Safety/Fashion Glasses

I made Multi use glasses out of resin and acrylic plastic. I used the resin for the frame and the clear acrylic for the lens.

I Used filament from the 3d printer to make all of the prototypes of my frame and I used the Resin printer for my final frame. For the lens I used a clear acrylic plastic sheet that is 1/8 inch thickness, I ordered the lens off Amazon and I we had the rest in the shop here.

This is the first step to Making the glasses. Getting the right outline in fusion. Nailing the original sketch in order to move on, It looks simple but there really is a lot to itl I started pout by sketching half of it and using a mirror line to mirror it to the other side make sure both sides were the same thing. Getting the right dimensions and constraints going is really important, making sure everything is joined together and at the right angles, so I had to use a lot of coicnident constraints. And when you see that's theres multiple lines that's because of the offset tool.

I did this about twenty five times to be honest. This is just one of my prototypes in fusion. This gives me an even better look after the sketch on how I want the glasses to look. But obviously its hard to see how big they are on a screen. Going back to the offset tool that I mentioned in the sketch this is where it comes into play, it makes it so I can get that slot in the middle of the frame, this slot allows me to pop my lens in and out without it just sliding around or falling out. The tolerance for the outline and lens is not much off a difference I wanted it to be as snug as possible because no one wants their lens wiggling around when their walking, it made it a lot harder to get in but once its in it fit good and there weren't any problems.

Like I said in the last step I've made countless prototypes for these things and this is one of them and the first one. I upload my fusion design to the 3d printer and test out the size and see how they fit and if their wrong then I go back onto fusion and try to fix what I think is wrong and try again. The print settings also play a big role the speed and temperatures of the printing, sometimes when I would have it to hot and to fast it would just go all over the place and be a huge mess, so I would recommend before you print to find out the right settings.

For the lens I would take my fusion model and trade the middle offset line and put that on the laser cutter. At first I wanted to make a cam and do it on the cnc router but that ended up just picking up the plastic because we had no way of keeping it down besides double sided tape and it just wasn't enough. So taking the design from fusion to the laser is pretty simple you put it onto incscape and for the settings its RGB and you turn the red all the way up, the red means cut so it will cut all the way through the part. you also have go change the thickness of the cut which you want it to be as thin as you can make it to get the most percise cut. Then you take it to job control where you get it set up and ready for the print.

For this step there was some problem solving that needed to happen. The base of the arms were way to thin they would start to snap off really easily. So if you look at the picture you can see that I made the base of the arms a lot thicker so it's a lot more durable and then chances of the arms snapping off is really low.
