You’re the third person today to suggest I try some PLA. I’ll have to get some as all 4 rolls from the junk shop are ABS. I seem to be able to print little things but anything with a base bigger than 3cm or so is hit or miss.
This printed pretty well… A friend wants me to model him as a child in the outhouse. Of course, the model outhouse is in England, so he sent me measurements and I 3d printed a quick and dirty “throne” to fit the figure to. The raft stuck down so hard it was a little hard to get it off the build plate and the sloppily modeled seat (just two cubes) came out near perfect.
All this was inspired by my outhouse where a boy comes out holding his bibs up to see the train. The “animatronics” consist of a servo operated by an ATTiny 10 connected to an infrared receiver watching for a signal blinked by an infrared LED controlled by another ATTINY 10 running on a 3v coin cell.
Tom, I use Replicator 2’s and a 5 at my library. We only use PLA there, but our temp is much higher than you have listed. Our PLA is generally 215º - 230º C. Unless you know other design programs, I’d suggest you try . It’s graphic based and written for modern 4th graders, so us old guys have a fighting chance !
Since your bed is heated, you can probably use ABS with it. We don’t use ABS because ours don’t have heated beds, and ABS is supposed to give off toxic fumes.
BTW, PLA has no u/v inhibitors, so it should be painted to protect it if you use it outside.

So, what is it you suggest I try? I have OpenSCAD now.
I’ve gotten pretty handy at making 3cm tall tardises out of red ABS. A few weeks ago I printed a little box for my lab supply that came out good enough to work, but don’t look too close. I decided to try again and see if it comes out nicer.
After printing a perfect raft and bottom, it stopped extruding.
After printing a perfect raft, it went nuts and started throwing plastic threads randomly about.
After printing no raft, it put the bottom directly on the build plate and it warped so bad the head knocked it out of the way and started squirting plastic in mid air.
Now it’s about 1/3 done with one that looks nice.
I had been using “ReplicatorG” to slice it. “Makerware” just made a big mess. Then I opened both and set Makerware’s speed settings the same as ReplicatorG: 20 mm/second instead of 140 mm/second that it thinks is appropriate for the Replicator 1. Makerware seems to work nicely at that speed, but changes other settings unexpectedly. With all the settings “right,” Makerware seems to make nicer parts than ReplicatorG.
Nearly perfect!
