Ultra Fast and Light Consumer Face Shield

thingiverse

I Have 140 Printers, but I Can Only Run 4 or 5 at Once and Most Are Still Crated Up from My Move, So I Can Really Mass Produce Shields for #opshieldsup Etc. My Local Medical Facilities Also Aren't Short on PPE. (Rural New Mexico USA) But Our Local Shop Employees Are Largely Unprotected, and They Have Expressed an Interest in the Face Shields. So I Am Going to Make Them Some. I Have Materials for 100 (With Elastic and Clear Plastic Being My Limiting Factors), So Over the Next Week, Dollar Tree, Smith's, & McDonald's Employees Will Be Getting Some Face Shields. The Standards for These Are Not as Stringent as Hospitals - It's Just a Comfortable Barrier Protection That Is Light, Comfy, and Easy to Use. So Confirm First But Likely Hospitals Won't Want These. These Are Designed for Raw Performance and Frugality. 10mm Tall 1.2mm Nozzles 0.8mm Layer Height. Your Printer Will Go Slow, but Your Extruder Is Going to Scream. You Might Even Have to Slow Down If Your System Can't Melt Plastic Fast Enough (Volumetric Flow) or You Might Be Able to Go Faster If You Have More Heat Capacity. Gcode and S3D Factory File Included. 200x200 Bed 0.4mm Nozzle. It Is Programmed to Extrude a Line 1.2mm Wide 0.8mm Tall. Do Not Try and Go Fast - It Just Won't Work. This Is Programmed for 19mm/s and a 25-Minute Print (1.0 and 1.2mm Nozzles Can Do This in 14-17 Minutes If You Can Push Enough Heat). My Sequential Set of 4 in Vase Mode Takes 58-61 Minutes to Finish for 4 Shield Bands. To Slice, Set Your Nozzle to Your Nozzle Size. Set Your Extrusion or Line Width to 1.2mm. Set Your Layer Height to 0.8mm. 19mm/s. 80% Outline Underspeed. 240c on the Nozzle (230 First Layer as It's Slower - You Don't Want to Cook Off the PLA). I Doubt This Will Even Work with PETG Unless You Lower the Layer Height or Have a Volcano and Push 255c. Your Going to Be Extruding a Silly Amount of Plastic! A Gram a Minute Basically. No Top or Bottom Layers. No Infill. Just Vase or Spiralize Outer Contour Mode. I Am Seeing About a 10% Anomaly Ratio, So I May Drop Down to 0.7 or 0.6 Layer Height and Just Live with a 20-Minute Print Instead of 17. We Shall See. So Far the 0.4mm Is Working Great as Long as I Don't Push Too Fast (25-29 Minutes Print Time on 0.4mm Nozzle Which Is Still Silly Fast). About 23g of Plastic Each. If Using a 0.4mm Nozzle and You See "Tearing" in Your Extrusion, Slow It Down 10% and See How It Likes That. In the Picture the Green One Was Printed on My Anycubic Chiron with 1.2mm Nozzle the Red One Was Printed on My Creality CP-01 with 0.4mm Nozzle. This Is for a Standard US 3 Hole Punch. I Am Tired Tonight So I Will Upload a Euro 4 Hole Punch Version Tomorrow. I Still Have a Few Ideas for Shaving More Time Off the Print. The Trick Is to Remove Acceleration Deltas. ie No Hard Turns Etc.. Which Is Where Things Slow Down.
