Vapor smoothing for SAF and HSS parts.

Vapor smoothing finishes Selective Absorption Fusion (SAF) and High Speed Sintering (HSS) parts the way it finishes other powder-bed parts: a controlled vapor reflows the porous surface into a smoother, sealed skin. On voxeljet HSS PA12, AMT measured ≤ 0.4%12024 dimensional change and +38.1% (XY)12024 elongation at break.

Questions

SAF and HSS vapor smoothing: questions.

Short answers from AMT’s published whitepapers and material lists. Anything else, ask an engineer.

Can SAF parts be vapor smoothed?

Yes. SAF PA12 is listed with PostPro Pure and FA326, and AMT has published process insights on vapor smoothing SAF parts with PostPro Pure.4

How much do HSS PA12 parts change dimensionally?

In AMT’s published test on voxeljet HSS PA12, dimensional change was ≤ 0.4%12024.

Which consumable is used for SAF and HSS parts?

PostPro Pure for both; FA326 is also listed for SAF PA12.3
