Topic: Testing extrusion of polimers. Testing print

Attention! google translater
Recycling of polimers. It may be interesting to someone.

1. Testing extrusion.

PET
Temperature  melting  240-250 С
fluid, required drying, rapid Cooling below 70 С (for transparency)
HDPE
Temperature  melting 110-180 С
viscous, problem with filament diameter
LDPE
PP
Temperature  melting 170 C
good
PS
Temperature  melting 220-240 C
good
PC

2. Testing print
PP
good
PS
good

Re: Testing extrusion of polimers. Testing print

Are you still testing these things out? I'd be really interested in the results...

Re: Testing extrusion of polimers. Testing print

I'd like to see something about support filaments has PVA ever been extruded?

Successful tests with PP.

Cool.  Is the printed PP object still resistant to acetone?

Great man!!
Can you also create a print with abs or pla with the same settings and the same object, so that we can compare the objects?

Re: Testing extrusion of polimers. Testing print

PP is not soluble in acetone.

Cube is a former PP bottle of shower gel "Axe".
PS test soon. Once eat ice cream smile

I know, I just want to make sure the recycled polymer is not degraded in its properties. 

Great work!  I think I will try experimenting with PP pellets once I get my Filastruder up and running.

First what is PP?
What accounts for the difference between the ABS and the PP object?
Are they both the same .STL with only temperature differences or did you change other parameters? Are both printed at the same speed?

Thanks for the postings.

Re: Testing extrusion of polimers. Testing print

PP = polypropylene.

BTW, you can typically google a plastic abbreviation + "plastic" will typically return the type of plastic and more information about it.

Re: Testing extrusion of polimers. Testing print

parameters are the same. 
temperature changes only

What was the filament diameter variation?

Yes and people can also furnish definitions and links to any references, that is just common courtesy.

Re: Testing extrusion of polimers. Testing print

filament diameter variation 0.1 - 0.4 mm
depends on the temperature and speed extrusion

Re: Testing extrusion of polimers. Testing print

om2804, successful test with Polystyrene (PS) extruding or extruding and printing?

Both, there's a picture in the first post.

Re: Testing extrusion of polimers. Testing print

very interested to know more about polystryene in a SD3. you can buy huge bags of PS beads packaged as bean bag filler for very little cost compared to buying ABS pellets. hell, could probably even pick up an old beanbag at a garage sale for next to nothing and extrude miles of your own filament!

22

Re: Testing extrusion of polimers. Testing print

On the topic of new material. We may have colorant for most of these plastics you are trying out. When we get a chance, we will dig through the vast inventory we have. Would people be interested in colorant for PS and Nylons? Just to name a few

The amount of filament you get from the beanbag chairs will be somewhat less than expected as the pellets will shrink considerably when going through an extrusion process because of how they are manufactured.. but still if you can find one at a garage sale cheap enough might be worth a try smile they do have a pretty low melting point, would be curious to see how the foamed pellets go through a filastruder??? I wonder if you would have to speed up the drive or not?

true. there are expanded polystyrene pellets used in most furniture beanbags. i had a beanbag once that had more solid pellets inside, looked kinda like airsoft BBs, except lighter, air fluffed. unfortunately that particular beanbag went on the curb many many moons ago.

Re: Testing extrusion of polimers. Testing print

Hi,

PP was successful in what conditions?

My Filastruder is about to arrive and I am setting the environment.

Thanks!
