Not tried that. TBH, I didn't know what it did or what it might cure. I'll give it a try on the next job.
No, I'd never come across it before either ( Thanks Richard).
It definately seems to work though :D

Just a simple test.... an 8 x 5.5 x 70mm pcb stand-off that I'm printing for a friend. The one on the left is 'standard' and the one on the right is with ironing and monotonic on. The top surface difference is amazing.

The latest batch of 30s/40s figures from Dean. I've replaced a couple of the very fine, flimsy parts (gun barrel and oil can nozzle) with brass rod as I know what will happen once I start using them

Rik, are your friends posing in costume and position if their own choosing or is this for your benefit?

A bit of both. I told them to imagine they were waiting for a train or in conversation on the platform. I think you can tell that we are thespians, though ... :lol:

Just putting the finishing touches to the latest to roll out of the he PLR workshops. I've rescaled the 0-16.5 GVT Glyn to 15mm. A bit more titivating before she's ready for the paintshop and awaiting delivery of some li-ions, but I'm quite pleased with how she's turned out.

I like the look of the GVT tram loco Rik. What resolution did you use? I have used 0.1mm layer with good results, but I have seen a video on Youtube which suggested that due to the rule of 2 (related to the angle of the turn of the stepper motors I believe) that 0.12 layer gives a better result. I'm not sure if this relates only to cura slicer. I'm new to 3D printing, so still learning.

It is a magnificent loco, but those lines would keep me awake all night! Without the rivet detail there should be a way of smoothing the surface.

When these are painted up most of the line seem to disappear, however Peter I do agree with you, and it is what has put me off a 3D printer, I am not sure I would be happy with the results, for external (to model) parts.

It is a superb looking model with obviously some impressive drawing, but like the others have said, as it stands the sideways smears off the rivet heads would annoy me too. Having said that, (a) Jimmy is correct that paint can lose much of that, plus (b) I have found myself that the photography/lighting can make it look a lot worse than it is.

At a practical level, I don't know how Rik has designed the 'kit', but I think I would have been tempted to make the tank sides, back and front as separate sheets, printed flat and subsequently glued together, which would have largely solved that problem.

Hi chaps
Thanks for the feedback.

Regarding the resolution - I think it is 0.12. I'm away from home at the moment (visiting a couple of ng railways in Lincolnshire) so can't check but I used the default which Cura provided for my printer and filament (both Eryone).

Yes, this was a bit of an experiment. Normally, I would print slab sides like this flat but it worked out ok to print them vertically in 7mm scale so I thought I'd give it a try in 15mm. But, as you say, the ripples produced from the rivets is a right PITA.

I've got a couple of options - I'll try smoothing the sides with the rivet detail intact. However, if that doesn't work I'll file them off and replace them with nail art gems.

For info, the loco body took 21.5 hours to print, by far my largest single print

Thank you Rik. I also have printed most of my parts on the flat, although I have tried a couple of vertical prints but without rivet detail.

The latest way ive managed to get around the stirations (ridges) is to give it a good sand with 120 and 240 grit then lie it on its side and give it half a dozen coats of the tamiya painter filler in the cans and sand flat. you can get quite an achievable finish. at the end of the day 3d printing isnt really any less work then scratch building it just changes the nature of the work involved :twisted:

It's taken a while, but the loco is now more or less finished. A bit more detailing and she'll need a bit more weight. I think I may have to raise her up from the track by a few mm - although the height of the skirt above the rail is prototypical, my track isn't. I'm really pleased with the Micron MR603 receiver. Very fine control , maybe even more so than its Deltang predecessor. I've made a video which I'll post in due course.
