Re: How long would it take you to 3D print this ABS plastic part?

Do you know or have an estimate of the temperature and pressure to mold ABS?

 "There are various considerations when melting and injecting ABS plastic
into a mold. For instance, the melt temperature varies between 170 and
320 °C based on the ABS and mold temperature. The injection molding
pressure also varies from 700 to 21800 psi."

 I find that temperature hard to believe.  Most references give a high
temp of 440F to 480F.  There are a lot of factors that can affect
required pressure including temperature, mold design, and the shape and
volume of the net part.

 Thanks. If I design something I have to plan for maximum values, which I can always turn down. The 4500# 20' log on the sawmill and hoist intended for 2000# and 12' is a constant reminder of the problems of increasing capacity.
 

In this case I was mostly just playing.  I have some real parts I'd like to inject with ABS, but I don't think I have enough machine for it.  I have considered I might set the whole machine in one of the presses, and push directly on the piston rod.  20 tons ought to do it doncha think.
