Print2cast wax filament

Set up guide

OK folks far overdue review. So reset the min temp to 125 in the firmware actualy  wrote a new line of code  comments for wax commented out the old mintemp and commented for regular  use.
then set up to print first layer at 140 and other layers at 135. first layer a little thin but very flat ribbon so let 'er fly.
bed temp 70 c
just used the bed as is hair spray with no precleaning and no fresh coat.
printed with 60 mm per second 3 outer shells 3 bottoms an 4 tops. I was very impressed. not the best print in the world but not bad at all.
Some minor stringing /oozing issues but an easy clean up.

I have not tried to cast with it it is designed for investment casting. The oscars  that were awarded this year were reportedly 3d printed in wax . whether all 60 were printed or just the prototype I do not know. Aone marine  has done a video or two on thin posted on you tube. Hopefully in the next couple month I can do more prints and maybe a casting or two.
at $50 for a kilo not a terible expense many premium filiaments are close to this price.

I'm working with this material now but can't keep parts from curling off the bed. I'm running a FF Creator Pro with heated glass bed+hair spray @70, extruder @ 135, 20mm/s.  Brim outlines seem to help, but not with tall parts. Do any of you have any updates on what's worked for you?

When I was printing mostly PLA, I tried hairspray at one stage and it was lousy.  It turned out I was using the wrong type of hairspray.  It needs to have the right active ingredients.  Take a look here http://community.robo3d.com/index.php?t … ully.2365/.  When I found a hairspray with the right stuff in it, I was away.  I still prefer kapton or more recently Lokbuild for most of my ABS/PLA printing but the hairspray works well for me on wax.  It is still not perfect on large footprint prints and the wax is very poor for overhangs and bridging so I still favor slicing models up so I can print in multiple parts and stick them together afterwards to avoid overhangs and bridges where I can.  This is fine if all you are going to do is use the wax for investment casting.  It joins easily with a hot knife.  For my last wax printing, I ended up using a 2mm raft to de-stress the relative shrinkage between the bed and the part. This helped minimise the effect of the slight lifting I still saw.  Hope this helps.
