This is a short list of current projects.
Summary: The Gunstrap is a plywood based repstrap that is constructible with only basic tools and can use parts obtainable from old domestic printers and scanners. Its key difference to other repstraps is its sealed heated chamber designed for use at 70C to 100C.
Current Status: Designed Finished and about half built.
Summar: A granular extruder takes bulk granular plastic and extrudes it into a filament suitable for use with a 3D printer.
Current Status: First Attempts were unsuccessful. Basing the new attempt on the web4deb extruder. Parts ready to go, just need to assemble.
Current Status: Printing objects with ice has been proven to work (see icerap wiki page) by a number of university groups. However doing it with out placing the whole printer in a freezer has not been attempted as far as i’m aware.
Mantis PCB Mill
Summary: The Mantis Machine 9 is a DIY PCB CNC designed by David Carr.
Built and working. Stripped for parts for the gunstrap. Will be rebuilt with smaller geared stepper motors for high precision 3D printing and PCB milling.
Dual Wade’s Geared Bowden Extruder.
Summary: The idea is to take the well known Wade’s geared extruder, re-model it in sketch up so that its a dual extruder and add some brackets so it can be used as an external Bowden extruder on the Gunstrap. It now also includes a Herringbone gear set.
Current Status:A work in progress.
