This is actually my first extrusion with a filastruder knockoff of my own design, so take this review with a grain of salt. First of all, the Ebay listing is wrong -- this is not an ABS resin, it's an ASA resin so it smells and handles very different from ABS filament that I'm used to. I extruded at 210 C, using the recommended 1/16" nozzle (1.58 mm). It came out pretty thick, between 1.86 and 1.9 mm. Going hotter with the temperature made the surface very bubbly and nasty, so I couldn't get it any thinner. Also, the filament itself came out extremely stiff, and hence refused to reliably coil. The resin also smells terrible. I have a different motor from the filastruder (10 rpm, 13 Nm), so I can't really comment on the speed of extrusion. However, it did seem to extrude quite quickly.

I haven't tried to print with it, but the smell is so strong that I'm rather hesitant to try. I think I'll have to pick up some MG94 as a point of reference.

Greetings all,

So i went through to the company who indicated that they have re-grind, but unfortunately it was not as clean as i had hoped so i guess that is not an option.

However they did have virgin styrene, which is essentially the S in ABS. Has anyone ever experimented with this? boiling pt is 145 °C.

What's wrong with it?

I extrude "trash" ABS through a melt filter, works fine. It has twigs and dirt in it.

Anyway - I'll leave it for the more well informed to comment; since I'm just going from my own summations and long forgotten high school science...

Hi,
Is it recommended to use regrind material? Its significantly cheaper here in South Africa, and i am struggling to find suppliers who have virgin material and who will sell small quantities.
If its suitable to use regrind, would it make sense to mix virgin and regrind to even out the batch?

Thanks in advance

I haven't tried it myself, but I've read that commercial plastic injection can use 10-20% regrind. More than that and supposedly the quality suffers, so they only use that for things don't need to be "consumer grade" - cafeteria trays, that sort of thing.

I would probable start with 80% virgin and 20% regrind and work from there.

Ralph

Thanks in advance

I was just trying to say, if you don't need the flame retardant properties, you can probably find a resin that flows just as well and costs less.

Shouldn't cause a problem with extrusion. It's flame retardant though, so probably a bit pricier than other ABS resins.

you can find the site by googling "muovinetti abs". use google translate to translate it to english

Really MFI is just an indicator of extrusion speed. Lower MFI is okay if you're patient.

Question is whether it is appropriate?
MFR at 220C, 10 kg is 42 cm3/10 min where MG94 is 42 g/10 min. As I understand by the density value 1 cubic cm is 1.05 grams.

I also found that LG Chem (Turkey) have several high flowrate ABSes like LG HF380G with MFR - 53.
