File --> 3D Print

Creating a 3D printing file from a Google SketchUp file has never been easy. Today a new class of 3D printing technology has slashed the time and expense it takes to create a physical model. Our friends at CADspan just released a plugin that allows for the generation of solid, 3D printable files directly from a Google SketchUp model. This software re-creates a model by "shrink-wrapping" it with one continuous mesh. The result is a single object, in STL file format, that is completely solid and ready-to-print.

3D printers create a physical object from a digital model by first dividing it into thin virtual “slices.” Then, the printers build the physical model, one layer at a time. These machines can typically build a shoe box sized object with almost any detail, overnight.



The new CADspan plugin makes 3D printing from Google SketchUp easier than ever. Install the plugin, and use the included tools to clean up and put some finishing touches on the model. When ready to export, click upload and let CADspan's servers take care of the rest. Then, go right on to working on your next Google SketchUp project while the first model is being resurfaced. When it's finished, simply download the STL file, review it, and the model is ready to print. Check out their User Guide for video tutorials and informative help. To see the rest of what the CADspan team can do with SketchUp visit LGM and Rapid Arch.

thats really cool. while its great to have plugins like this, i just wish google would keep developing the sketchup application. ever since google purchased sketchup, it seems as though development has completely stopped. maybe because google is involved in way too many markets and doesnt have the resources to dedicate. the mac version is still way behind the windows version and its been like this for years.

well, its nice - but at the end
this just shows how to clean the
geometry which is a ****** in the
current version of sketchup.

in generell your drawings should
be as clean as possible and water-
proof! so printing is just a matter
of export.

then again forming or 3d printing architecture is in my opinion no
option cause as long as you stay within xyz - pepakura or a generell
unwrap will do that job - ok you have to cut and glue it!

Is there a Mac version?

A Mac version would be coming soon.

In response to FMB's comment above:
While the video embedded in the post does highlight some techniques for cleaning up a model, the real power of CADspan is in the Resurfacer. See cadspan.com/videos for a look at "Why CADspan," which explains in greater detail the benefits of the resurfacer. In short, it removes extraneous interior geometry, fills small gaps that are hard for the user to find, and solidifies the Google SketchUp model, which is almost never solid. The end of this tutorial also explains why the Resurfacer is necessary.
In a few CAD programs, FMB is correct; a perfectly clean model will be able to be exported and printed. It is not impossible to export directly from Google SketchUp into a solid file, just very difficult. Even models that are "water tight" can have problems. CADspan makes ANY Google SketchUp model printable by resurfacing it. The point is that the user does not have to have a perfectly clean, every single object push/pulled therefore seems solid, model.
A combination of helping the user prepare the model for 3D printing (cleaning up) AND resurfacing the model with a single, solid STL file, gives all Google SketchUp users the ability to easily produce 3D printable files.

I tried to search for pricing in cadspan wedsite with little success. What's the general pricing?

The CADspan Plugin will remain free for non-commercial use. At the end of the beta testing period, November 8th, commercial licenses will be available for $39 USD/month. There will be yearly subscription discounts available, and special coupons for beta users, so download and register now to receive special offers once the beta is over.

im having problems with this plugin. i attempted to download the resurfaced 3d file after it was processed but was given the following message:

this file is invalid for use as the following: certificate trust list

This is not a problem with the plugin, this is Windows trying to open an STL file and not knowing what program to use. Make sure you select "Save To Disk", not open. Save the Zip file to your desktop, then extract it. You will then have an STL file, ready to view with SketchUp (use the plugin's importer) or any other STL viewer.

oh brilliant! thanks!!!

ive managed to view the stl in rhino but my model is now minus its texture rendering. just a bare shape. how can i rectify this pls?

I used an earlier version of Google SketchUp a year or two ago. I had heard this was a nice, easy to use program for doing 3D modeling, so I tried it. Maybe it's just because I'm not a tech saavy person, but I couldn't figure out how to make anything besides houses. I'm assuming that the program is a little more sophisticated now. Can you make 3D models of objects other than houses?

hi wa,

its easy to make easy models!
search for "basecamp 2008"
youtube or in this blog...
awsome collection of info

Please let us know what the status is of Sketchup 7. Does Google plan to release it? If not, I need to know so I can make plans.

The current version of the plugin does not save the texture mapping because of some complications with the .STL format, but I have heard there are plans to release a version with color mapping that exports .VRML or similar around the new year.

Regarding color and textures, the above poster is correct. We have a robust color workflow which will be in place for pro users this year. Please let us know if there are other features you would like!

Looks great. A lot of our clients (architects and designers) use SketchUp to design their concepts. With this tool we can offer our 3d printing service to print objects, models and maquettes.
