If you are looking for a fun and exciting 3D printer to build that requires a bit more technical skill than our i3 kit this delta printer might be just what you are looking for. This delta style printer is constructed using 2020 extruded aluminum rails making it strong as well as aesthetically pleasing. This printer also comes with an auto level servo that will set a relative bed level without you making the physical adjustments to the bed. All in all this is a great kit and worth the time required for this slightly more demanding setup.

This is a kit of components for assembly into a 3D Printer by the end user. Building and using the printer is potentially very dangerous as it involves electricity and high temperatures.

Building the printer will require a certain amount of physical dexterity, common sense and a thorough understanding of what you are doing. We have provided fully comprehensive build documentation to enable you to build your Folger Tech 3D Printer Kit in a safe manner.

However ultimately we cannot be responsible for your health and safety whilst building or operating the printer, with that in mind be sure you are confident with what you are doing prior to commencing with building or buying. Read all of the manual to enable you to make an informed decision.

Building and operating involves electricity, so all necessary precautions should be taken and adhered to, the printer runs on 12V supplied by a certified power supply, so you shouldn't ever have to get involved with anything over 12V but bear in mind there can still be high currents involved and even at 12V they shouldn't be taken lightly.

High temperatures are involved with 3D Printing, the Extrusion nozzle of the hot end runs at 230°C, the heated bed runs a 110°C and the molten plastic extruded will initially be at around 200°C, so special care and attention should be made when handling these parts of the printer during operation.

Do not leave your printer running unattended. We cannot be held responsible for any loss, damage, threat, hurt or other negligent result from either building or using the printer.
