Improving 3D print quality is a bit of a black magic — there are tons of little tweaks you can do to your printer to help it, but in the end you’re just going to have to try everything. Adding a heated build enclosure however is one of those things almost guaranteed to improve the print quality of ABS parts!
And for good reason too — heated build enclosures are one of the outstanding “patented 3D printing technologies” — It’s why you don’t see any consumer printers with that feature. Anyway, [Bryan] just sent us his upgrade to his Makerbot Replicator 1, and it’s a pretty slick system. His goal was to add the heated enclosure to the printer as unobtrusively as possible — no need for people to think his printer is an even bigger fire hazard!
What we like about [Bryan's] build is that he makes use of a PID controller which allows him to set the build chamber temperature to anything he wants (+/- 1 degree). He’s also decided to use a high quality heater that is actually designed for heating enclosures, making it a much safer upgrade than just throwing in a little heater element with a fan to help spread it around. One thing to note about heated build chambers though — you have to make sure you don’t fry your electronics or steppers! [Bryan's] has used reflective insulation to help keep the heat in the chamber only, and has added heat sinks onto all of the steppers.
And if you’re more of a RepRap kind of printer, we’ve got you covered too!
