: 20 minutes
An enclosure helps to maintain a consistent air temperature around the printer resulting in more reliable prints for PETG and ABS. It also reduces noise and smells. You will need to cut a small hole to pass the power cable through.
Cost: ~$30-40
Install: 5 minutes
Spare Parts
Some printer components wear out so it's best to have a few spares:
