Amedee.... To get back on topic... can you do the same test for XT? in the higher ranges.. then at the end a report on what layers had the best adheasion?>

SO... here I am printing.. and I get the most amazing results from printing Colorfabb PLA/PHA NOT XT at 250c. I accidentally had it set at the higher temp but it printed amazingly.. Fan cranked on full of course.. but wow?

the way this stuff prints.. I wonder if it might be better to just use large shells and no infill ... the infill is always garbage and brittle.. but my outer layer area always strong and ready to go.. they tend to bend before they break.. but my infilled parts crack like an egg..

Dear lord.. I have been back and forth with this stuff... a couple of things I have noticed... TEMP is #1 priority.. but I cant seem to dial it in.. If you have it too high.. which I tried because I had no sucess with lower temps 235.. too high 261+ and the print come out really brittle.. the colored stuff is usually brittle if it comes out matte .. if it comes out shinyish it is usually done right and can be quite strong.. but it is a battle getting the right ammount of cooling at the right times I have had terrible luck with most types of infill it just wont lay down properly.

I just noticed on the colorfabb site that they had changed the formula and rolls made before feb 2013 are 220-240 and newer are 240-260.... so I think that is where I got some of the confusion then. I am printing now at 255 and giving that a try ... but up till not everything I have printed has be pretty brittle.

I printed a bunch of new printer parts with the Colorfabb XT. I was under the impression that this material was much stronger than traditional PLA. However I am finding it to be very brittle... it does not flex at all without breaking.... and easily I might add. I thought it could be temp.. but that would mostlikey only cause breakage allong the layers. but it breads along the layer and againts them. so for not impressed. I am printing at 70 speed at 240c I have tried 250 and 220c as well. no change??? any ideas?
