Another two nemma 24 endplates coming off the production line. Seriously though an end plate will take about 2.5 hours to print with a layer height of about .2mm and a nozzle of .35 mm. You also need a heated bed to about 110C for ABS and about 60C for PLA plastic but PLA is not suitable for temps higher than about 60c as it softens.

I don't think converting a cnc machine is viable the feed rates are a lot higher with 3D printing. For those that are interested look at RepRap Forums there are plenty of self builds. Re the pics the one made with screwed rod is a Prusa and the other is a mendel90. All the plastic bits were made on the Prusa for the M90

Have you tested their filaments? Printing with ABS filament is fairly straight forward; although compared with PLA, a heated print platform is required. Remember that the first layer is bonding with the print platform. If the print is not firmly attached to the platform, the print will fail. Anyways, I got 12 spools of ABS filament in a Saver Pack deals at 3d2print.net for only €299,95. So far, I never had any issues with melting point.

So how’s it building your first 3D printer ? My brother also owns an Afinia-3D-printer; he assembled the machine so easily. Anyways, have you also tried your first print? I remember when we first tried it out, we used filament like this http://www.3d2print.net/shop/3d-prin...ylon-filament/ and the Eiffel tower as the model.

Anyways, have you also tried your first print?

According to the books I have printed and sold 1137 items at £3.95 each incl. The printer required one new nozzle assembly and now has an annoying habit of stepping all 4 motors when it is supposed to be idle. I can work around that but without new toy enthusiasm I doubt I will chase the fault.

Plastic choice in ABS seems to be between pukka CIBA and cheap Chinese, quite honestly the cheap Chinese seems to stick to itself better, choice probably depends on how long the plastic has to cool down before it is revisited by the nozzle.

Lifting at the corners when you print a large flat base is a right royal pain in the bum, I never got anywhere trying to fix that one, nothing I tried worked. Once it starts to lift you can never develop a criss cross pattern, it just lifts in to the nozzle smears to a solid fill and gets worse.
