I am about to assemble a Printrbot LC with heated bed and get started with 3D printing. I will be printing using PLA. Should I cover the print bed with glass or Kapton tape before I try printing for the first time or is that only necessary if I have trouble with the print sticking to the bed? Is there any chance of damaging the bed if I don’t cover it with something to begin with?
While, I have never printed directly to the a heated print bed, I certainly wouldn’t recommend it. I have always had a layer of glass on top of the heated print bed, and (until recently) had some sort of tape on top of that. When I was printing to tape, it was always wearing, chipping and eventually tearing. I personally wouldn’t want that sort of wear and tear happening to my heated build PCB. So I would at the very least put some tape (Kapton, or blue painters tape) down first. However, adding a layer of glass provides is even better, as it provides a great flat surface and also helps to evenly spread the heat from the build platform over the whole area.
Hi! Subconsciously you already know this, but let's make it obvious. Hopefully this article was helpful. You might also find yourself following a link to Amazon, Lego or eBay to learn more about parts or equipment. If you end up placing an order, I make a couple of dollarydoos. We aren't talking a rapper lifestyle of supercars and yachts, but it does help pay for the stuff you see here. So a massive shoutout to everyone that enables this place. Thanks!
