![]() ![]() When prints don’t stick to the surface, things start going wrong. Make Sure Your Print Is Sticking to the Bed Turning on the cooling fans will also spread the toxic fumes throughout the room, which obviously you don’t want.īefore printing ABS without an enclosure, make sure your printer’s cooling fans are disabled. Since you’re not enclosing your printer, it’s better to make its environment as neutral as possible. Adding fans will just make it even worse.ĪBS needs careful temperature control with slow cooling. Since you’re printing without an enclosure, it’ll be difficult to maintain that temperature inside the printer. Don’t Use Cooling FansĪBS needs very high temperatures to become moldable. In fact, if you’re printing parts that are only a couple of inches high, there’s no requirement for an enclosure at all, as long as the printer is in a relatively warm room without drafts. The taller the model is, the higher the chance of warping. However, larger objects will quickly cool down as they grow away from the surface. Small objects stay closer to the heated bed and thus retain more heat. If your 3D printer doesn’t have an enclosure, consider sticking to small models when you use ABS. ![]() Printing in a warm place without drafts of air will help, but a heated bed will make the biggest difference. Your print will cool down quickly without an enclosure or a heated bed, especially if it’s a large piece. However, ABS is a high-temperature thermoplastic. Other thermoplastics don’t have the same issue because their melting temperature isn’t as high. The first sign of warping is that the corners unstick from the bed and become slightly lifted. Warping can make one part of the object shrink more than another, which is particularly bad if you’re printing parts. Printing without a heated bed will increase the chances of warping, especially if you’re not using an enclosure. This means that it becomes mouldable after it reaches a certain temperature. ![]() It solidifies when it cools down, but it also contracts in the process. But if you’re already printing ABS without an enclosure, a heated bed becomes a must.ĪBS is a thermoplastic. With other filaments, like PLA, you can print without having a heated bed. They’re usually made of glass or PEI sheet and have some kind of material that helps plastic stick. ![]() Use a Heated Bedīeds are the surfaces where the first layer of printing is laid. Avoid being nearby while you’re 3D printing ABS and make sure you can ventilate the room before spending time in it again. But if you do that, consider staying outside while the printing happens.ĭrafts of air can increase the chances of breathing dangerous ABS fumes. We just said the room where you’re going to print shouldn’t have drafts, and closing windows and doors can help with that. If you’re going to spend time in the same room where your printer is, make sure the place has windows and is easy to ventilate. Print in a Ventilated AreaĪBS fumes are toxic, and that’s one of the main arguments against printing it without enclosure. Just make sure the closet doesn’t wiggle. You won’t be able to keep an eye on it, but it’ll certainly be protected from the wind. You might be able to fix this by simply closing windows and doors.Īnother solution is to put your printer inside a closet. The first thing you should check in the case of not having an enclosure is that your printer isn’t exposed to air drafts. Since the ABS will be exposed to the environment, air drafts could cause rapid temperature changes, creating warping. You won’t want to have any drafts going around during the printing. It also has its disadvantages, and this article will help you navigate through them even if you don’t have an enclosure for your 3D printer. Make sure your print is sticking to the bed.ĪBS has a lot of advantages: it’s strong, durable, and somewhat elastic.Here’s how you can print ABS without an enclosure: Luckily, a few tricks can get you around not having an enclosure. It needs to be at the right temperature and exudes toxic fumes. ABS can be a little tricky to print, especially if you’re doing it without an enclosure. ![]()
