Printing complex models usually requires support material, and sometimes models even need support inside the object and in hard to reach places. Enter Polyvinyl Alcohol, a water-soluble support material that dissolves away in a water bath to leave only your perfectly printed part. PVA is a perfect match for PLA, since they share a very similar printing temperature and are both very easy to print.
The hotend is the component of a 3D printer that melts the filament for extrusion. A crucial part of successful 3D printing is maintaining consistent and accurate temperature.
The nozzle is the component of a 3D printer that deposes the molten filament out into the build area.
The extruder is responsible for feeding filament into the hotend and out of the nozzle. Having a strong, reliable extruder is vital to accurate, high quality 3D prints.
A clean and well adheared first layer is critical to successful 3D printing, and much of that success or failure comes down to the build plate used. From borosilicate glass to BuldTak, it's all here.
