For makers who are complaining about extreme difficulty of raft or support material removal and rough bottom print finishing due to the removal, here is a tip:
For ABS material, print it at 220 - 230?.
If possible, adjust your 3D printer to print the cube within the recommended temperature and then when done, all the support materials can just easily peel off with only your hand...yes, without any tool, similar to how you peel off the orange's skin.
From my first companion cube before I share it here to my latest 10th cube, from the smallest 1? cube to 10? cube, I printed them all with the same print temperature setting. All of them, all their faces, top, bottom and sides are flawless, smooth, pretty and easy just like how GLaDOS intended it to be.
I printed my companion cubes with PP3DP UP! Mini 3D Printer with Octave Temperature Switch modification.
I just printed this in PLA on a Makerbot 2 and made it huge (4x4x4). I printed with a raft and support on the standard "high" settings in Makerware (Skeinforge slicer, 15% infill, 3 shells). The build took just a shade under 38 hours and used a LOT of filament. I don't know how much was left on the spool before I started but it was probably at least half, and I had to change spools at 96% through the build.
I have to say, it looks really good and printed really well. It has a nice heft to it - it's not heavy but feels sturdy. Removing the supports on the sides wasn't too hard, and they only need a little bit of manual cleanup and sanding. The bottom, however, is a nightmare. I can see through the raft and it looks really good, but taking off the supports and the raft is incredibly challenging and after an hour or so of work and a few accidents causing minor bleeding, I'm still only halfway through. It will take a lot of sanding after that even....but that's expected with any build of this size.
It prints a lot better in larger sizes than in small. I've previously printed it in 1x1x1 and .75x.75x.75, and you really don't get the impressive definition at those sizes. In particular, the four grooves surrounding the heart on each face don't come out well, whereas at 4x4x4 they're beautiful.
If there's any interest, I may post pictures once I've taken the time to clean it up and sand it. If you're a Portal fan with some good prints under your belt and a lot of time and filament, I'd definitely print this. Thanks for the model, Poh!
It's worth noting that you'll probably want to print this with supports.
I printed this on a Makerbot Replicator 2, on the following settings:
- "High", (2 inches x 2 inches) [original dims are: 1 inch x 1 inch), No Raft, No Support
Everything came out great (took ~5 hours), except for the bottom. Lots of stray wires/ribbony material rendering the bottom face a mess.
I'll have to reprint this with supports+raft, I'm sure it'll turn out much better. Thanks!
