Vik Olliver is doing micron-scale #RepRap #3D-printing! “This degree of accuracy was initially made possible by 3D printed microscope platforms designed by The #OpenFlexure Project.”

on 02021-12-08"Snappy 3", “an Open Source RepRap 3D printer designed by RevarBat from July 2014 to January 2018. It is a true RepRap, using very few non-printed parts. This design needs no belts, pulleys, metal rails, and almost no screws other than to mount parts to the motors. This means that you should be able to put one together for about $216, including the price of plastic to print parts. The entire thing snaps together, and you should be able to assemble it from parts in only a couple hours. The few required non-printable parts are available world wide from a variety of suppliers.” #self-replicating #RepRap #3D-printing
on 02021-12-08"Mulbot", open source mostly printed 3D printer “square rail type 3D printed housings for linear bearings. Since the bearings and rails are printed they have been integrated into the frame members. 4.5mm G100 Stainless Steel bearings balls are used to recirculate through the bearing housings to reduce fiction and to provide preload to remove bushing slop. All three of the printers drive systems are 3D printed as well. The Y-axis is driven by a 3D printed herringbone gear rack and pinion. The combination of 3D printed drive and idle pulleys and a TPU belt drive the X-axis hot end carriage. While the Z-axis utilizes 3D printed trapezoidal lead screws and nuts to translate the hotend vertically.” #3d-printing #self-replicating #RepRap

on 02016-01-11The "Snappy" #RepRap #3D printer, by Revar Desmera (revarbat).
on 02016-01-11The #Snappy #RepRap #3D printer can “self-replicate” itself in 100–130 hours and two kilos of plastic, according to one of the comments here. #self-replicating
on 02016-01-11The 2014 CoreXZ #RepRap #3D printer uses an anti-racking arrangement of fishing-line pulleys to run its X and Z axes: differential for X, sum for Z, with a mechanical-advantage division by 3. This keeps all the heavy stepper motors off the moving part of the machine.
on 02015-12-28#Snappy is a #RepRap #3D printer that snaps together out of almost entirely 3-D printed PLA parts, with cable chains and linear rails and whatnot. No non-printed belts, pulleys, or rails, and almost no screws. Still uses a metal threaded Z-axis, metal motors, a glass build plate, and a metal hotend.
