3D Printing Forum

The piece I modelled and printed for the Ferrari 456 has been mentioned in autocar magazine, although typically they don't get their facts right.

Playing with a 3mtr high WASP delta printer, nozzle dia. 3mm with up cycled PLA pellets. Printsize is 100cm. diameter and 110cm high as max.
Did a renovation model for a few missing roof towers of an old monastery in France for a friend who is a ceramist and is going to live and work there.
The information I got was the size of the empty spot and photographs of the existing towers, and modeled from there, just guessing the shape/size from the photo.

Doing some fun tests as well, not very useful, other then decorative..

It looks a bit like those christmas tree prints. Half the UM office was printing those 2 months ago

Yeah I see everyone is printing the lion now with the whispy mane

I lolled today
I was browsing the UM site for job offers, to see what they currently have. Was curious to see what info they wanted when you'd press apply for job.
So I pressed the button, and got a popup saying thank you, we'll be in touch soon.
xD

So Nallath, if you see me around the office as a Senior R&D manager, the button does magic!

I checked that a while back, wondering if they wanted any help from this side of the pond.

I know they have some UM staff in New York City. And I met many of them and enjoyed them.

One told me to send a BB-8 part so I could see how well the new UM3 prints it.

So I did.

And never got a reply to that message. Or a follow up one.

(Shrug!)

@Titus A few of my colleagues were oggling me suspicously when I was laughing because of your post.

@LePaul Do you want me to bring you into contact with some people directly?

Glad I made someones day!

@Nallath, not really (in regards to the no answer bit) ..Matt in NYC was great to talk to and eager to talk up the powers of the Ultimaker 3. But he must have just forgotten me or, since i am not buying one or twelve of them, not important enough to follow through

But...if they are looking for USA help, let me know!

@PeggyB, is that extruder working well? Is the output consistent and well controlled?

We are thinking about trying to build a large printer with a pellet extruder at Stockholm Makerspace and have not figured out exactly how yet

@Meduza, yes, it is working well, though you have to take care that there are no big lumps of plastic between the pellets otherwise the extruder skips and you get immediate under extrusion. We did not try to recycle the failed prints (and there are a lot of them) only the pellets that we got. This beast has a heated bed of 100cm diameter, 70 degrees, otherwise the longer prints start shifting, although the print itself is pretty heavy. We spent a lot of time calibrating the thing because the settings they delivered it with did not work. Prints came out too big and when the nozzle was on the glass in the middle, it was 1cm above on the outer circle. But this we got sorted out and now the prints start ok.

Another thing is that retraction is not there, there is no wire to pull, it is a constant flow of plastic. When it is traveling the nozzle oozes and there is no way to stop a 3mm nozzle to do this. So you see a lot of spiralize shapes coming out of the printer or you have to do a lot of cleanup.

Is it a variable depth extrusion screw like the one in injection molding equipment or a regular auger type screw in the extruder?

Because tea needs cookies! FieldOfView sent us these. Whoo!

jumjumjum... they look gooooood....

@Meduza, I will make a photo of it tomorrow..
