Hello everyone,

Today I received my package from Shapeways with a few 3d prints of my models (everything modelled in lw of course). It is really exciting to see the own virtual models in real life.

considering now to buy a makerbot or lysin printer to print at home. Real fun.

They look really good Svenart.
Do you have any tutorials on how you modeled and prepared your models to send off to be printed?
(Would love to know, especially the ring model)

The ring is especially nice, and I am in love with keltic knots etc.

The ring is awesome!

thank you all.

Modelling the ring was really simple. At first i created one of this celtic symbols (triquetta), subdivided and subpatched it, y-mirrored and cloned it 10 times in a row, and then i used bend to form it into a ring.

About preparing the models: shapeways has a very comfortable and advanced system to autocheck your models if they are printable or not.

Great info there svenart.
So your celtic part wasnīt welded right? it was just enough with the parts overlapping in order for it to print as joined pieces? I reckon that was the case?

So what do you expect to do by purchasing your own printer? the ability to skip shapeways(though I guess not since it deals with other techniques and materials)...or just the ability to check prototypes initially for testing?

yes that is true. Overlapping is enough, they donīt have to be welded.

To be honest, Iīm really not sure what I can expect. Shapeways is great but their prices are a bit too expensive. Printing for example a 12x12x8 cm castle model in plastic can cost there around 80-100 Euro. Printing this with my own printer would be way cheaper and I would have more control.

actually only certain materials can have overlap in Shapeways, many of them need to be welded or watertight or the fail in "loose shells" it also depends on who they use for the outsource as the reason Shapeways is expensive is because they don't have many of their own printers and they outsource the printing (so there is twice the delivery cost as they pick up the prints to evaluate them then post them on)
you should try 3d hubs, https://www.3dhubs.com/ it lists people with 3d printers that are local, I live out in the sticks a bit but there are still several printers just mins away from me, so you can remove the delivery charge and pick them up yourself, printers like the Formlabs can print at a higher res than Shapeways Ultra detail and you will find a lot of them on hubs, with much less markup.

thanks for the info.

I meanwhile always use overlapping geometry and had no problems so far. Wich materials do you mean wich could be a problem here?

I know 3dhubs and was considering to use it, but for some reason I decided not to try yet. It looks very promising, but it is not soo much cheaper depending on what you need and material. Have you ever tried 3d hubs?

Get your own printer and welded/manifold will be mandatory. Shapeways is in effect repairing/finishing the model before sending to print.

Print something with movable parts, like gears, with hole inside for axis, and connect them with small electric motor.. :)

They have some 3D printers for $400-$500

Your prints are indeed awesome!
If you consider buying Makerbot printer, I can give you a piece of advice how to improve it's overall performance and how to start using it quickly : http://3dinsider.com/speed-up-makerbot-printer/
Actually I can say that I really like Makerbot printers for their convenience.
