Design and Printing 

Like all 3D prints, we start on the computer in a CAD (Computer Aided Design) software. In this, case Auto Desk Fusion 360. I have designed a pattern for a sand rammer. It’s a type of hammer that is used to compress the sand in a mold around the patterns.

The pattern is split in half to give us 2 flat faces. There is also a set of alignment holes for pins in them.

From the drawings, an STL file for each half is created. The STL files are then run through a slicing program to generate the Gcode that drives the 3Dprinter.

Both halves of the pattern were printed at the same time.
