This lesson is about creating a 3d mini house using 2D acrylic cut parts
1) Acrylic 3mm
2) Laser cutter
3) Online software – boxes,py
4) CorelDraw
The laser burns away a portion of material when it cuts through. This is known as the laser kerf
What is kerf?
“Kerf” is a machining term that refers to the material removed during cutting.

Why is laser kerf important?
The laser kerf is important because when you are fitting laser cut pieces together like box joints(the typical joint in a laser project) you want the edges of the joints to be tight fitted so that you do not need any glue.
How to test the kerf?
We will be drawing a square of size 20mm by 20mm and 30mm by 30mm as shown below in CorelDraw
Laser cut them and measure using the vernier caliper.
Measure the square
Measure the slot
The kerf is (20.1 – 19.8) /2 = 0.15
Boxes.py is an online box generator. We will in creating a tight fitted mini bird house.
I will be using Boxes.py to create a mini house.
The kerf value is place at the burn perimeter.
Download the svg and import into CorelDraw
