A 3D Printer With Quadruple The Output

Although the polygraph is colloquially linked with pseudoscientific lie detector tests, the real creation of the initially polygraph was intended to mechanically replicate the pen strokes of an individual crafting. Famously, a polygraph was utilised by previous US President Thomas Jefferson in his “modern office”, a duplicate of which still sits in the Smithsonian museum. Handful of of us have a need for a pen-based polygraph any more, but inspiration from the centuries-old creation can still be gleaned from the equipment, like in this 3D printer which can output four identical prints at once.

The printer is a Main XY style with four different print heads, which are all locked with each other. The printer behaves as if there is a solitary print head which keeps it simpler than it or else could be. Some more thought demands to be compensated to the print mattress to assure it’s degree and flat, and it also consists of a special Z-axis designed to stop Z-banding from poor high-quality leadscrews. It has a fairly large print location, but a apparent restriction is that it’s fundamentally quartered, so whilst it can create lots of pieces at as soon as, it can’t produce a single aspect that makes use of the entire space of the print mattress.

Every single printed element made use of to make this printer was built by [Rick] in OpenSCAD. He also created a custom electronics board with the printer drivers, and all other related circuitry in KiCad. For any individual who prints large volumes of pieces, this might be just the trick to raise output without having getting to control extra printers. If you already have extra printers and require an a lot easier way to control them all, choose a glimpse at this dedicated Raspberry Pi established up to do just that.
