Newbie resolution question
Good evening all
I'm thinking about the purchase of an original MK2s and have no experience with 3d printing. I would buy an original not a clone or a clone of a clone. 🙂
The primary use would be for HO scale model railroading. Structure walls, doors, windows, H beams and columns, etc. Most prints would be straight, flat and/or square. The window below is a typical example where the window bars are only a millimeter.
Is this resolution and straightness achievable? Or would the resulting prints require sanding and straightening?
I do not expect the brick work to be printable.
Thank you in advance
John
Re: Newbie resolution question
Everything you mentioned can be printed with very high quality using an Original Prusa i3 Mk2s and correct settings from a slicer. There are many prints that you can find online that have very intricate detail and are very possible with today's market of printers. The Prusa i3 MK2s can print as low as 50 microns per layer which is .05mm. That means after 20 layers that 1mm window frame would be completed which ultimately means yes, you can print that after some practice with 3D printing.
Source: I own a Turnigy Fabrikator Mini (Chinese printer) and have been able to achieve .1mm prints very successfully and with great detail. Also the printers build volume at 8cm X 8cm X 8cm practically forces me to print small detailed objects until I receive my Original Prusa i3.

depending on your setup some tiny amount of filling/ post fx may be required, depending on how fussy you are : standard prusa/ e3d nozzle is 0.40 mm wide ( can be swapped down to 0.25mm if need be and prototype 0.15mm but you trade speed for quality, (also heard can be a bit finicky at smaller diameters)
Re: Newbie resolution question
also your workflow is important, if you want it nice and smooth, place the visible face down on the bed, you will get the best finish, if it has a step consider splitting it into two separate layers, Plastiweld aka (Dichloromethane / Methylene Chloride ) solvent welds PLA perfectley ( also good for styrene and other plastics)
i have used my prusa for slightly larger models, and ill post some photos for ya of the result)

Another example of a .1mm layer height print from my Fabrikator Mini, cant imagine the Original Prusa i3 with fine tuned settings on the slicer:
PS: Don't mind the horrible print quality on his head, terrible mashup from someone on Thingy, I should of inspected the print before printing. 🙄

Re: Newbie resolution question
FWIW, I also got started with 3D printing to print parts for my model railways (there's one here: ) simply because model buildings were very expensive and if they didn't make it, you couldn't have one...
As it turned out, after 3+ years, I still haven't printed anything for my railways - just haven't had the time...
But to answer the question, yes it will print what you require, including brickwork; there are occasions where you may need to tidy up a little, but that's no big deal.

0.10mm layer, sorry whites ill i got so does not come out in photos too well
Re: Newbie resolution question
Good morning all and thank you.
Neil - the windows are perfect and you made my decision to purchase a printer easier. I really appreciate your effort.

Re: Newbie resolution question
its worth the wait.. in the meantime pick your poison of modelling software, i use designspark mechanical and zbrush sometimes.. have a play about with making some stuff (if you haven't already )
