Laser projects


My idea or project must be created in CorelDraw, then I can transfer it to the laser for cutting.   This is a 2D graphic design program.  It is very powerfull and allows me options for my creations.  

Here is an example of a project I wanted to try .......  

I want to make a set of earings.  A tear drop about 1.5 inches tall.  The "SF Giants"  colors are Orange with Black.   

I'll draw the shape using CorelDraw  and put SF in the middle and see what it will look like cut out.   After many tries I finally figured out how to inlay the letters using different colors.  This turned out to be quite a project.  I used 1/8th colored acrylic.​

Below on the left is the drawing I created in CorelDraw X8.    On the right is what was  cut out.



We made and sold a few sets of these.  

Night light

This Challange was to create a night light using a cone, as a stand with an acrylic disk on top that lights up.  I found a cone at Hobby Lobby to use as a protype.  It was a type of cardboard and we painted it black.  I cut off the top and tried to get a beam to shine through the cut off top and centered.  Although it looks good it was not really round at the bottom and not very stable.  I tried different lasers and mountings.  Nothing was working out.  It was put on to a back burner for a while until a better solution turned up.

I am trying to learn the Autodesk "Fusion 360" a Cad program, so I can make 3d stuff to print, hopefully for the trains.  I drew a cone maybe for that night light  thing, and did the stuff needed to 3d print it.  This turned out to be quite a learning project.  My first attempt ended up to small.  Back at the drawing board.  With the new laser I was going to use, I needed a six inch base for it to fit inside the cone.  The top should be about 1 inch to support the 6 inch disk.  But a acrylic disk will need support too, so I need arms to hold it.  That means holes in the cone for the arms.  The next issue was recessing the base into the cone a little.  Once all this was done, I 3d printed this thing.  It took 13 hours!!!  It turned out PERFECT! 
Now I need to make the acrylic stuff.  The Laser was going to have a power cord, I need a slot for that.  The base should be off the table some, so now I need feet too.  In the image above you can see all the stuff I made.  The Cone (3d printed) with acrylic arms.  The  acrylic base with the laser on it.  The acrylic base with its new wooden feet.  Time to try it all out.
The two images above are using a 3 inch acrylic disk.  It works!! The support arms light up as well as the base.  The next two images are using a 6 inch disk, it even works better!!


One real surprise was how to get the laser aligned to the center of the display  acrylic disk.  I finally made a jig that helped with that, so I could then bolt the laser down.  I still need to mount the cone to the base and add a power switch.   All the acrylic stuff was made using my Laser Engraver.



 I exported the CorelDraw 2d drawings into Fusion 360 and converted them to 3d drawings.  The drawing below is my final assembly drawing using F360.  
Here is a video of me testing this lamp on the workbench in my Laser Studio.

The video below is another excersize of learning Fusion 360 and my laser engraver.  At the time of this creation Kadama was the rage everywhere.  I made a few wooden ones and then I wanted a acrylic one made with my laser engraver.  A great project.   

This animation is from my Fusion 360 drawings.
