nGen Filament, Olsom Block and Front Door ...upgrading the UM2ex

I'm upgrading my Ultimaker II extended.

nGen

Up to now I workes with the Colorfabb PHA/PLA mix. It's very accurate and thus I found it to be very reliable. (Their shipping options of DHL-Express and UPS are a mess. Both are pure Business2Business courier services and are not fit for delivering to home addresses AT ALL.)

Now I ordered 4 large spools of the new nGen filament to use with mechanical parts.
It's supposed to be even more reliable and that's my primary criteria.

• UM forum thread about experiences (German)
• nGen page lists it's 85°C glass transition temperat

Olson Block

I'm also upgrading my Ultimaker II extended with an Olson block, a set of nozzles and a steel nozzle.
I hope to be able to do thinner layers with larger nozzles (at the same, minimum flow rate) and finer horizontal detail with finer nozzles as well as give copper-fill a try with the steel nozzle.

ABS

I also ordered a front door for the printer to try ABS and Acetone smoothing for non-mechanical parts that require a perfect surface finish.
