Research and Development in Self-Replicating Open-Source 3D Printing
Resin filling FFF 3D prints: other people have done this before, but we have never had occasion to try this until now. We had a heavy heat pump that was being installed in an old stable. Stable floors have a slight
[For the latest on this idea, see our documentation here.] This blog post combines three ideas to make a fourth. The three are: The reverse-CT scan 3D printing technique from Berkeley and Lawrence Livermore, The open-source electric 3D scanning technique for
Most recycling streams are not set up to process PLA, despite the fact that PLA is probably the most widely-used 3D printed material and is easy to recycle in a number of ways. This needs to change, and the 3D
How can we correct for every single inaccuracy, non-linearity, bend in an axis slider, error in steps-per-millimeter and all the rest in a RepRap machine using just one technique? Read on… Here’s me, deliberately blocking the nozzle of my RepRap Fisher.
We have designed and made the electronics for our multi-filament drive. It is in the form of an Arduino shield with DC H-bridge motor controllers, opto-sensors and an I2C interface. The I2C means that it will be possible to drive
3D printing with RepRaps is so cool! Two years ago the soap dish in my shower broke (6 months after it was installed…). So I designed and printed one: Today that one broke too (arrowed). But nil desperandum! I just downloaded my
We are developing a multi-filament drive to a single nozzle hot end, as mentioned in this previous post about filament stream merging. It will require an in-line filament guillotine, and we have just finished the first version. This is a
Making RepRap prints stronger without doing a lot of work. The other day a tweet about filling the interior of RepRap prints with more plastic after the print is finished prompted me to look at an old idea of
Inspired by Jo Prusa’s flexible printing bed that attached to his machines magnetically, we decided to do the same for our RepRap Fishers. We got some 10mm x 10mm x 5mm neodymium magnets from eBay, and a 200mm square sheet of
A conventional angle gauge (such as the one above) can’t measure the angle of an object with a sharp corner, because the hub of the gauge is the pin about which it rotates. New 3D printed angle gauge – This
