Minecraft-3D-Printer

A program that controls a 3D printer built inside a Minecraft world. It provides an in-game GUI to design voxel objects layer-by-layer and then drive the physical printer apparatus to materialize them.

The program is written in FORTH and runs inside Minecraft using the Redpower mod's FORTH interpreter.

Requirements

• Minecraft with the Redpower mod
• A 3D printer apparatus built in-world and wired to the FORTH computer's I/O ports

Running

Load 3D_PRINTER.forth into the Redpower FORTH environment and execute:

3D_PRINTER.EXE

Object dimensions

The canvas is a 30 × 30 × 35 voxel grid (X × Y × Z, 35 layers).
