These are some tools that saved me a lot of time and frustration building my RepRap. I should have bought some of these tools sooner though! Click image to enlarge. On the left is...

A couple of weeks ago, the day before I was about to give a talk at the Wikimedia conference, I had a small set-back. After changing from electronics platform earlier on, my RepRap machine...

Nederlandse versie: zie onderaan At FabLab Utrecht, a.k.a. Protospace several RepRaps are going to be built (five to start with). I’m supporting the group with advise (and of course encouragement 🙂 ). It will...

What does the RepRap project do? What do they mean with self-replication? Its aim is to design, through the open source process, a 3D printer that can replicate most of its own parts. Currently...

I’ll be speaking on the RepRap at the Wikimedia conference in Utrecht on 1st of November. The programme is in Dutch. See also the www.wikimediaconferentie.nl website

The gears in my acrylic extruder were skipping where there was a moderate amount of resistance given by the drive shaft. Also, because of the distance between the two gears being too big, there...

This is version 0.1 of my reprap controller. I don’t have much time to work on in so I’ll publish it in a non-finished state (then again, what is ‘finished’?). It still needs an...

Something I almost forgot to share is the optical encoder disks. I made those when Chris made his achievement on the encoder. The encoder on the extruder is an important step towards better 3D...

I just visited a conference about the launch of GPLv3. There was a very nice ambience. People I talked with were very interested in the possibility of the RepRap, and about it being a...

In anticipation of new thermoplast extruder parts, I built a Dremel toolhead for my RepRap. It should be able to do light milling, such as PCB isolation routing! I was hoping to do some...

It’s always nice to hypothesize about the future. I think most will agree that nano-technology (as in nanomanufacturing) just isn’t there yet, not discounting ‘smart fabrics’ (nanomaterials) or chemistry for that matter. As you...

Printcrime (Originally published in Nature Magazine, January 2006) The coppers smashed my father’s printer when I was eight. I remember the hot, cling-film-in-a-microwave smell of it, and Da’s look of ferocious concentration as he...

"If I can build a RepRap Darwin, I can build almost any machine." — Me Because of the experience I got from it, and because of the fabrication possibilities it creates. This was one...

That’s too bad. I thought I was almost done. With the 100nF capacitor it worked better. Now I still have the problem that it more or less stops heating in cycles when the power...

More progress, more videos! I had a lot of time on my hands this week, so I almost finished my RepRap! Here are some time lapse videos. Gaining height: part 1 (40 minutes of...

After receiving all those bits (from bytes) I had to postpone my build further because of an exam. That’s done now. I can finally start RepRapping!!! To document my build, it would be nice...

The bits finally arived! Too bad I have an exam tomorrow. This kind of suspense is probably lethal. Anyway, here are some pictures and a small review. I’m really satisfied with the quality of...

A while ago, while I was waiting for the BitsFromBytes stuff, I had to do something. So I decided to tidy the things I already had made. This is the result of the PIC...

This is from a survey among industry leaders in Rapid Manufactoring: "Krailling near Munich, January 28th, 2008: Mass production in the Western world is on the brink of a silent revolution and e-Manufacturing is...

Project RepRap I’ve started building a RepRap. Read more… Also take a look at the website: www.reprap.org What is the RepRap In short: It is a 3D printer capable of printing it’s own parts....
