Cooking toast on a 3D Printer

3D printers are amazing machines. They can take spools of plastic, and make virtually anything you want. But the real question is, can they cook toast?

Hi all. I had an old heated bed and matching glass that I temporarily used when my 3D printer was out of order. In theory, it could reach a temperature of 130C. Would this be enough to toast bread?

I attached some spade connectors onto the heated bed wires, which I had attached previously. Connecting the whole thing to a SLA battery, I could quickly feel it heating up. I used a piece of glass to keep it from heating up the counter top too much.

So, how did it work out?

After leaving it on the bed for around 20 minutes – 10 minutes on each side – I tried out the toast. It was warm on the outside, but the inside was still ice cold. So, unfortunately, I ended up with only slightly toasted bread.

If I wanted to improve upon my toaster, I would sandwich the toast between 2 heated beds, and I would put something heavy, like a brick, on the top. This would ensure good thermal contact, and would also keep the heat in. I think it could have worked out that way, and it would half the toasting time – the bread wouldn’t have to be flipped.
