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

If I am honest with myself after the injection press is up to temperature, and the mold is preheated it's probably about 2-3 minutes per part net to hand inject these.

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

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

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.

According to John Taylor 20 tons is the chamber pressure of a .577 elephant rifle which can solve any problem it's applied to. (Cordite's pressure increases in African heat.) However that solution is said to kill at one end and maim at the other.

Ah, one of those older lower pressure rounds. Lots of modern cartridges run around 50,000-55,000 PSI.

With that much surface area on the base of the bullet you don't need a lot of pressure .

You gotta make the first shot count, 'cause you're to far away for a second try!

Actually he wrote that large dangerous game was usually shot at quite close range, perhaps 50-100 yards or less. It isn't fearful and skittish like antelope that keep their distance. Earlier elephant hunters such as Bell had been able to take long shots with small caliber, flat shooting rifles because the big game fed in open country, but hunting pressure had moved it into brush for concealment which made longer shots difficult and rare. I've seen a tame elephant in a forest, unless it moves or you see the outline they show a featureless dull grey or mud color that blends into the background. Their long legs resemble tree trunks.

Many wild animals can be very hard to see without practice, I nearly trip on the fairly tame rabbits around my house. In the game park at Stone Mountain GA the deer lying on pine needles were invisible even up close, their hair looked so much like the needles that I couldn't follow their outlines, only see their hooves, eyes, noses and most clearly the flies buzzing around them.

I cut firewood in a forest that paintballers used. Tanned white skin and honey blonde hair are pretty good camouflage in long dry grass. Brown skin worked well but black skin stood out at a distance, as did discarded tires and batteries.

Oh, there is no question that those older big bores carried a lot of energy. A Sharps 50 (and other rifles) killed a lot of Buffalo.
