#PSA / #PHA re. #Heat:

If you see people, espechally seniors, that seem fainting, disoriented, dizzy or frightened:

They may suffer a [light] #heatstroke, #hyperthermia or suffer from #dehydration.

If concious offer them a comfy seat in the shade and some cool [not ice-cold, but tap-cold] non-sparkling water.

A lot of seniors drink way too much and such simple remediations can help avoid the need to call an ambulance!

Thanks for sharing!

If I wasn't fully disabled, I'd apply. #PHA #NEO are stuff I'm interested in. Last time I calculated orbits was when I was still a teen, 4 decades ago. It's been nearly as long since I programmed in #FORTRAN.

@tagesschau wir brauchen vllt jetzt wo so viel PFAS in den Rhein geschüttet wurde Grenzwerte im Wasser - ja ; nicht dass es noch zu viele Mißbildungen gibt.
Aber an sich brauchen wir schon von Anfang an ein Verbot des Eintrages -> Solche Chemikalien dürften gar icht verwendet bzw. produziert werden.

Okay, remember Modulex, the literally #Lego but for project management 20th century product that vanished some years ago?

(Modulex: https://mastodon.murkworks.net/@moira/110060011477175062 )

Okay, now remember how I talk about #PHA #3dPrinting #filament occasionally, when I have time just to screw around with it, because it's so heat tolerant?

Well, good news. There's a set of new PHA colours out from the only North American supplier, and if you want to re-create some architectural Modulex, you have found your filament :D

#PLA / #PHA UM Blue 2.85mm 0.75kg - $22.75 https://tools.woot.com/offers/pla-pha-um-blue-2-85mm-75kg

A pretty blue color reel of 3/4 kilo of filament for your 3D printer. I don't know if it's a good price or not but there it is.

and off we go #pha #3dPrinting

I got asked on Reddit about #PHA "creep" behaviour, a term which refers to the material's ability or lack thereof to rebound from being weighted enough to distort it.

It's an interesting question, so I'm printing a somewhat-known test object to test with some weight. Let's find out, shall we?

Completed! No clogs. :D

Overhangs did WAY better than expected. 80° worked, though it looks awful from anywhere but the top. 60° is mostly okay, everything below that is perfect. Lots of room here.

The faint fine-detail surface text _is_ present and legible, but being a translucent filament it's not super visible.

Bridging isn't great but the very idea that I'd be trying that with #PHA is kind of a shock. I've seen worse, and this wasn't even at best temperature.

This is viable! #3dPrinting

so far so good and while this is the easy part the important bit is that it hasn’t jammed or fouled or any other such nonsense. #3dPrinting #PHA

oh ho ho success! (second from left) - gcode generated for 0.4mm nozzle, printed with 0.5mm nozzle. 180C looks best to me. ^_^

Now to print the standard printer mini test at 200.60. #PHA #3dprinting

Well, this is looking promising - trying my 0.4mm tower with a 0.5mm nozzle to see if that gets around the jams and preserves good 0.4 bridging but still gives a good print.

If this works, next up is the mini printer test object. #PHA #3dPrinting

And by "stark" I mean the _worst_ temperature layer I have so far is dramatically better than the _best_ layer I had with 20% wood-infused.

#PHA was already interesting to me, now it's much _more_ interesting.

@5thsq you should be hashtagging these for more eyes. #Philadelphia #housing #AffordableHousing #PHA

@smellsofbikes All it is really is a slightly-modified but very large toaster oven.

Here's a big #PLA / #PHA comparison writeup I did a couple of months ago:

https://solarbird.dreamwidth.org/1846697.html

#3dPrinting

tops look very nice - _very_ nice. 20% cubic and thick skins completely overcome the #pha bridging issues. Nice. #3dPrinting

@joncruz Which infill as in pattern? 20% cubic. I think it gives good strength and coverage. I'd've cut to 15% but I got worried about the top layers behaviour - see again #PHA not spanning well at all.

As for the supports, it's touching-buildplate-only, 63° overhead angle, 20% density zigzag. Otherwise just letting #Cura (v5.2.1) do its thing.

I've set three skin layers, which normally would be excessive for a 0.6mm nozzle but I'm hoping it'll help maintain a good top given the poor spanning.

Printing a little #totoro out of 20% wood-infused #PHA #3DPrinting filament partly to see how well it does with supports (since it spans very poorly) and also to see how it takes sanding and staining and all that.
