robertspark Posted June 25, 2015 Share Posted June 25, 2015 What software is everyone running for slicing the stl? The supports, are you doing them in PVA or the parent material with a single head? Anyone running gcode and 2-heads how does it differentiate in the gcode (I'll probably answer that one later after a bit more reading) Thanks Rob Quote Link to comment Share on other sites More sharing options...
zoltan Posted June 25, 2015 Share Posted June 25, 2015 The Ultimaker 2 comes with Cura software for the G code, that takes an STL file and works OK. I'd like the dual extruder option now, got fed up of messy undercuts or trimming loads of support parent material away. There is a dual extruder kit available for the Ultimaker 2 from an Italian Ultimaker reseller for about 250 euros, I may try that since nothing is forthcoming from Ultimaker yet.

Cynic-al Posted June 25, 2015 Share Posted June 25, 2015 The objet has a very nice software package that you load stl files into. For the reprap I used one called something like skeinforge? Quote Link to comment Share on other sites More sharing options...
robertspark Posted June 26, 2015 Share Posted June 26, 2015 .... i was wondering how 3d printed things stand up to ultra-violet light (sunlight) degradation over time, given the OP's question was over the use of 3d printed things as signs, presumably that are to live external... rob Quote Link to comment Share on other sites More sharing options...
Cynic-al Posted June 26, 2015 Share Posted June 26, 2015 different materials respond differently but you may experience discolouration, brittleness and stress cracking. A good layer of paint would help. I would check how the chosen material responds to water, I think some were corn starch based? Quote Link to comment Share on other sites More sharing options...
robertspark Posted June 26, 2015 Share Posted June 26, 2015 PVA is starch based but used as a support structure it appears Quote Link to comment Share on other sites More sharing options...
