First Shapeways order

I did a 3D model for a friend and it needed to be printed in metal, so I sent it off to Shapeways.

The results are, it's not bad but definitely not up to being used as a replacement for machining, but I think we will be able to use the piece, after some rework.

There's a small vent hole in the top which was closed when I received it, but it appears it just wasn't broached well, a small drill cleared the printing powder easily.

The OD of the original was 14.18mm.  The printed object is around 13.9mm.  The ID was set at 6.09mm, the printed object varies from 5.95 to 6.09mm.  So in general not bad at all.

The surface is fairly rough as you can see in the photo. It'll probably do for this application, though.

The material is quite hard. Drilling it out round is pretty difficult.

What was the name of the metal, and do you know what process?

Thanks for all the effort put into blogging!

It's stainless steel, Shapeways has a page where they describe the process.

"To build steel models, special 3D printers deposit small drops of glue onto layers of stainless steel powder, one layer at a time, until the print is complete. We carefully remove these models from the printer. At this stage of the process, the objects are very fragile, similar to wet sand. The models then go through an infusion process that replaces the glue with bronze, creating a full metal product. Models are then processed to achieve your desired finish, sprayed with a sealant, and shipped to you."

New printer: JGAurora A3

This week I decided I'd had it with all the other printers in my stable.  The CTC is stable and decent but it just bugs me (can't st...
