thingiverse

PPERD Face Shield ================= The standard design features an adjustable droplet guard and extra-long arms (DG ELA) -------------------------------------------------------------------------------- Versions with Short Arms (SA) and UltraLight (UL) are also available, minus the adjustable droplet guard. ---------------------------------------------------------------------------------------- 90/day output (UL SA) ------------------------------------------------ - The adjustable droplet guard provides additional protection as required by international safety standards. - Optimized for Fast printing, particularly with large nozzles (0.6-0.8mm) - Stacks perfectly well for overnight printing (stacked STLs included) - Clear material requires no perforations - and an A4 or A3 sheet is clamped by front rim feature in landscape or portrait. - It's beneficial to use some foam on the forehead area, see image for recommended material. This should be considered disposable, so provide extra. For larger heads, remove the small bridge between the headband and roof section to allow more flexibility. -------------------------------------------------------------------------------- Currently my Prusa 3 can output 40/day with a 0.6mm nozzle, 90/day of the UL SA ------------------------------------------------ If you rotate 10 degrees on a Prusa print bed, you can nest two stacks of Long Arm versions. I can provide other stack configurations upon request, but most people should be able to handle this on their own. Stack each on top of each other with a 6mm offset. There are small inbuilt supports to help bind layers while still easy to break apart. ------------------------------------------------ Solidworks model available upon request ---------------------------------------- Print settings ----------------- 0.6mm nozzle works well for speed 3-5 layers 2 top/bottom layers 2-4 walls (depends on nozzle) 0% infill Turn off any thin wall/fill gaps options I print in PLA at 220C, 95% flow Speed can be as high as 70-80, just go very slow (15mm/s) on the first layer. Acceleration and jerk settings help, but are printer specific I have been printing in PLA which is VERY reliable. PETG has advantages, but is less reliable on the print - it tends to string occasionally. Recent version history; --------------------------- v8 - - Supports added to reduce stringing and a lack of bonding between stacked models. - Height of body reduced to 5.7, with 0.3mm supports. This simplifies stacking to 6mm offsets. - Standardized widths of members across model - Lengthened joining strut a little - Opened slot up to allow easier insertion of 200 and 250 micron lens stock
