Tropical Labs, a Washington-based lab specializing in custom electronics and noted by the Mechaduino project, has unveiled yet another development - a 3D printer from a coffee maker. The design of the printer is based on the kinematics of the delta robot, and in its original form - as intended by the inventor of the delta robots, Raymond Clavel in the distant 80s. Unlike conventional delta printers, this design does not use guides. Generally.
“There are dozens of designs of homemade 3D printers available on the web, but almost all of them require precise guides and bearings. Most printers need two guides and at least three linear bearings on each axis, that is, about six guides and 9-12 bearings. Even the so-called "delta printers" usually use linear drives that require a similar number of guides and bearings. It is these precision elements that determine the balance between cost and accuracy of a homemade 3D printer, ”the developers say.
Design by Tropical Labs uses a rotary drive. Taking the coffee maker as a basis, enterprising inventors got a good chassis with a ready-made heated platform.
As for the firmware, the creators used a modified version of FirePick Delta Marlin. The great thing about the design is that before starting 3D printing, you can treat yourself to a cup of drink: “You don’t have to redo the coffee machine itself, so you can always remove the print assembly and make coffee!” Whether the design will be monetized is not specified yet, but in any case, the project will remain publicly available.
