We have viewed this funky twin disk polar printer already not too long ago, but [Heinz Loepmeier] has been busy working on it, so here’s an update. The key target below is nozzleboss, a blender plugin which allows the floor textures of currently sliced objects to be manipulated. The strategy is to study in the gcode for the object, and transform it to an inside mesh illustration that blender needs in purchase to operate. From there the desired textures can be applied to the surfaces for subsequent phases to function upon. One particular trick that nozzleboss can do is to build pounds maps to tweak the extrusion flow price or print velocity worth according to the pixel price at the area — these kinds of ‘velocity painting’ can deliver some pretty delicate surface consequences on earlier featureless faces. An additional trick is to use the identical bodyweight maps and just map colours to blender textual content blocks which are injected into the gcode at export time. These gcode blocks can be used swap device heads or extruders, enabling mixing of several filament colors or varieties in the similar object.
Some pleasant examples of these kinds of printing manipulation can be found on [Heinz’s] instagram page for the project. So, heading again to the hardware once more, the to start with movie embedded beneath reveals the ‘dual disk polar printer’ fitted with a nuts five-extruders-into-just one-nozzle mixing hotend setup, which should be capable of complete CMYK colour mixing and some. The 2nd video below displays an intriguing by-item of the wide horizontal movement array of the device, that the complete printing region can be shifted to a nozzle at the other stop of the gantry. This allows a novel way to change extruders, by just relocating the complete bed and print less than the nozzle of curiosity! A single remaining observation — is that of the print floor — it does search instead like they are printing direct onto a slab of marble, which I consider is the to start with time we have viewed that.
Fascinating printer models are staying worked on a great deal these days, here’s a really good 5-axis prusa i3 hack, and if you want to remain in the cartesian earth, but your desktop device is just way too small, then you can often supersize it.
