This week in the AT&T Classroom, morning campers have been working with 3D modeling tools. Makerbot Printshop and Leopoly 3D Content Factory both offer a gallery with templates that children can use for customizing and printing figurines, creatures, medallions, and jewelry. Makerbot Printshop also offers a Shape Maker tool that children can use to create a printable 3D model from their own drawing by capturing a photo of the drawing and importing the image into the tool. The 3D Slash interface offers a set of tools that children can use to build and modify 3D models by adding or subtracting a variety of cube shapes. Campers were also introduced to BlocksCAD, a web-based 3D CAD tool. The platform utilizes a block-based interface to engage children in 3D design while building skills for programming, spatial reasoning, geometry and advanced math.
