I presume you mean diameter to be within spec. I also presume that your spreading figure is 0.15mm and is independent of the model X and Y dimensions.

Rob,
Yes, the filament is rarely bang on size but the slicer assumes you gave it a precise diameter for volume calculation so I correct for variation in filament OD.
Bang on with "Spread" too ;-)

Nick,

It may be that the slicer I use is just too vanilla for the niceties of compensation for filament diameter. I use Makerbot slicer, an old version as the new one wants me to log on and asks me awkward questions about my Makerbot machine, which is a Wanhao 4DS. I think I may have a look at Cura, which I use for turning jpegs into lithophanes etc...

However, for what I do, accuracy is not so important.

Yeah measuring the filament is something that gets done on all incoming spools as they vary. SLA/DLP is getting down in price point but I am waiting for SLA1 as they have been doing a lot of work to make it work with as many resins as possible and i have clients in different fields who have interest.
