Adventures in 3D printing Sketchup models

3D Printing is for - Scale Models!
While making a custom hook is no reason to go out and buy a printer, this following example may hit closer to home for the architects on the forum.
A project I posted a few weeks ago, this scale model of a tiny cabin is useful for helping customers understand the layout of the home, and for marketing to potential customers.
3D Printed teeny tiny cabin in color

A little octahedron ceramic vase modeled with the Artisan plugin.
Hey cotty,
When you sent the model away for printing, did the STL preview look all faceted?
I ask because I was going to 3D print a ceramic stand, it looks smooth as hell in the sketchup model. But when I saw the preview from i.materialise, it looked all faceted, like it needs another couple iterations of subsmooth. I had to ditch the project until I get used to another program, shame because it was a contract with a big company in the UK.
With it being ceramic, are these facets actually noticeable?
I was under the impression the only way I could solve it is by using a solid modeller, like MOI 3D....but your model looks all nice and smooth, even though it has less polygons than mine below. I didn't order a sample because I need to print over a 1000 of these, I just need to get it right.
Here is the preview they sent me....see the facets?
(I know part of the structure is unsupported where the arrow points, I have actually resolved this now)
-
Here's the preview from shapeways, it looks faceted too.
In fact, I think the process will not allow faceted faces even if you want it that way because of the glazed surface. The face is much smoother than expected.

These are cool and all but what are the costs of a model? Can you tell me from above examples how much they cost in materials and time it took to make?

The delivery time depends on the material, in my experience: from a few days to 3 weeks.
Price preview for the vase model:
-
A holder of our plissés was repeatedly broken, now it is replaced...
(Alumide: ca. 2 Euro, Steel ca. 8 Euro)
-
Solo, they offer discount for bulk orders too.
Thanks cotty, that really confirmed my suspicions. Guess I was stressing out over nothing! haha
-
What I really want to know is the price if you have your own machine, I'm contemplating buying one, but do not know which one or what material yet.

Pete, a part made on a home printer will cost roughly 1-5% of a professionally printed part, but you also have a lot more work involved and will get a much lower quality product.
This cabin was printed on a pro printer (Full Color Sandstone from Shapeways) for ~$150:
The same cabin printed in ABS plastic on my home printer for $2.25, not including the 3 failed prints - and the model doesn't look nearly as good.
If I knew how to operate the printer better, I could get better prints. I've had it for 6 months now, and have had 1 major problem where I had to tear apart the extruder to clean out jammed filament, and several smaller problems that took a few hours of troubleshooting to correct. Home 3D printers are NOT plug and play yet, and it really depends on your needs and skill level if you want to buy a printer.
An analogy of using a print service vs your own printer would be sending a Sketchup model to a professional render guy and getting back a nice polished render made with Thea, vs. trying to figure out how to use Kerkythea on your own with no prior knowledge of rendering.

Carsten, I bet you just look for broken components in your home so you can print a replacement! haha great work!

It's that obvious?

3D Printing is for - Jewelry!
These are pieces that I designed in Sketchup, printed via Shapeways and i.materilise, and sell to medical professionals online. The parts are not 3D printed directly, but rather a wax model is 3D printed, then placed in a plaster mold, and finished using lost-wax casting and hand polishing of the parts. The best thing is that the print services take care of all the work, sending my customers or myself the perfect finished part.
The pendants sell from $69 for the smallest silver one to $450 for the big gold pendant.

WOW!!! do you sell the chains too? They really don't look like they've been printed at all....I know they've been cast from a print but they are sooooo smooth!
-
I was seriously impressed with that big 14K gold pendant. Shapeways just started offering gold a month ago, and that was the first thing I ordered. They sent it out in that nice case (for free!), which is a really nice bonus. I had it in hand in just 7 business days!
I don't sell the chains, but have been thinking to add them. It's one more thing to have on hand and keep track of, but it may well be worth it.

Pete, the best way to get a feel for these printers is to see one in person. There are local makerspaces in nearly all major cities that will let you come and take a look for free, or pay a monthly fee join to use the tools.
I looked up one in Dallas called the Dallas Makerspace: http://dallasmakerspace.org/
From their calendar, they have an Open House every Thursday night where you can pop in, get a tour, and ask questions. I have found the folks that frequent makerspaces are very receptive to questions and helping others get started in 3D printing and other useful skills. They can help you understand the different kinds of 3D printers and help you choose one that'll work for you.
For anyone else wanting to learn more about 3D printing, finding a makerspace (also called hackerspace) to see a printer in action and ask the regulars questions is an excellent way to get started. Here are a few ways to find groups with 3D printers:

Sending off a model to i.materialise today. Let's see how it works out! I was up literally all night, when I sleep I'll be dreaming in quads!
Quick question. For price comparison I'm also sending model to shapeways. It has to be in STL format and I'm using meshlab to export. So I'm exporting as Collada, importing into meshlab and exporting STL.
Problem is, my model is coming out tiny, significantly smaller than it should be. Any ideas what I'm doing wrong?
[edit] found a STL plugin which works fine, still can't think why the other method didn't though, even though I specified model units.
-
I'm guessing model units are getting mixed up in the process. Do you know about the STL exporter? If you use that, it's just one step and there shouldn't be any trouble! Protip - you can ZIP the file before uploading to speed the process.
-
That plugin didnt work for me on mac, version 8 sketchup. The created files contain no geometry and I've tried changing every option.
I used this one instead, worked first time. So easy!!
-
Nice find!
