Face Shield Lite + easy mount+pins by FOR_MAKERSPACE

Last crawled date: 4 years, 2 months ago

This is a modification of our first model (https://www.thingiverse.com/thing:4238829). We made it and tested it together with FAB LAB Bucuresti.
Now it can be used both with non-perforated thin sheets (<0,3 mm), using the gap between frames, and with thick perforated sheets (>0,3mm) using the pins.
You can find the DXF sheets for the frontal, perforated and non-perforated. They are ready to be cut by laser or CNC.
PRINT PARAMETERS FOR a 0,4 mm Nozzle diameter:
It is just a reference based on the original Coronavirus Makers settings (Spain) and our own tests, as each printer (and slicer software) has its own parameters to ensure optimal prints.
-Layer height: 0.28mm
-Fill: 50%
-Fill type: Grid
-Upper layers: 3
-Lower layers: 3
-Shell: 4
-Flow (extrusion multiplier): 80% Important to ensure the thin gap keeping the plastic sheet!!! UPDATE some printers and some old materials need a bigger flow. Please make some tests. The exterior frame should move, but the whole thing has to be solid!
-No supports needed
-Printing speed: tested in 3 different models with good result

With a 0,80 flow, there are some chances of under-extrusion. It can lead to poor layer adhesion, especially in the frontal thin walls, ruining the functionality of the piece.
If it is your case, there are some fine tunings in the slicer software that can be made to fix the problem.
Parameters related to the extrusion width and to the behavior on thin walls will solve the issue. The idea is to avoid gaps in thin walls.
We would be pleased to help you get optimal results.
