POROLAY-Serie overview:
07 / 2015
POROLAY is a series 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:
· in it´s delivery form, it´s hard and easy to print · after rinsing in water, remaining in water it´s very soft and gelly-like · dried it´s visco-elastic, depending on quality of rinsing, it will be soft, leather like, or similar as cardbord
· All filaments in delivery-form are stiff and unbreakable, printable with standard home-printers (repraps) · All objects are hot-sealable after drying · All properties: fibrous, felty, jelly-like, varies from environment (humidity), f.e. if an object is printed and rinsed in water, it is cuddlesome* , after drying it is a little more robust than in water · Micro-porous means micrometer-dimensions! You may not see the pores with eyes · All POROLAY-objects may filled not only with water, try to use emulsions of oil, glycerine, inks, salty solutions, or ionic liquids to make it conductive ! · Use it to transmit electronic signals by electric current, fill the pores with an electrolyte (f.e. salt water or ionique fluids) · Use it as membranes in electro-cells · The rinsable components of POROLAY are biocompatible (PVA is even often used as food-packing material, and the remaining porous part is also a harmless polymer) * An analogy: Put a soft piece of leather in water and feel it between fingers, it´s more soft and snuggle than in dry condition. Why? The water in the pores reduces the friction inside pores and between the felty fibres.

POROLAY-Series / Filament-Versions:
LAY-FOMM 40
Print at: 220°-230°C heated bed (Capton) may be cold to 50 °C
|
After rinsing: micro-porous & elastic for printing soft rubber objects with something about ShoreA40
the filament is made from a rubber-elastomeric polymer and a PVA-component that you rinse out with water, the rubber polymer remains as your micro-porous object |
· Rubber-like things · Dampers · Stretchable bands · "40" stands for very soft rubber · = Shore A 40 · See the pic with the printed " X ", after printing and after rinsing with water Print sponges with FOMM 40 |
LAYFOMM 60
Print at: 220°-230°C heated bed (Capton) may be cold to 50 °C
|
ShoreA60, (more stiff than Shore40)
|
as above, but Shore 60, (more stiff than Shore40) |
GELLAY vers.505 (stiff jelly like)
Print at: 230°-240°C heated bed (Capton) 80 °C
|
After rinsing: if wet: jelly-like if dry: stable, not elastic, but bendable
|
· f.e. floatables · marine animals · body parts
|
LAYFELT (LAY-TEKKKS)
Print at: 230°-240°C heated bed (Capton) 80 °C |
After rinsing: like orientated felt, stable, not elastic, but bendable, paper-like |
· to print stabil fibrous objects, f.e. water treatment membranes, in eletro-cells · bendable felty fabrics
|
Design rules: print less walls/shells and less filling%, to shorten rinsing time Please be clement with me, I don´t give further support or other help. It´s an experimental filament for science and other intelligent users. Use social networks to exchange your experiences.
|
Rinsing with water: · carefully rinsing with water (best warm) is the key for good results, · latest after 1 day you will clearly see the effect of changing in stability, · after 3 days all soluble PVA component may rinsed out (if you did proper) · stir and · change water from time to time · if available, use an ultrasonic cleaner · optimal cleaning effect with using a house-hold spin-dryer (removes remaining water) · multiple times: fresh water > wait > spin-dryer > fresh water > wait > spin-dryer · remaining PVA feels little sticky like sugar-sirup between fingers · remove all PVA, · if not, your object will not be soft as desired (PVA is a hard component)
|
Best printing results you get with dry filament ! Closed fresh bag is not a guarantee for dry filament ! Please dry filament before printing in oven at max. 80 - 100°C for 4-5 hours.
