Learn About 3D Printing And Doing Intricate Castings

3D printed original
Silicone mold

You can 3D print objects, primarily in plastic. However, you can also create 3D models which you can then use to make castings in other materials- jewelry in precious metals, figurines, miniatures, railroad and other collectibles, and even chocolate.

Henry Locke, Maker extraordinaire and creator of Flex Vat 3D printer components, built one of his 3D printers for us. SLA printing uses a vat of light sensitive resin cured by a video projector to create amazingly detailed forms- think Terminator with the alien rising out of the vat of goop!

The main focus of the presentation will be how to make silicone molds from 3d printed masters and using those molds to make castings:

  • Learn how the SLA printer works
  • Tips for designing and printing your 3D object to be casting-friendly
  • We’ll have one or more 3D prints to demo
  • We’ll make a silicone mold and make one or more polyurethane castings but also discuss how to work with other materials.

This event is free.

3D Geography

Pictures and maps really don’t give you a full idea of the scope of geographic and architectural features. Such 2D tools can’t show height or depth well.

Now you can 3D print any place on earth to get a greater sense of the terrain. Plus, many important buildings and other man-made structures are now available to be downloaded and 3D printed.

I’ve never been to the Grand Tetons, so I used a free STL mapper to print it out:

i could have done my neighborhood or even Antarctica if I wanted.

I found Fallingwater- one of Frank Lloyd Wright’s masterpieces- on a website and printed that out, too. The great thing about it is that it includes the terrain around the house.  You can see how FLW located the house on the lot and how it fits into its surroundings. I had known that a stream ran through the building, but only with the 3D model was I able to actually figure out how.

Come in and we’ll be happy to show you how you can use this software and locate models to use in your class or as conversation pieces.

Help Us Build An SLA Printer

Share



Henry Locke, Maker extraordinaire and creator of Flex Vat 3D printer components, will be at SouthWorks to help us build the SLA printer he demoed earlier this summer.

SLA printing uses a vat of light sensitive resin cured by a video projector to create amazingly detailed forms- think Terminator with the alien rising out of the vat of goop! It is great for intricate designs for jewelry and other items.

Henry has updated his design and we’ll be building it on September 9th. Drop by for part of the day or the whole day. No tools or expertise required.
