What does a laser cutter do?
A laser cutter uses a high powered laser to cut intricate patterns into wood, acrylic, cardboard, felt, etc... Use the tutorials below to learn how to create files that can be read by the laser cutter using a vector imaging platform.
What is a vector image?
Have you ever printed out something from the internet and it turned out really pixelated? That's because most images on the internet are what are known as bitmap or raster images. Their resolution depends on what level of megapixel camera you have taken them with or saved them as using graphic design software. The bottom line is that vector images will never be pixelated because they are mathematical functions. They can be sized up to fit the side of a building and never change resolution!
Material our laser cutter can deal with that is usually in stock:
Sheet material acrylic
Clear, black, white (2, 3, 4.5 mm)
Transparent acrylic 3mm
Translucent(matte) acrylic 3mm
Colored acrylic (3mm)
Mirror acrylic (3mm)
Sheet material wood-based
Plywood (1.5, 2.6, 3.8, 4.8, 8, 10mm)
Balsa (5mm)
Paper card (80gr)
Cork (3mm)
Textiles
Stiff felt (3mm)
What does a file for the laser cutter look like?
Different colours are interpreted differently in by the laser cutter.
Traditionally bright red lines (HEX: #cc0000 / RGB: 255,0,0) that are thin (stroke width .001pt) are cut with high power and low speed.
Other colors are engraved at low power and high speed. The darker the color the more powerful the engraving. This way, even detailed photographs can be engraved.

Dear Ms Thao and (your teacher),
I have finished my tealight holder design and have attached it to this email. I have also addressed the areas below:
Created a 100% RED outline with a stroke set to .001pt for all the parts that I would like to cut through with the laser cutter.
Ahered to the size requirements for it to hold a tealight candle
Any areas of my design in 100% BLACK is so that the laser cutter knows to engrave here and not cut.
Thank you for your time, effort, and diligence in helping me to complete my product.
Your humble pupil...
