Re: Klipper

I agree that reducing heat may cause the extruder not to be able to melt filament quickly enough to keep up. a ducgted fan does eem a good fix. keep us up on what you are doing.

best,
john

Re: Klipper

Thanks for posting on this. at the faster speeds, would you think that reducing extruder temperature a bit would be constructive?

Re: 3D Printed CoronaVirus Respirators

HI TomR, Did you seal the PetG part of the mask, and if so with what? Also,in full knowledge of the imposition of asking this, is it possible/easy to share the first part of your g-conde with us? Simplify3D gcode contains all of the settings in the first several page equivalents. Having this informa...

Re: 3D Printed CoronaVirus Respirators

Hi TomR,
this looks like a much better design than what I did. What did you slice it with, and print?
thanks for alerting us to this.

Re: 3D Printed CoronaVirus Respirators:update

i printed the straight from the box Montana Doc mask. Of course it didn't fit well. I think I can make a much better fit by varying the scale in three axes, not forgetting to also adjust the scale of the "grille." I fussed with the settings to print PETG but it still took 5 1/2 hours to print the ma...

Re: 3D Printed CoronaVirus Respirators

Jeff, I should add that my choice of PETG is not for its efficacy, to use a medical term of art, but because it's what's in the printer and I have (finally) a setup which produces consistent quality. PLA could be a better choice. If they lock down St Petersburg, I may not be able to get back to the ...

Re: 3D Printed CoronaVirus Respirators

It turns out that I can scale the mesh in all axes or symmetrically with Simplify3d. The website suggests this can be printed in 3 hours. best i can do is 6 using .2mm layers and PETG.

I don't think I'm going to make more than 2 of these things, so maybe that isn't a problem.

Re: 3D Printed CoronaVirus Respirators

I don't think I'll bother with the mask referenced above. I don't like idea that it has to be warm molded to the face, and then glued and sealed if you don't want it to leak. I'm going to make this one tomorrow: https://longliveyoursmile.com/3d-printable-mask-for-covid-19/ I like the looks of it, al...

3D Printed CoronaVirus Respirators

I've received offers from BangGood for N95 respirator masks at not-outrageous prices with 10 day delivery. I've had 100% good luck buying from them in the past, but mostly things where I understood exactly what I was going to get and had sufficiently controlled my expectations to cover minor disappo...
