|The process of Vaporfuse surfacing|
Parts are suspended in the processing chamber where they are exposed to a controlled amount of solvent vapor. The vapor condenses on the parts, interacting with the polymers at the surface and causing the surface to re-flow. After time, the machine heats back up, causing the solvent to re-vaporize and then it is extracted from the parts and the processing chamber. The parts are then thoroughly dried in the processing chamber, leaving behind just a newly smoothed surface.
The enhanced properties by vaporfuse surfacing
VaporFuse Surfacing is a green industrial technology that delivers sealed and smooth surfaces with improved airtightness, bacteria protection and part strength. During the process, the surface roughness is reduced to a minimum. The technology is suitable for finishing parts made with laser sintering (SLS), HP Multi Jet Fusion(MJF) and other technologies such as (FDM). It is compatible with a wide range of materials, from tough PA12 to TPU and other soft materials.
Sealed surfaces: roughness is reduced by up to over 80%, both inside and outside. It results in a better flow of water and air in each piece.
Productive spray painting: VaporFuse replaces the priming step and reduces time and material required down to a third.
Improved airtightness: Parts with a very thin layer thickness become airtight due to VaporFuse, allowing more design freedom and the use of less manufacturing material.
Reduced friction: Using VaporFuse Surfacing technology can create smooth parts with over 40% less friction, less abrasion and no chafing effect.
Improved stability: Printed parts with greater flexibility & reduced embrittlement.
Bacteria inhibition: VFS protects surfaces from bacterial growth, making them easier to clean and disinfect. That leads to washable surfaces, resistant to chemical and oily products, avoiding residues after cleaning the parts.
A green industrial solution
Until now, chemical smoothing was mostly linked to aggressive chemicals that can generate toxic waste, having a bad impact on the ecological footprint, but also might be potentially damaging for operators, as they were CMR solvents (carcinogens, mutagens, and reprotoxic). Therefore, the invention of a sustainable post-processing solution was necessary.
The solvent for vaporfuse surfacing is a non-CMR solvent, eco-friendly.
In addition, the system does not produce waste, due to a completely closed circuit with the integrated recovery of the solvent. The system can operate autonomously 24 hours a day, 7 days a week and is applicable for Industry 4.0.
