Re: Interesting article
The thing I found interesting was that they seem a bit challenged with cooling already printed layers. I've been printing R/C Airplane parts single thickness (0.35mm +/-) which are PLA and recommended extruder temp 230 and no cooling. The only way it can work without sagging is to print four or five sections at same time so last PLA layer can cool off before next one is layed down. I suppose they might be able to make it work if their temperature control is very good - no more heat than absolutely necessary and a well-focussed blower.
