Live Stream Q&A

Recommended Posts

Hi All,

I hope you are all enjoying the Live Stream from Erik's speech.

While you are looking, I am monitoring this topic.

If you have any questions you want to ask Erik regarding the Ultimaker 2 you can post them here and I will ask them to Erik on your behalf!

Looking forward to hear what is on your mind!

Hi Sander,

I am really enjoying Erik's talk and I indeed have two question:

Will the UM2 support the use of the Doodle3D that is being developed?

Will you come up with a scanning solution or will you stay out of that?

Thanks in advance!

Kind regards, Guy

PS I know you all are busy but please also look at my e-mail to info@ultimaker.com.

I have a question. Why are the sides of the new machine closed? If you wanted to create a heat chamber you'd need to take the motors out and enclose all four sides (left/right, front and top). Are you preparing to add an enclosure on top and on the front panel?

Hi All!

Thank you all for watching, staying up late, for caring and for supporting us in so many ways.

I'd like to know a bit more about the reliability of the extruder. The extruder on the Ultimaker 1 gave me problems every once in a while. Has this reliability been approved?

I mentioned it briefly. We actually had two competing designs for a long time and we ended up going for the current one because it was the most reliable and really easy to take apart for even a beginner. Also, it uses active cooling, so that prevents backflowing problems a little more.

Will the UM2 support the use of the Doodle3D that is being developed?

We've been testing with Doodle3D just recently and we can confirm that it works nicely with the Ultimaker. Actually we've already had the 'print' button on YouMagine working with the Doodle3D box as well, but it wasn't ready for prime-time and the things I had developed for it needed further development to become good enough for a release (e.g. security wasn't properly handled, you couldn't really delete from your queue, etc.).

PS I know you all are busy but please also look at my e-mail to info@ultimaker.com.

We well have to try to answer most e-mail after the weekend, because firstly we're demo'ing at Maker Faire and secondly, well it's weekend.

The hot bed wouldn't work if the sides are open, too much air draft, and therefore too much heat loss.

Wow nice. Uploading source files and .stl files directly from Cura to YouMagine...

Sharing is important in our eyes. And one of our main issues with thingiverse is easy to explain, the lack of source files. I scraped the first 40.000 things of thingiverse, I downloaded all the file names.

There are on thingiverse, in the first 40.000 items, 51381 STL files. Which are raw files, mostly only good for printing and minor modification. 6917 SCAD files, which are great for a select few of us. But then the numbers get even worse, only 1123 sldprt files (which are solidworks parts) 476 step files, 568 blender files, 128 123D-design files, 3448 sketchup files. So in total, there are about as many SCAD designs are other designs, and design files are dwarfed by the amount of raw STL files. (And the customizer most likely made this numbers worse)

With the YouMagine upload from Cura we hope to combat this. As it assists in uploading your design files with your STL files in a few simple clicks.

Now, the extensions that I know for designs are:

['.scad', '.blend', '.max', '.stp', '.step', '.igs', '.iges', '.sldasm', '.sldprt', '.skp', '.ipt', '.dwg', '.123d', '.wings']

But if people know more, I would love to know them.

Same for photos, we think photos are important, so the upload function also allows you to quickly take photos with your webcam, as well as select photos from your disk. Another idea is a phone app to quickly take and upload photos to YouMagine. (So many ideas, so little time)

.prt is the Siemens NX (previously Unigraphics) extension. .

A bit specialist I know, but there are a few of us out there, mainly surfacing and tooling guys.

also .x_t is the parasolid extension used by a whole bunch of packages based on the parsolid engine.

When you capture the source data, I think it important to capture the release number of the software that created it, as most often packages cannot read versions ahead, and sometimes versions too far behind what you are using.

.FCStd is what FreeCAD uses

Thanks Erik, I appreciate that!

I also just came back from a nice weekend so no worries and I'm very confident about the future!

Thanks for all the extensions. I've added the missing extensions.

There are no end-caps at all. The front is only milled "half deep" and there are plastic spacers between the pulleys and the casing that keep the rods in place. This also keeps the bearings in and no longer causes the rods to grind against the end-caps.
