3D Printing in Five Minutes

Our first 3D printing class was last week. In case you missed it, here are some tweets from that night.

On Monday, we talked about microns and 3D print times. Our introduction to 3D printing workshop is quick and simple in comparison.

The Happy Bookmark is a simple design that starts with drawing a circle in SketchUp. The MakerBots use the metric system when printing, so we design using centimeters and millimeters. We start off with a circle radius between 2.3 and 2.7 centimeters. We then use the offset tool to create two perfectly centered circles within the original circle. From left to right, we draw a line just above the center to mark off the top of the mouth. We delete some spaces, erase some lines and add eyes. We add 1 millimeter of depth to our bookmark, which keeps it flexible, export the file as an STL and then load a few into MakerWare. A single bookmark prints in less than five minutes. We love how participants personalized such a simple design.

We have more 3D printing classes coming up, and we’ll be looking for a challenging design that’s also a quick print. What do you think of a pencil topper? We can sketch it all out in SketchUp, or we can show you how to import a drawing into SketchUp. We’d love to hear your ideas in the comments, or when you stop by the lab.
