This face shield has undergone review in a clinical setting and is recommended when fabricated as instructed.

This is a Rapid Application Group design optimized for selective laser sintering (SLS). This will allow those with Selective Laser Sintering or MJP assets to have a clinical tested design for production. This was designed with a local consortium that Rapid Application Group lead with local healthcare professionals.

• Single side sticky foam can be sourced for comfort against the forehead
• Flexible side straps allow for any size
• Standard threehole punch design for transparency attachment points

Bill of Materials (BOM):

• Selective laser sintered modified RAG Chase Shield V3.0.stl
• Duraform PA12, EOS PA2200 – 33.3 % virgin material 33%
• Multiple attaching material to secure the visor– standard rubber band, 550 cord, buttonhole elastic, standard elastic
