CLASS – TECHNOLOGY, LASER CUTTING

SOFTWARE: Rhino 6, LaserWorkV6

MATERIAL: Plywood 100*100*4 mm

MACHINE: Laser Cutting Machine Raylogic AS-1290C

CHALLENGES: Create something press-fit


TASK / PREPARATION

The task sounded quite simple: create something pressfit using plywood. This task had a goal to develop our skills in Rhino and Laser cutting.

As far as we had only one material and small size of this material, I decided to make a two-sided keychain to make people on the streets happier. I had an idea to write something inspirng, which ended in “Hey, You! Smile ;)”.


DESIGN PROCESS

The sketch of the key chain came into my mind in the metro, so I decided not to waste my time and draw it in Rhino.


LASER CUTTING

After saving my file in .dxf format I passed to the computer, which is connected to the Machine. I open the file with “File – Import” and placed it on the “surface” of the Laser Cutter.

I had to make two layers:

  • general layer of cutting (Speed 9mm/s; Power 95.0);
  • layer for “printing” (Speed 200 mm/s; Power 30.0).

First layer cutted the key chain itself, second one was slightly burning the plywood to “print” the letters.

“Printing by Laser cutting machine”

Because of the problems with the machine, I had to cut it twice. Because of that, the size of connecting sticks was smaller than the holes. I had to use glue to connect it.


RESULTS & REFLECTION

As a result of the work, I created a key chain, which is actually is not a press-fit thing. The idea itself was not a press-fit from the start.

Laser cutting is a simple and cheap (materials) technology to create prototypes.

The task allowed me to understand the main principles of working with Rhino and the laser cutting technology itself.

As an overall result, I can now give people another reason to smile, when they see my key chain on the backpack.
