Laser - Columbia GSAPP

Laser Cutting

Overview

The makerspace provides lasercutting machines for enrolled students to help provide additional means of fabrication for their coursework. In order to use the machines, students are required to complete the laser safety portion of RASCAL training, and attend the makerspace orientation that reviews the space’s policies and booking procedure.

Laser cutters are available during operating hours of the makerspace.

Pricing

Slots are $5 per half-hour.

Laser Cutting Template

Template

Download the laser cutting template here.

This AutoCAD .dwg template can be used by students. It has the layers and line type calibrated properly for optimal cutting. The layers correspond to the cutting order and depth. Vectors to be scored should be kept on the red, green and yellow layers respectively. Vectors to be cut should be kept on the blue, magenta and cyan layers respectively. When cutting intense patterns or very close lines, make sure to distribute the cuts on different “cut line” color layers so that the laser jumps around and minimizes the chance of fire and damage to your job.

The template’s size is adjusted to the size of the laser bed (32" x 18") and should remain untouched. It is advised that you keep vectors inside the dotted line to ensure they are not cropped and/or missed by the laser. Please align your file to the top left-hand corner of the template whenever possible.

If you have multiple files to cut, simply copy the template on the same file. If there are different materials, simply label each copied template with the corresponding material type.

Do not forget to run the ‘overkill’ command in AutoCAD to guarantee that any duplicate lines are eliminated.

Laser Cutting Signup Schedule

Booking Procedure

Orientation and RASCAL training must be completed before booking. All slots must be paid before completion of booking. Cost of slots are $5 per half-hour. Bookings must be done in person during opening hours of the makerspace. Transaction must be completed in flexcard as we don’t accept any other type of payment.

Approved Materials

If you are unsure of whether a material can be cut, bring a sample of the material for testing and approval.

Acrylics

Remove the brown, protective paper on ONE SIDE ONLY but leave the other side adhered to the material. Students can only cuts casted acrylics (plexi glass) sold with brown paper covering as the other types with blue or clear protective film release toxic gases and cannot be cut. Plexis submitted without any covering will not be cut.

Sizing your Boards

On the 5th floor of Avery in the hallway connecting the studios, there are two cutting tables, near which is a laser cutting material size guide. This is basically a 32" x 18" wood frame that can be laid on your material to show you the correct size your material should be. It has metal edges and can be used as a straightedge for cutting.

Warped Materials

Matte board, corrugated cardboard, chipboard and museum board, make sure the material is not excessively warped. Warped material is a fire hazard and will prevent the laser from cutting the material all the way through.
