Ultimaker quality FAQ is like porn for 3D printers

Do you think it’s not really possible to get amazing resolution from extruder-based 3D printers? You’re wrong, and this post about the attainable quality of prints on the Ultimaker proves it. The Yoda bust seen above was printed with a layer thickness of 0.02mm. This is a hack in itself because this process actually used two different layer thicknesses. The interior of the print, which you can’t see, but serves as a support mechanism for the object was printed at 0.04mm, with just the visible perimeter printed in the smaller thickness. That trickery is just fine with us if this is the result.

[Dave Durrant] discusses the press the Ultimaker has received, which mostly focused on the relatively fast printing process this hardware uses. But he didn’t think the story of the quality you can get with the device was being told. So he put out a call on the mailing list to send in pictures of high-quality 3D prints and he wasn’t disappointed by the response. You’ll see images of busts, bodies, gears, animals, and art pieces. There’s information about how they were printed, but even those not interested in the particulars will appreciate the macro photography that gives you an up-close look at how far we’ve come with these table-top rapid prototyping machines.

Next generation Arduino manufacturing problems?

[The Moogle] just got his new Arduino Uno; wow, that was fast. What should have been a happy unboxing turned sour when he took a close look at the board. It seems that it exhibits several examples of sloppy fabrication. The the lower-left image shows unclean board routing, a discolored edge, and a sharp tooth sticking out from the corner. The shield header shown in the upper left is not flush with the board, resulting in a weaker physical union and a crooked connection. There are vias that look like they’re not be centered in the solder mask, and areas where raw copper is exposed.

It saddens us to see this because the original Arduino boards were so well manufactured. Keep in mind that this may be an isolated case, and as of yet the company hasn’t been given the chance to swap out the board for one that has passed a more rigorous quality control inspection. But if you’ve already ordered one of your own, take a close look and make sure you’re satisfied with it upon arrival.

Not sure what we mean by next generation Arduino? Take a look at the new hardware that was recently unveiled.

Update: Here’s a direct response from the Arduino blog.

Update #2: [Massimo Banzi], one of the founders of Arduino, took the time to comment on this post. It details the organization’s willingness to remedy situations like [The Moogle] encountered and also links to the recent Arduino blog post.

Complete the Hack A Day survey, win a shirt

Take our reader survey. Do it. Do it right now.  Do you think we should run more articles on the dietary needs of Llamas? Here is your chance to let us know.  We got a lot of great feedback from [Jason]‘s post, and now we’re ready for more. We’ve put together 10 quick questions that will help us get a feeling for what you want. We will be choosing 5 participants at random to give free t-shirts (the basic logo one).

Update: While we wait for our survey slave to get the changes made, please just put something in the fields that are mandatory(questions 7-9). Even if you put “no opinion”, we’ll get good info from the rest of the survey.
