Greetings everyone! One of the most difficult things to do these days seems to be sitting still! What have I been doing to keep busy? I setup a 3D Printing farm to produce ventilation masks to help with the shortage. If you're interested in following the engineering log, here's a link to the wiki.

Project Phoenix - Filtration Masks

Right now we have around 60 masks printed in two sizes. Regular and Medium. We've sanded and washed those 60. Now we're installing the face seal, nose pad, and elastic. For this, we're using 1/4" weatherstripping. Unfortunately, we only have enough weatherstripping to finish 12 masks for the hospital for today's donation.

April Fool's Update! The printers have been going nonstop. We have about 30 more masks ready for sanding. We bought 200 yards of elastic, and are waiting on a shipment of 100 yards of weatherstripping to create the seal around the edge of the mask.

Last night, FlashForge2 had a "catastrophic failure". At 2am, I removed a big ball of filament that had amassed on the extruder. There was a lot of filament dust on the print bed, so it appears there was a bit of friction. Need to assess it for damage.

Today's goal (after completing a few college assignments):
  • Assemble and Code the DaVinci Spool Resetter
  • Create a DC converter for the 3rd FlashForge
  • Create a spreadsheet to plan out cost projection


Here are some pictures.

This is an overhead shot of everything from last night.

These are some of the more interesting prints. When one spool runs out, I can fuse the next spool, creating a two toned mask. So we have some Firebird, Dolphin, Raven, Orioles, Superman, Spiderman, Bumblebee masks.

This is a closeup of the inside of a mask. See how fuzzy and stringy it is? This is why all the masks need to be sanded. Those fuzzy things can be sharp!

200 yds of elastic! $80!! Like zoinks Scoob!! O.O

This print is going to hold the circuit board (arduino) that will (hopefully) allow me to reset the dreaded DaVinci Mini locked filament spool! If this works, we'll be able to the two DaVinci Mini's back to the printing farm.

We're bagging up 36 new masks to donate to Riverside Hospital.

These are the masks that came off the printers yesterday. These need to be sanded and sealed.

To cut the elastic, we used a woodburner with an edge attachment. It cuts and cauterizes (prevents it from fraying) the elastic at the same time.

More masks that need to be prepped.

I had no clue you could even print masks in a 3d printer thats so cool!
