This week we worked with 2D designs and cutting those designs on the Laser Cutter and Vinyl Cutter. With the Laser Cutter, the assignment was to create a press fit kit. Since I have little experience in design with software, I opted for a simple design, that could allow the end-user (children) building blocks for their design. To start with, I had a bit of trouble with the design aspect in Inkscape. I started by drawing a circle and then adding a rectangle, but could not get the two objects to properly overlap and group. After speaking with my mentor, I switched to a basic rectangle design, and per her suggestion, I started with the notches instead of the larger shape. She also taught me about cloning and that allowed for easier manipulation of the notches later in the design process – each time the original cloned object is resized, all the clones automatically resize. The notch development was based around the use of 1/4″ cardboard and MDF (for the final cut).
Once I had the design set at a 2″ square, I rounded the corners for aesthetic purposes. Next I layed out a file with three of the squares. I did this in a separate document by grouping the original square, and cloning it. I cut the three squares on cardboard, and checked their fits. The notches were a bit too wide, so I resized the notches and did another test cut on cardboard. IMPORTANT – always watch the Laser Cutter when working with cardboard. It can catch fire easily!! With the third test cut, I was satisfied with the proper fit of the notches, and laid out a sheet with 36 squares, and then cut them out of MDF.
Using the final cut product, I built a tower.
My other project this week involved the Vinyl Cutter. I made some user guides for all of the equiment in the lab, and to make them look a bit nicer, I used the Cut Studio software to make vinyl stickers for the cover of each binder. It was a quick and easy project, but has a big impact. The photo below shows the process afer the cutting has occured. It is cut on the brown vinyl, I peeled away the excess vinyl. Next I placed a piece of masking tape on the words, and tranfered that to the binder. Finally, I peeled away the masking tape. I found one tip in the process – used masking tape does a quicker transfer.
On a separate note, I finally got a decent understanding of GIMP and resizing images 🙂
