Laser Cut

Laser cutting is a manufacturing process that uses a high-power laser to cut or engrave materials like wood, acrylic, metal, and more. It works by focusing a laser beam onto the material, which melts, burns, or vaporizes the material, creating the desired shape or design.

Group Assignment

We started experimenting to find the optimal laser power and speed settings for the specific material we are using. Determining the right laser parameters is an important first step, as the ideal settings can vary depending on the material properties and thickness. After identifying the suitable laser settings, Our next focus was on finding the most appropriate measurements for the joints or connection points in the design. This is a critical step for creating press-fit objects, where the parts need to fit together tightly without the need for additional fasteners.

Individual Assignment

lAZER CUT

Press-fit Assembly: The laser cut pieces can be assembled in multiple configurations without additional fasteners.

Parametric design - The design can be efficiently updated by changing just one parameter, enabling rapid design iterations.

I did the design using Cuttle.xyz. I satarted by adding 2 circles to the workspace, and then make them as Venn Diagram.

Usign the Boolean Difference tool, I made the Cresent.

Using the Mirror Repeat tool, I had a reflection of the cresent.

I added a line and used Rational Repeat tool to make 24 line as the guide.

I added new Component and called it HalfSlot and add a parameter

I added new parameter, and change it with these values.

I exported the design as dxf.

I imprted my design to the Lazer Cut machine software

Then I specified the speed to 80mm/s and power to 60, which are the values that we found perfect for the material we are using which is chipboard.

Finally, I downloaded the design in the laser cutter and uploaded it so the machine start cutting.

I opened the folder in the machine.

After the cutting done, I started Joining the parts

### Final Result #### Vinyl Cutter

I did this project using my vinyl cutter which is cricut maker 3.

I used the design space software to use cricut machines.

Download from here

This is how the homepage looks like.

I tapped on New Project.

This is the workspace.

I planned to design my libbey, So I measured it's size.

I chosed the images from the design space library and adjust the size.

I tapped make.

I chosed the load type which is on mat.

This is how the cut will be on each color.

I prepared the vinyl, and put it on the mat.

I connected the machine with my device.

I tapped the material base which it is Premium Outdoor Vinyl

I loaded the mat in the machine and once it completed scanning, I pressed Go.

Here after the cutting completed.

I started removing the unneeded parts using the weeding tool.

To place the vinyl on the libbey, I used a transfer tape. I placed it on the vinyl, used the scrabber to ensure that all parts of the design is sticked. Finally, pelling it of and ensure that all parts are sticked.

I put the libbey on the holder, and I placed the transfer tape on it. I used the scrubber to ensure that the design is sticked without any bubbles. Finally, I started peeling it off and ensure it doesn't contains any part of the vinyl.
