Laser Cutting/AutoCAD
AutoCAD Laser Cutting Guide
1. Choose the correct laser cutter based on the material and its maximum cut size.
Your job should be smaller size then then Max Material Size.

TROTEC SPEEDY 400
DIGITAL MODELLING @ BUILDING 202
MAX MATERIAL = SIZE 900 x 600 x 12.7mm
Strawboard, Plywood, Acrylic, leather , other upon request
TROTEC SP500
DBE MAKERSPACE @ BUILDING 418
MAX MATERIAL SIZE = 1245 x 710 x 12.7mm
Strawboard, Plywood

2. Ensure that your objects are at the appropriate scale.
The Laser Cutter cuts at 1:1 scale.
For example, if you need your models at 1:100,
they should be scaled down by 0.01.
