Ramping up the printer for this and next tri's student projects. Been messing around some more, tried a few things out with ABS and decided to experiment with PLA a bit. This means I've got LOTS of misprints from my experiments! Here's a few.
Students just finished their cars, which means printing about 300 wheels, at 80 a batch. Its SPOSED to look like this:
'sept when you experiment with hairspray instead of the ABS goop and the
prints don't stick, and you leave for 2 hrs to a class in a different
room. Then it looks like this.
Next up was a larger print with ABS and the hairspray stick 'em. Looks not half bad...
Until you look a little closer.
The bottom warped really bad because I forgot the fan was on... Joy's of
using ABS. Then I tried pulling it off while it was still warm and the
bottom stuck so hard to the glass (hairspray) that it "bubbled" when I pulled it
Pretty sure I have the hairspray figured out and it seems to work great. Finally, the kids believe me when I say it's for the printer and NOT my hair!!!
This one is just icky. Switched back to PLA and was experimenting with
temps, speeds, etc. Finally discovered a partially plugged hot end and
solved this little problem.
This is new for me: tried printing a hollow "shell". Came out okay,
and with a few tweaks I'll be doing this for all of the students cars
with a twist.
Here's what the inside looks like:
And some students cars printing. Notice the .05 infill density honeycomb pattern.
2 cars down, 73 more to go. Classes finish up tomorrow (we spend every class all day long giving the shop a deep clean) and the new tri starts Monday. Will be starting right of the bat with Tech 2 on the printer, so in a few more weeks I should have some more cool projects to post. I'm impressed with what these kids come up with, as you'll see when I get all of these cars done!
