Laser & vinyl cutters
this week, the assignement was to make a press-fit construction using
the lasercutter. I printed out a bunch of shapes and some connectors
and corners. Alot of the initial time went into optimizing the
slot size for the construction. I decided to go with cardboard because
there was alot of it and i could play around with it. The settings
which worked were 65% power, 15% speed and 100 PPI. I had to set the
speed manually to get the desired speed but I got clean cuts with this
with no fire :)
I tried first with some corners and connectors with 0.337" width but
with that size the pieces didn't fit nicely because the cardboard
wrinkled at the edges.
then made them 0.557" in width and printed all the pieces. I made ALOT
of pieces so i can play around. I printed parallelograms, triangles and
curved pieces and lots of connectors.
first thing i tried with the triangles was to make a tetrahedron, It
kind of works but I realised again that the connectors and corners
collapsed sometimes and wrinkled. I had put a little chamfer on the
drawings but I think that with the small dimension made the pieces very
easy to break. I still managed to get a stable tetrahedron.
then played around with the other shapes, I made a bad replica of the
Eiffel tower. The bad corners I had made it impossible for it to be
structurally stable in 3D so I made a 2D structure.
I have a ton of pieces left so I can make alot 2D structures. Feel free to come and grab some.
For the future, Be wary of the small pieces, they are hard to control.
Here are the dwg files I used :
