Do you have pics of the before and after using your method?
no, i didn't find it useful enough to store / record as the effects of "ironing" are not very useful imo. it might have more use for some materials then others, dunno, the tests I seen online are made with PLA, I don't use much PLA..
anyhow it is easy to reproduce
1. add one more top layer to your process then you normally do
2. duplicate your process
3. divide object height by the layer height, set stop of first process at the height that's one layer shy of the top of the object (e.g. if you have 25mm high object and print with 0.2mm layer set the end of process one to 24.8mm)
4. set second process to start where first process ends and change second process extrusion multiplier to smallest value allowed by the s3d (0.02) and increase temp of your extruder a bit, you can also change the speed for better effect... so all in all in this process you define how you want that ironing to be performed
5. slice and try
sample picture, last layer is printing with 0.02 extrusion multiplier and slow 4mm/sec, as you can see below it (layer 99) it's 70mm/sec normal 1.00 multiplier (20mm cube, 0.2mm layer 19.8 stop of first and start of second process)
now, this does the "ironing" .. useful or not is up to everyone to decide themselves... also the part will be printed lower by 1 layer, so this 20mm cube will be 19.8mm and not 20mm.
integrates with Simplify3D and allow you to
Calculate print time accurately (acceleration, max speed, junction deviation all taken into consideration)
