Here you will find some upgrades we use or have developed for our printers.
The first and one of the best upgrades you can do is install a heated bed. Traditionally it is only needed for ABS or other high temperature materials but in my experience it is a big help with PLA as well. Combine it with a layer of Kapton tape and you have a smooth surface where the PLA really sticks to but, when cooled down, is easily removed.
Heated beds are available for all our printers.
