Printed our labs face shield design in PLA and HTPLA on a Cetus 3D MK2 to test the designs fabrication flexibilityBuild instructions include;Temperature 210C --Default for PLA in UPStudioLayer Height = 0.25 mmInfill 13% --Lowest infill setting in UPStudioPrint Mode MUST be FINEAlthought this increases time significantly (2.5-3.3 hours/part), thermal effects will appear on the visor at higher speedsIt is possible to print without raft, but it is not recommended if printing the entire assembly (headband, bows, and clip)Materials and manufacturers;PLA by HatchboxHTPLA, HighFiveBlue by ProtoPasta
