3D Printer Parts – Buyer’s Guide
The ‘hotend’ the part of the extruder that gets hot. Makes sense, right?
E3D is a famous hotend, so when in doubt, go with one of those.
Also, remember not to skimp on a bad hotend. After all, this is the heart and soul of your extruder, and the last thing you want to do is get a hotend that clogs all the time or overheats.
Different nozzles are good for different filaments and printer settings. It’s best to get a big pack of many different nozzles so that you always have what you need on hand.
For instance, wood filaments tend to work best with larger nozzles, 4 mm and up. That’s because they contain wood fibers that could clog smaller nozzles.
But smaller nozzles will produce lower layer heights, which might be more aesthetically pleasing. Just make sure to lower the print speed to adjust for the slower flow rate.
Print beds are often heated, which is helpful for working with ABS and PETG filaments. You can buy a heating element and install it yourself.
Also, check out auto-leveling sensors and bed adhesion materials like Buildtak.
It’s very important to have a few good fans working at all times while printing, especially fans for the hotend and the controller. Another fan can be aimed to blow air across the print bed to cool print layers quickly and evenly.
Hopefully, your power supply also has a fan built it, but if not, consider adding one just in case.
Heatsinks are another great way to cool down electronic equipment. Attach them to surfaces that produce heat in order to increase the surface area that airflow from fans can reach.
Heatsinks are surprisingly easy to install but not every heatsink is efficient at wicking heat away from components. Try a few different kinds to figure out which ones work best for your printer.
Obviously a timing belt is necessary to allow the stepper motor to control the extruder’s position. Sometimes they wear out or break when they get old and need to be replaced.
Most of the time, the only thing that really matters is that the timing belt has enough grip on the stepper motor for it function. All of the timing belts below will do the trick.
