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 of it is in English, but our interview is in Dutch, possibly there will be a translation/subtitled version made available.
The documentary displays an optimistic view of the future where global energy, food, healthcare are abundant and affordable, and even physical goods can be manufactured on the spot in your own home.
"The the rate of innovation is a function of the amount of conversations that are going on."
- Peter Diamandis
3D printing democratizes the ability of ordinary individuals to create physical solutions, to solve transportation problems by never producing more stock than is used, to produce more personal objects and efficiently, with much less waste. The future is here! I'm thankful that we get this opportunity to have so much control over the physical things around us, and the ability to go from your imagination to a real thing, in minutes!

Big News: Ultimaker is now selling ... Posted by Erik de Bruijn in RepRap, Ultimaker at 22:47
I'm really excited that our company has just started offering fully assembled Ultimakers in addition to the kits!!
Don't worry, we won't drop the kits from our offering any time soon! We're still great supporters of the hacker community. Also... we keep on innovating and won't leave early customers with a 'legacy machine' empty handed. Specifically, we provide the opportunity to upgrade your Ultimaker to make sure you enjoy the benefits of those who bought the latest version of the Ultimaker. We've done this through upgrades such as the UltiController, the new Hot-end, an extruder drive upgrade, etc.

Ultimaker @ Codebits 2012! Posted by Erik de Bruijn in RepRap, Ultimaker at 22:19
At Codebits, an amazing event organized by Sapo (an awesome, innovative Portugese company) a lot of nice stuff was happening. Besides a 48 hour programming contest, there was a hardware hacking den. This is where I met Mitch Altman again and lots of cool Portugese people who were making awesome code and awesome things! Also had a nice talk with Rob Bishop, a smart and down-to-earth guy who revolutionizes computing by making the Raspberry Pi into a global hit 'from the comfort of his bedroom'.
See my Google+ footage of the event here...
Besides printing stuff that people designed all throughout the event, I also gave a talk and several workshops on how to 'code pysical objects'. A recent development (found after the talk) that I'm really excited about is CoffeeSCad! You should check that out, too!
For a video of my talk, have a look here or click the image below.
Again, I'd like to thank the many volunteers, in particular Pedro! He and his many friends made the visit to Portugal a very nice one. Also, Celso, who was main instigator of the whole Codebits experience, which really is something to whiteness before you believe it! It was also amazing to meet Nelson Neves and Dini Miguel who were doing awesome projects of which I'm sure you'll learn more.
Ultimaker was proud to be listed among the the sponsors of the epic Codebits 2012 event!
For those of you who know your Portugese, Ultimaker was mentioned on TV station RTP, here.
Can't wait until Codebits 2013 arrives!

Trip to Switzerland Posted by Erik de Bruijn in RepRap, Ultimaker at 13:00
Beautiful view of the river in Bern
With al the busy-ness at Ultimaker I haven't traveled much. Finally I had a nice trip to Switzerland, to give a talk and meet our friends from the FabLab Luzern, who also give workshops in building the Ultimaker.
I met Roman Jurt in real life and he showed me the FabLab, and added UltiControllers to their Ultimakers. He showed me around Luzern, Zurich and Bern.
Later I met Ramun Berger, also FabLab manager and director of 89grad in Bern. These are great guys doing very interesting stuff, and sometimes they open up their company's workshop to be a FabLab. They have two Ultimakers in the lab and used it to make some really nice prototypes for their customers. One of the 89grad-lab visitors, Thomas Staub, was working on a quadcopter for his employer, DFRC.
It was nice it see how 89grad works on very diverse but innovative projects and how they open up their lab to others!
Later I had the opportunity to give a talk at "schule für gestaltung bern und biel-bienne" or the design school of Bern/Biel. The subject was mass-customization (slides here). The subject isn't my expertise but I had read a whole shelf of books which touch upon the subject, so I could give good examples. Also, I put it into practice by printing bracelets with the visitor's names on it. It was a funny surprise to see my name on posters around the school's main building and to see that the press was attending the talk. It's great to see the subject will become better known in Switzerland, and this may contribute to it.
Thanks Marc Zaugg for inviting me, and thanks everyone for making me feel welcome!

New developments at Ultimaker! Posted by Erik de Bruijn in RepRap, Ultimaker at 15:44
We've been really busy with many developments at Ultimaker! Most notably: the Ultimaker Controller, reducing lead times, adding individual 3D printer parts and lowering the overall shipping costs. Also, we're releasing an improved version of ReplicatorG. Test versions are available at software.ultimaker.com/beta.
Together with Julius, I made this cool video of the UltiController:

Just playing and 3D printing! Posted by Erik de Bruijn in RepRap, Ultimaker at 16:19
Usually, during the weekend I spend my time working on Ultimaker as a company, or I have social obligations. For this weekend, my wife surprised me in an original and heartwarming way. She said she had planned a little trip, but instead the surprise was that I could do anything I wanted, EXCEPT work. So I spent the entire weekend just playing with my Ultimakers instead of improving them or improving the company. A whole weekend of 3D printing!
I was pretty emotional because of her altruistic gift! Funny, I feel like I already have everything that I could wish for. The only thing I can't have enough of is time!
These are the results, so far:
I'm really fond of how the lion turned out! It was a 5 hour print at high detail setting (sub 0.1mm layer height).

[Presentation] 3D printing event, ... Posted by Erik de Bruijn in RepRap, Ultimaker at 12:47
Last week was the 3D printing event in Eindhoven, the Netherlands. Ultimaker exhibited there together with about 20 other Ultimakers, shown by their proud operators (see this Ultimaker blog post). There were also RepRaps, milling machines and LeBigRep was printing on site with their HUGE printer. A lot of bioplastic was consumed!
At the event, I was asked to give the first presentation. Below are the slides and recorded video.

Bernhard, an Ultimaker power-user at MetaLab Vienna, has gotten the Sprinter firmware working on an Ultimaker. Sprinter is written by Kliment and Caru, based on
Inspired by his impressive results, I've also experimented with this a bit more. The travel speeds you can get out of this are a little better. Without accelleration the max speeds are around 333 mm/s (FiveD firmware) and with accelleration they were up to 533mm/s (Sprinter firmware). Somehow the firmware doesn't seem to step the motors any faster. When you set the FiveD firmware at travel rates above 333 mm/s it actually goes slower than at 333mm/s. So somehow there's some microcontroller congestion or it's possibly a bug. The benefits of smooth acceleration are especially important for machines with a lot of moving mass. The Ultimaker isn't the most spectacular example for acceleration because it already can reach the high speeds without software acceleration. For the Ultimaker, the biggest benefits of Sprinter firmware are expected to result from an increased buffer size.
Anyway, to show you the speeds we're now talking about, this is the result:
With the help of Bernhard we finally made a few discoveries as to what causes a less smooth print at higher speeds (becoming noticeable at 70+ mm/s). When using ReplicatorG, the print results were not really much different, except when fillet is enabled in Skeinforge. Fillet is meant to smooth out sharp turns, but it turns out that it smooths out any kind of line segment also lines that nearly have the same orientation. Perhaps this behavior should be change with an angle limit. But Fillet causes the buffer to run dry because there are too many small pieces of G-Code that succeed each other in a very short amount of time. About every two visible segments, four lines of GCode are actually sent. This is, not coincidentally, also the firmware of the FiveD software.
All Sprinter prints were done from ReplicatorG, which now also has an Ultimaker Sprinter machine profile in the newly released ReplicatorG version at: http://software.ultimaker.com/. Note that: This Ultimaker release is not a fork of the normal ReplicatorG, it just undergoes some more testing and has the latest, tested Ultimaker drivers. All Ultimaker commits are publicly visible and offered for integration upstream.

3D printing from abundant sources: ... Posted by Erik de Bruijn in [NL] RepRap, RepRap, Ultimaker at 12:42
You should see this amazing solar powered 3D printer that sinters ordinary sand into glass. Both the source of energy and material are pretty much unlimited. I wonder if you could one day print entire sand castles, that you could actually live in! Of course we need to be able to 3D print those fresnel lenses out of sand... Plus we need to move the lens, not the castle (unless you're Mohammed). Perhaps that can be achieved in the way I proposed here.
Given that with Ultimaker I've got my hands pretty much full. I figured I'd blog something short that I stumbled across (via Forrest Higgs!) that I've been fascinated about for a long time.

Ultimaker shipping & open sourced! Posted by Erik de Bruijn in Ultimaker at 09:45
Good news, everyone! Finally, the Ultimaker is shipping.
It took much more work that we had ever imagined, and we knew it would be hard to design a complete machine from scratch and also make it easier to assemble, have a larger build volume, be robust and reliable. I really believe we've nailed it! One of the important strengths are the incredibly fast and accurate parallel kinematics and the optimized print-volume to footprint ratio (inspired by Ilan Moyer's design of the MIT MediaLab). Also, the extruder allows for mid-build refilling of plastic or color changes (inspired by Wade's extruder design). The Z-stage now also has leveling screws so you can more easily make use of that huge build surface. In total it really makes for an easy to operate and fast 3D printer.
The Ultimaker has just started shipping, and since we promised to publish all design files as open hardware, we've just published them to Thingiverse.com. Of course, business-wise it seems like a big leap of faith to do this, but we are confident that it will turn out very well! So happy hacking! We think the Ultimaker is really a good start, but it needs your ideas to be great!
