Need I say more?
Well, yes. The pads definitely stopped the corners curling. One pad didn't print (dodgy patch on baseboard most likely) and that corner started lifting. Not having superglue to hand after Oz, I put a dab of hot-melt glue on that corner to anchor it down, and that stopped the curl nicely.
The mounting slots for the smaller motors are a little short, but I've fixed the STL file and uploaded it. I'll just hold this one on place with some cunning wire-bending.
Next, the carriage.

That looks great — I've been following the project ever since reading about it on the MAKE blog a few years ago, and I can't wait to get one and make my first copy!
ReplyDeleteWow! You're the man, Vik! PLA sure seems to be the ticket. :-D
ReplyDeleteHow many hours did that one take to print?
ReplyDeleteThat's about a 12-14 hr print. I can't remember exactly and the machine is kinda occupied printing the carriage now. These large objects use a truckload of memory to print out!
ReplyDeletePLA certainly seems to form well. It'll be interestign to see how it performs. It's much more rigid than CAPA but I know it will fracture with repeated stress. With our design, this may not be a big issue as not too many of our bits should flex.
Vik :v)
This is so impressive. This is the biggest printed object ever!
ReplyDeleteHats off to you vik...
Utterly brilliant Vik...
ReplyDeleteSuch cool work you have been doing on RepRap, Vik. This stuff is fantastic. I've been RepRap-lurking for some months now and it's amazing stuff. I'd read a bit about PLA but it's great to see actual pieces of it. Where do you get it? The only source I've seen (at least here in the US) is a place that sells plastic forks and knives and plates.
