Interpretation.

Arguably, our biggest power is the ability to choose how we interpret things. Given the recently unfolding events in the Israel-Palestine conflict, jumping to quick conclusions and rushing to judgement is as common as...

The dirty secret of coal plants

Sorry for for the click-bait title. There is not actually a secret, it’s been known for a long time that coal plants emit a lot of dirty substances besides the problem of greenhouse gases....

Tesla 2022Q1 🚀🌕

Het gaat inmiddels ECHT goed met Tesla. SpaceX gaat met Starship letterlijk naar de maan, maar bij Tesla-fanatiekelingen is de meme “To the moon” populair. Ondanks supply chain disruptions (o.a. door COVID en de...

New projects!

Since 2018 I’ve been less involved with Ultimaker, the company I ran with my co-founders. While I really miss the amazing people there and the vibrant atmosphere, Ultimaker has “grown up” to a point...

Ultimaker op Tegenlicht!

We were lucky to be featured in Tegenlicht. Tegenlicht are exceptional documentary makers who go in depth into major issues of humanity. The part where I’m being interviewed starts at around 34 minutes. Most...

Google Glasses have arrived!

Now for something that’s not related to 3D printing (well, not directly), but so insanely cool that I have to blog about it right now (no, this can’t wait another day)! Through a friend...

Ultimaker @ Codebits 2012!

ReplicatorG’s build volume

Update: Phooky merged this improvement into the official branch, thanks!! There was an issue with ReplicatorG posted a while ago: The stl preview pane seems to be fixed at 10cm x 10cm x 10cm....

RepRap and ReplicatorG-5D

Some things are just no fun, and in a project driven by volunteers, these parts tend to be neglected. Making things user friendly doesn’t help yourself, because when you get to the point where...

Another non-printed part less

I just made a serendipitous discovery:I printed a very narrowly fitting freely rotating Bowden coupling and it had such a good grip on the PTFE that I printed another with just a little more...

Wedding slideshow

Our wedding day was really unforgettably beautiful: Below is my original post about “the making of the cake topper”. It stood there perfectly because my best friends made a gorgeous cake (such a great...

Erik’s RepRap for loan!

In December last year, I became the proud new owner of Leo (after Leonard Darwin), the son of Charly (Charles Darwin (my earlier machine)). It didn’t take 9 months to fully develop, but it...

RepRap in Dutch newspapers again

A while ago I put on my RepRap ambassador hat again which resulted in a newspaper entry in a Dutch newspaper. Since it’s slightly old news now and I’m allowed to cite works that...

Meta-innovation: Surprise boxes!

What I really like about the Thingiverse physical object repository is that people are not just adding awesome, innovative [1, 2] and useful [1, 2] new content. They also innovate in how they publish...

RepRap Survey

Are you operating or building a 3D printer? (RepRap, Cupcake CNC, RapMan, etc.) We still need some more responses for the data to be statistically significant. So if you have not done the survey,...

Mini-mendel printed!

From Erik's RepRap parts For some, the fact that the mini-mendel isn’t a finished product is a reason not to try it. For me, it’s the opposite. I’ve now printed all parts for the...

RepRap made the Dutch newspapers!

RepRap got coverage in a well respected Dutch newspaper, NRC.next. They also made a blog post with an interview, the original post is in Dutch, but here’s a (poor) google Translation to English. The...

Smooth I am, yes…

You think vanity and Yoda do not go together? The force may be strong in this fella, but he used a very powerful scrubbing lotion to make him look much younger. 🙂 Stratasys sent...

Accessories evolution: Spindle holders!

Even things that are peripheral to the RepRap and makerbot are going through some remarkable evolution! It not that strange, because they can really make life a lot easier. Some accessories, like spindle holders,...

Banning 3D printers?

Nick Jones from Gartner made an interesting remark: “[A]s one of my clients pointed out yesterday, do we really want an affordable domestic fabber? Fabbers will likely “print” objects using some form of plastic....

RepRap @ NPOX 2009, Hilversum

We demonstrated the RepRap at NPOX (15 nov. 2009). It was in the “Beeld en Geluid” building which was a huge building, but beautiful at every scale. We were positively surprised by the way...

RepRap Day @ Protospace

The RepRap Day at Protospace (14 nov. 2009) was a great success. (see also, more pictures by Bas) The plan was to print an entire machine at the event, but we did more talking...

Support material, part two!

In the previous post, I described the rationale for adding a support material capability. It’s not needed for every object, but to have consistent results with tight tolerances, for many objects you cannot do...

The quest for support material support

In general, there are three general methods to making objects. Formative: By (de)forming matter, such as bending a metal beam into an angle. Or a big steel sheet into an enclosure, or making a...

Many RepRap Parts printed!

I’ve been working on getting production up. Because I’m going on a holiday I guess I’ll show of the results 😉

Phun simulations with RepRap

This is a simplified simulation of the mechanical “Cartesian bot” of The RepRap. It allows you to play with things like play (a.k.a. backlash), tension of the belt that drives the axis, etc. You...

RepRap at Reboot 11!

After Siert spent 5 minutes in Rhino CAD software, we had a printable model. The picture shows the bracket being printed. Installed on the WiFi bike Being at Reboot 11 was amazing. The theme...

In the group at Protospace (FabLab Utrecht, the Netherlands) we designed and built a new extruder. Most of the design work was done by Robert, and a very good result was obtained with the...

Personal Empowerment

I personally think that the RepRap is a tool of personal empowerment. It allows you to take matters into your own hands. Are you not completely satisfied with some object that you use? You...

RepRap network effects (draft)

The exact topic is still preliminary, but my masters research is going to be on user innovation in fabrication and its interrelation with the commercial players, their products and their customers. The creation of...

[NL] Presentatie: Introductie tot de RepRap

Giving your RepRap a voice!

Debugging sucks… I’m (re)building my machine, and one thing I’m missing is transparency. We’re adding layers to keep complexity manageable, but inevitably some transparency is getting lost along the way. There are several interfaces...
