Welcome Ethopia!

Thanks to work done by TReND Africa, André Chagas and his crew from the University of Tübingen Werner Reichardt Centre for Integrative Neuroscience, and funding from Volkswagen Stiftung,  the first-ever 3D printer workshop in Addis Ababa just concluded and they built none other than MOST Delta printers! Great work and […]

openSCAD in Our High School Classroom

Our mathematics curriculum introduces students to concepts like union, intersection, vectors, translations, and rotations. Using OpenSCAD in conjunction with the  MOST Delta RepRap 3-D printer in our classroom provides opportunities to clarify and reinforce these concepts while also highlighting an out of classroom application. The script writing intimidates students at […]

Unplugging a 3-D Printer Nozzle

Eventually, everyone suffers a plugged nozzle. Contaminated filament, a stray PTFE shaving, maybe even dust bunnies (maybe?) get jammed up in the nozzle, making one’s life difficult. There are two types of plugged nozzles: totally occluded with nothing getting past it and partially blocked where just a very thin strand […]

Slic3r revisited

I started using Cura a couple years ago after having significant problems printing a particularly difficult object sliced with the then-current version of Slic3r. Every once in a while I check back in on Slic3r to see how things have progressed, and this latest experimental version is looking very good, […]

Live-feeding New Filament – Updated Extruder Drive

The new extruder drive design is now available at the MTU-MOST github repository. Only slight modifications were made, most were to improve performance when live-feeding new filament, but I also replaced the button head screw with a socket head screw (the button head screw will still work, though). As demonstrated […]

Fifty New MOST Deltas at Michigan Tech

Michigan Tech posts a nice image on their landing page of the students enrolled in MY4777, who completed assembly of their very own MOST Delta RepRap 3-D printers: Nice job, all!

Hybrid slicing with Cura

There are times when I want to change some aspect of slicing at a certain height in a print, like increasing infill where there are nut pockets so that the nuts don’t spin and/or break the print when I tighten the set screw.  The TweakAtZ Cura plugin permits some adjustment, […]
