hmm, I have one (Wanhao) and in my view the mechanics are very poor and difficult to retrofix and the firmware not easy to upgrade without a great deal of faff.
That being said it turns out reasonable prints provided you are content to be constrained to 'not quite' engineering plastics.
Secondly, seems rather expensive, so unless you have a burning desire to unload 300 notes do a quick search for Creality Ender 3, should be sub 200 and possibly less (got mine for 160) from a UK supplier. Mechanics much better and upgradeable, but same problems with firmware upgrades. Your expectations need to be along the line of Chinese mini lathes, they will work reasonably well after you have spent some time fettling and retrofitting the junk components with ones that actually work.
If you only want a machine for pattern making then you wont need to print high temperature material like PC and POM so firmware changes not an issue. BTW, I have seen low temp wax filament becoming available if you wanted to use total loss moulding.
