Hi Izzy,
OK, updated my profile. Did you check out my website? (see my signature). Full bio there, together with beginnings of section on my experience with UM2, showing videos of some of the enhancements I have made. There is lots of other stuff there too, covering all sorts of other hobby topics.
Here are some of the extremes to which I have used the Premium ABS:
The first is some very small parts that I designed to make a flexible 'gooseneck' for an LED desk lamp. I printed at .15 layer height and 50mm/sec with 25% fan. Bed adhesion was with the Bostik stick. The slight yellowing is because I applied this on top of a previous layer of the Pritt glue, which I forgot to remove. After several prints, the Pritt does yellow slightly at 95deg, but it still works well.
The other extreme is a folding table stay that I printed a few days ago. This, unbelievably, was printed with 0.3mm layer height, and a lightening speed of 120mm/sec. Nozzle temp was 250deg, bed temp was 95 deg, and fan was off. I used the Pritt glue here, applied on cleaned glass. Despite the large surface area, there was no sign of it lifting, and I did not use a brim. These parts have proved to be very strong, even though I used a 20% infill - but I did use a 1.6mm wall thickness just to be on the safe side.
Just to satisfy curiosity, here is a screen shot of the table stay as I designed it in TinkerCad (my favourite go-to design tool). It shows an assembly of the parts to the existing table's folding legs, which I use to check the final design for any problems. Each item can then be individually exported for printing - just love this software!
The reason I made this thing was that the folding table (bought in Lidl store) had struts on each side that made it difficult to seat 2 people on each of the long sides. This mod has worked out extremely well, and we can now get 6 people sitting around it, and it is very stable.
P.S. Yes, I realise that to be printed correctly the lower part of the hinge should be printed vertically to place the layers in the plane of the greatest stress. But this would have required a lot of support which costs a lot of material, and extends the printing time. Anyway, as I normally give parts like this a strong dose of the 'acetone vapour' treatment, I have not run into any problems yet, even though I have placed considerable horizontal stress to the table. Besides this, there are 4 of these, so if one fails I don't expect the table to collapse. If eventually I do have a failure, I have a few options - print that part again with 100% infill, use 100% infill with an 'acetone dip', and of course print vertically (as I correctly did with the tube clamp part - which didn't need supports).
