I just stumbled across this video on flexible materials, does anyone have experience with these good or bad?

Would love to see some pictures, videos, use-cases and print settings for these materials.

How does it compare to regular Flex PLA?

How is it different form Flex PLA? As in, what is it?

Have you watched the video? It’s definetely different from plain flex PLA. I’ll shoot Kai Parthy an email - see if he wants to shed some light on the matter.

Cheers, appreciated!

Hi Brian,

the POROLAY series ist totally different to homogene (100%) materials as flex PLA or other flexibles.

After printing your object in the same way you do it with other stiff filaments you rinse your object for 1-3 days in water.

But please read here some extracts, and open later the attached *.pdf to find all informations at the momentually available 4 different Filaments.

POROLAY is a serie of experimental filaments, printable with standard printers at about 220 - 240°C.

It´s a kind of meta-material with different properties at different stages:

  1. in it´s delivery form, it´s hard and easy to print
  2. after rinsing in water, remaining in water it´s very soft and gelly-like, print sponges with,
  3. dryed it´s visco-elastic, depending on quality of rinsing, it will be soft, leather like, or similar as cardbord or heavy paper, depending on which POROLAY you are using.

now please read the pdf.

If you found new applications for Porolay, please publish your results here :wink:

Please be clement with me, I cannot (less time) give further rapid support. It´s an experimental filament for science and makers.

all the best from cologne

Hello @kai_parthy

i bought the LAY-FOMM 40. Printing went fine but i tried twice the rincing and hade some problems. I rinced one print for a day and a second one for three days (pictures are from this one) with normal tap water. It was flexible and soaky as expected but as you can see in the pictures i think i didn’t get all the PVA out.

The other problem i had was that the prints started falling apart quite quickly (if i pinched it with my fingers for example), it was a big mess with all the sticky PVA… I just read the PDF and will retry with warm water and multiples cycles.

Printed with 220 / 40 °C on blue painter tape (Ultimaker 1).

There is at least one feedback i can give. If you throw it on the ceiling it will remain there :stuck_out_tongue:

Hello Obelix,

the layfomm 40 is the softest version (you wrote falling apart) , layfomm60 is more stiff,

both need some periods of fresh water for best rinsing results,

yes PVA sticks, it´s also used as glue,

best

Kai

OK, i will try with multiple rincing and drying write the results here. Do you know if using filtered water (BRITA or similar) makes it better/worse?

should not, some % alcohol (ethanol) did it once faster here, but tap water is enough
