Large-scale 3d printer

Very nice. Let's see a HUGE print now!

hi nathan, will print something big one of these days and post the pictures.

How much plastic have you been able to push with your large printers? Anyone get past the 40mm3 / second, that is often quoted as the max for Volcano?

I ask, because I'm still on the fence between cartesian simplicity and corexy cleverness. I need about 185mm/s to get 40mm3 with a .6 nozzled Volcano. The machine is a basic cbot style cube of 60x80x80cm outer dimensions, to be built from 40x40 tslot and proper German linear rails.

What would you guys do?

but i'm dead serious about designing a driveable small car.

Just don't print it in PLA.. it might start sagging if you leave it out in the sun

I use 0.8 nozzle on a regular basis.
I started with 0.35 nozzles, but it's like trying to fill a large pool with water using a small bucket.
regarding your question, I believe the amount of plastic is calculated volumetrically.
regardless, choosing between a core xy and a Cartesian has little to do with this and more with the mechanics involved, with its pros and cons.
as I said, a core xy uses a loop belt. scaling up such a printer poses problems for the belt tensioning. if you want to go with core xy, you might want to consider some wide belts, as opposed to the typical 1/4" ones. I use 9 mm wide gt2 belt, but I believe there's some 15 mm wide belts out there (misumi, if memory serves).
a wider timing belt is less prone to guitar string effect, so that might be your way out of this.

and we have yoda.
build time: 45 min.
nozzle: 0.8
layer height: 0.3
printing speed: 2700 mm/min
slicer: smplify 3d
the print is less than acceptable, but tested the maximum safest speed.

already did something like that.
printed a visor clip for the garage remote, for my wife's car.
after a day of sitting there in the heat, the clip sagged.
will print in abs next time.

a cable clip that's going to go on the front side of the port extruder. also, my first successful dual extruder printing, given the known issues between s3d and smoothieboard.
used one extruder for pva support and the other for pla.
simplify 3d slicer
0.8 nozzle dia. both extruders
0.2 layer height

Smoothieware was just updated to fix the S3D problems, and apparently S3D did something to their software as well.

ha?
smoothie was updated, you say?
strange, i spoke the other day with arthur wolf about s3d and smoothie, he didn't mention anything.
could you please post a link to it?
many thanks, dd.
