I wanted to build a cure oven that matched what Formlabs had to offer for a little bit cheaper. I cannibalized a Hamilton Beach food dehydrator (70°C max heat) and a 36W UV nail dryer. Threw in a 1 RPM motor, added 405nm LED lamps, a dash of UV filtering acrylic, one or two wires, a couple of switches, some plywood & stain …stir well and voila! Appx $180 and a few hours later it was done. I was going to add an Arduino with touch screen LCD for control and program presets for time & temp but I got lazy. Soooo the top switch is for main power and the bottom is for light and turntable. The original controls for the food dehydrator have been maintained which does have it’s own timer and heat settings.
The finished product…
1hr test run
Power test without the door attached
The guts getting all wired up…
Main unit fully assembled
Time to add the aluminum sheeting
I have been curing things in the sun before then I made a non heated cure box but now that I have done this I can immediately tell the difference. Before I could easily pop a print off the supports. Now it is so much harder. Just based on that I can tell that this was a success.
PS. One day when I’m in the mood I will redo the controls. Till then if I have to leave the house I use this to turn off the whole unit after an hour.
The dehydrator has a timer but the light and motor would keep going till I flipped the switch. I should have built this into the control but I literally found it a day after I put it all together. Maybe the next rainy day when I’m trapped indoors…
