 Okay, so I have this here BFB3000. It's under plastic because there's an exhaust fan sucking the fumes away because I'm using some extra cheap plastic which smells a little bit more than the normal stuff. It's not too bad but still, I'm sucking it out. Anyway, one of the problems with the soccer fan is it sucks air through and keeps everything cool in there which is not preferable because already there's no heated print bed in there so when you're printing things they warp sort of like this one isn't too bad but it's still unusable. See it looks okay over here but over here see it it bent up and when it does that it starts mashing against the nozzle and making a bad job of the print. Anyway, this piece is totally garbage. Such a waste. Now I could just print everything out of PLA instead of ABS because the PLA doesn't warp. It might warp a little bit but not very much. Well, there's two reasons I go with the ABS instead of the PLA for what I'm doing right now. I'm printing out a big robot and there's all these precision parts that are going to be under lots of stress and they'll be moving around and creating heat and I don't want them to melt and the ABS has a much higher melting temperature than the PLA. The other reason and this is super annoying because I'm having a problem right now is that the ABS is much more ductile. You can bend it and the PLA here is very brittle and when it's going through the machine see when you print the parts out it's okay. They come out real strong and everything blah blah. This has to go through the machine right and when it's going through the machine it's often straightened and when it gets straightened if it's not warm enough it just snaps and right now inside my silly machine here this is the line for the second nozzle and you'll notice my PLA is attached obviously because in here it's broken about every two inches just full of little chunks and it's really really a pain to get that stuff out. I have to take the whole pipe out of there and anyway it's really annoying but the other day I decided I was just gonna make a heated print bed because I was I was feeling a little bit crazy and frustrated at the time and I was like I'm gonna fix this so I was looking around for a heat source to maybe do some tests I was thinking I could stick a candle in there just to do do a couple of quick tests but then I noticed I have a soldering iron laying around well I'm getting out of focus I must be getting too excited and worked up so this is my soldering iron right here and it's kind of attached to the bottom of the print bed obviously it's not just stuck there because it would it melt holes the heat had to be spread out so you know the soldering iron has a thing like this right this part gets really hot and that would be too hot so I got some some sheet metal I didn't really have much around but I did have one of these you know the rolls of plastic and it comes with a metal roll thing so I ripped that out flattened it out and put it on the soldering iron you know I just kind of wrapped it around so there was a big sheet attached to the soldering iron and the soldering iron has a screw so I put a hole in the sheet metal and screwed it right to the thing and then I put a few layers of aluminum foil otherwise known as aluminum foil whatever you want to say and because there's an airspace between the layers of metal it insulates the heat a little bit from coming straight out so it has time to spread spread sideways laterally and kind of spread the heat evenly around the whole thing so I wrapped I think five layers of foil on there it was enough that I the heat would spread out so I could put my hand on it without burning it it's pretty hot though and there's a little bit of space between the aluminum foil and the bed just because you know I taped it originally pretty tight but it's sagged a little bit but it doesn't matter it's working very well and if you stick my hand up here I can feel the bed is warm and the most important thing my pieces are coming out totally flat and not warped and they're really good so I can't say I would recommend you know sticking a soldering iron in your machine like that in fact I'm totally recommending not doing it so if you do that and melt a hole in your thing or burn your house down it's totally not my fault don't ever do that but it does work really really spectacularly well the machine is like it's it's like a new thing now anyway it's like a new machine now because yeah the bed in here is pretty big but before I could only print pretty small things with ABS which is the superior material to the PLA for anything that you want to be really durable but now you just print huge things so very excited about that and I'm gonna go back to just standing around watching my parts print takes hours yeah I'm not really standing around watching I have all this like toy robot stuff to do oh and just for details this is just stuck up here with a little bit of tape you know crap crappy cheap tape and here's the view from the side over here not the there we go oh and it's a 30 watt soldering iron probably could have gone with a 20 it gets pretty hot in there but whatever works
