3D Printing Safeties
Well, today I had a good idea and those are hard to come by.
On one of our globe mixers, it has a bolt on the backside what has a magnet in it so that when the bowl gets raised to mix, the machine has a way of confirming it’s in the right place.
That bolt got lost a while ago so I drilled a hole in a bolt and glued a magnet in it which then got lost yesterday, the magnet came out.
So today I had the idea of seeing if I could print a new bolt with a pocket in it for the magnet and then pause the print at the right time, set the magnet in it and let it continue so that it encases the magnet.
It worked, printed it out of nylon 12 which has a heat deflection temp of 120*C and is food safe and it’s semi transparent so you can see the magnet in there.
Pretty cool.
I tried taking some pictures of it but it’s hard to see since it’s a fairly small bolt.
Then it hit me that I Could probably do the same with some of the more expensive reed switches on various machines, probably end up better than ceramic casing with a reed switch epoxied into it which is what the OEM one is.
Buy the reed switch and then design it into the object and then print it, pause it, put the reed switch into the print and let it continue, sealing it up.
