This week assignment is to create a cool glasses and it must be a mixed design. I get inspiration from google and started design my glasses using Fusion 360 to create the frame and the side arms.
Reference
Software :
For create the 3d model
For slicing the 3D model
For turning the DXF file to RLD file
Machines :
For laser cutting
For 3d printing
Materials :
To fabricate the side arms by laser cutter
To fabricate the front frame by 3d printer
Dimensions :
I googled the eye glasses dimensions to make the design as realistic as possible. I needed to know the lens height and width and the bridge width to create the front frame sketch. And the arms length to create the side sketch.
Glasses dimensions
Design :
1- I started sketching the front frame of the glasses by drawing half and mirror it to get a symmetric sketch.
2- I tried to abstract my lines to basic shapes like rectangles or arcs so it will be defined easily. I make the sketch fully defined except some of the bridge lines as I draw them by Spline and fix it.
3- Make the screw circle 3mm.
4- Mirror the sketch to get the full frame.
5- Extrude the sketch with 3mm ( the Plywood thickness)
6- Sketch the arm by mirrored arcs and define them.
7- Extrude the sketch with 6 mm.
8- Edit with 3d feature to fillet the sharp edge behind the ears.
9- Give appearance to the part by choosing the body select appearance and choose PLA material and choose the color.
Laser cutting for the front frame :
I export the arms as a DXF file to prepare for laser cutting then open it in RDWorksV8 to set up the cutting setting and saving in RLD extension so I can start fabrication with the laser cutting machine.
Setting up the cutting parameters as week #1
For laser cutting after finalizing setting up the parameters of the file in RDWorks I downloaded the file into the laser cutting machine and operate the machine as follows:
Choose my file from the screen.
Adjust the focus.
Track the frame.
Make sure that the frame is inside the sheet of wood.
Run the file.
Slicing for printing the side arms :
- I dragged the STL arm file into Cura for setting up the printing parameters.
- Adjust the orientation by selecting the side face to align the build plate.
- Set up the printing parameters as fellow :
Layer height (0.3).
Infill (10%).
No support.
- Slicing for getting the Gcode . it takes 18 minutes and 4g PLA for each arm.
For 3d printing :
I transferred the Gcode file into the SD card and operate the machine as follow :
insert the SD card into the printer.
Choose the unloaded option to change the filament.
Using a flush trip pliers to cut the new color filament into a sharp end so the extruder can take it easily.
Choose loading the new filament.
After confirming the filament is clean I start printing.
Choose print from SD card.
Choose my file and started printing.
The bridge part which was drawn with spline in Fusion360 appear in intersection lines in RDWorks so my instructor suggested me to solve this problem by installing an extension that transfer the spline to Polyline .

Making these beautiful models. I was so happy for getting this result in a short time.
