I just finished my extrusion machine , and want to start extruding with ABS material , i want to know more details about the procedure of treatment of ABS before extruding , and the grades of ABS material that gives me the highest quality and the specifications of it ,and if any other chemical materials added to ABS while extruding or no ?
Since it seems no one wants to give you proper information regarding this thread. Let me start with this. Researching is your best bet before making purchases like this. There are multiple grades of ABS people tend to like. Personally I use MG94. Now when it comes to procedures before running it through the extruder, I'd recommend using a dehydrator to verify your pellets are fully dried. I usually run my dehydrator for around 6 to 8 hours before running anything through it. You can extrude with the provided pellets and pick up additional online, colorant is something you can get here https://store.os3dp.com.
When it comes to the quality of the filament you extrude, its dependent on your settings and everything else. I took the provided bag to make adjustments as I saw fit as it was cleaning the barrel. Calipers are your best friend when measuring the extruded ABS. Outside of that though, make sure to check the Spec sheet for any material prior to use and do account for the fact you will be having to make adjustments to get an even extrusion. If its too thin, decrease the temp by 1 or 2 C, if too thick, increase the temp. Giving the extruder the 20 minutes to pre-heat is also something you will need to do.
I'd also like to make a recommendation though regarding the extrusion process. When your extruding ABS, it does put off toxic fumes, make sure your doing it in a ventilated room. I'm going to be building a custom box for my own so I can filter the air and to remove the scent.
