ok I have a "simples" solution and this allows an interesting possibility. Lets say you print object 1, you create the gcode and save the file, you then reload the same stl file again, you change the profile settings, but this time you move the object x distance on the platform, again you save the object as a different gcode. Now all you need to do is copy and paste the gcode from the second file into the first. It works! Once it finishes printing the first object it goes back to the start and then starts to print the next object. So its almost like creating one big batch file. :-P

Thanks guys! that's some great info. well cells love pla that's for sure although interestingly I never did a comparison with pla with dyes and pla without. With regards to the t glass material steve, that is very interesting but would it not be cheaper to simply buy in consumables rather than printing them? Plus considering what can go onto these well plates could be hazardous it doesn't seem sensible to recycle them... One last thing, does anyone know if there is medical grade pla on the market? that is for implants, surgical tools, etc? can it survive the rigours of autoclaving for example?

Hei! thanks for the replies guys. "well" what I have been doing is printing objects into 6 well plates and pitrie dishes. Sort of like osteoblasts (bone cells) etc It works fine if the object is of a certain size... so when it reaches the top of the object (the top of the well) then it moves across into the next well, then drops and prints the same object again. However if the object is really teeny then it hits the side of the well dragging the plate. There are a few solutions I can see, like 1. would be printing each object as a seperate gcode file (a real pain) or 2. editing each gcode file (again a pain) or 3. some sort of plugin that tells the printer to move up z amount (or rather move the platform down) after each object then proceed to the next one. We have been toying with the latter but having no luck so far. :-( While we could print a well plate, considering it needs to contain a liquid medium this isn't really practicle. Thanks, Jem

Ok so I want into objects, namely well plates. So I can make multiple objects, but when it makes one and moves to the next, it hits the well plate side. Is there any way to change the z height after the first object is printed and repeat for all of the other objects? Thanks! :-P

Hi thanks, I did see that but I wasn't sure if that was actually the correct one for ultimakers pla materials... plus it does not stipulate added dyes, etc I have used pla to grow cells on and it works fine in comparison to abs, of course however I do know that flexible pla is toxic to cells... Also does anyone know how much lead is contained in the brass extruders with um1's and 2's? Thanks!

H! Does anyone have a copy of this? The material safety data sheet? Is it food safe? Thanks!
