Would love to know how you get your nozzles from not drooling during dual extrusions.
Also, is that delamination on your traffic cones?
As to that, it is a very basic but efficient technique : I use the "change tool scripts" to turn down the unused hot end while powering the new one.Quote:

Admittedly it is an efficient way to do things only in when the 2 colors are completely on different planes. It still works otherwise but it increases print time like hell.
So when I transition from white (hot end 0) :
M104 S0 T0
M109 S200 T1
And then the reverse
M104 S0 T1
M109 S200 T0
I usually add a little more text to move the head away from the build first and then bring it back (I think it uses G91/G92 and move commands).
Unfortunately correct, but this is entirely on my design. I wanted to overdo it and added a "radius chamfer" at the bottom that had a horizontal tangent... therefore it didn't work well since the first layer had nothing to support it. Print didn't fail though so I'll keep it once I fill the hole with compound.Quote:

Oh yeah... do you add all that code manually or does the software do it automatically?
S3D adds the code on its own if you put it in the tool change script.
For my machine it takes about 3 mins to bring the hot end to temp. So if it is only a couple times per print ... No sweat. If you do it at every layer... Better be patient.
Oh and i only do this with pla and pet... Never tried ABS so far.
A couple more things I made recently :
1/ a replacement for our waterski fin.

2/ a repair for a colleague : fits better than original !
Attachment 6742
Sorry for the newbie question... but waterski fin in PLA? Does that not degrade in saltwater? I thought that ABS was better for parts that would be exposed to the elements.
Actually, those two were made of PET from Taulmann. I don't know how PLA reacts in seawater, but I think the heat would have been the worst problem. The skis are sometimes left to dry in the sun ... PLA would be less than ideal.Quote:

Some more stuff that came out recently. The elephant was designed by LEFABSHOP. Very nice design, really well engineered for 3dprint, with articulated limbs and head.
The gear is a handout I'm preparing for an industry outreach to young students in poor neighbourhoods : D-impulse.

This one was designed by INTENTIONAL3D, and it's really well made : prints in one go without support. Very fun to see it being made.

Vice design by Spanner hands, I designed the kitchenette.

kitchenette - what does it do ?
gear wise - you'd be better off printing the moving encapsulated ones: http://www.thingiverse.com/thing:53451
set it to a 0.3mm gap in the .scad file and it pops off the printbed and spins amazingly well.
going to have to try that expanding platform thing :-)
It's just a little something for my 2 year old to play kitchen with... It's a play oven with a play hotplate and an exhaust hood.Quote:

Also printed that crazy digital sundial from MOJO 3D :

The kitchenette rocks. Amazing quality from the PMP! :D
A large scale project I've been working on. Quite proud of the result. Used slow set epoxy glue to smooth some surfaces. Works real great.

is it a boat ?
Yes it's a river barge.
