If the Easter Bunny had a RepRap… 0

…i’m sure he would print an eggbot (or two). Just in time for this year’s Easter i finished building a copy of Glasswalkers Revised Fully Printable Eggbot from surplus parts i had lying around – an Arduino, a pair of discarded Steppers from my RepStrap, “EasyDriver” Stepper Drivers and a small servo. The Arduino is running [...]

Gyroid Vase – beautiful Math Art 0

Thingiverse user Dizingof recently postet a host of beautiful Math Art that is very well suited for 3D printing. I must say the model below is generating exceptionally pleasant sounds when printing (mostly just perimeters and organic shapes).   Gyroid Vase 2012 – By Dizingof (50% smaller, with base) by garyhodgson

RepStrap on a diet: losing weight! 1

Over the last two months our RepStrap has undergone some serious upgrades to improve both print quality and speed. Meanwhile, one can hardly call this a RepStrap anymore considering its self-transformation into an even more Prusa Mendel look-alike. The first part of the upgrade also caused the most noticeable effect on printing performance: Losing weight. [...]

Household repairs: fix a broken aquarium filter 2

Last night I moved my goldfish aquarium to my new home. During reassembly of the pump a small clip that secures the sealing bracket on my “EHEIM eco pro” aquarium filter broke. I had to quickly fix this since the fishes were waiting in their transport container and urgently needed some fresh and circulated water. [...]

RepStrap’s first child – another RepRap family tree 0

We have reached another milestone in our RepRap Projekt. Our RepStrap finished printing its first child. The Prusa Mendel v2 is assembled and working. Last two challenges had to be overcome: Because the RepStrap still has no heated printbed the Prusa x-carriage had to be made from PLA. Which is not the best choice when [...]

Replication almost complete 0

Our RepStrap nearly finished printing all neccessary parts for its first child, a Prusa Mendel v2. Only the Extruder is missing. Yesterday Jonas made a short video of the RepStrap printing. The Printer should primarily serve the purpose to make a ‘real’ RepRap-Prusa from printed parts. Since I managed to get reasonably useful (and mechanically robust) print results, step by step set of parts for a RepRap-Prusa was completed. Further calibration and optimization of [...]

Already printing! 1

Well, that’s awesome. I have never seen a 3D printer live before – and now this bootstrapped contraption on my desk is fabricating three-dimensional objects from plastic. Absolutely fascinating. Time passed quickly last week, so i’ll try to give a brief summary of the final steps to a working RepStrap 3D printer. When our RAMPS-board [...]

My way into 3D printing 1

It must have been about a year ago that I (again) stumbled across the RepRap project. If you ask Jonas, this was probably the key moment, when it grabbed me to build my own 3D printer. Since I can remember we have dreamed up technical projects together that failed to realize due to an absence of a full featured mechanical workshop. But being able to make free-form objects from plastic right on the desk, that changes everything. A few months later I had read deeply enough - and Jonas infected. We started [...]
