Hi UM experts,

 

I have a UM5 and am trying to get the best quality prints for architectural models. The larger scale models, 1/16" = 1'-0" print fine, but the smaller scale, ~1" = 50' does not. A photo is attached. Left print is at .1mm height and the right is at .2mm using pla. Are there particular setting I can adjust to stop the blobs on the piers between windows? Is the detail level/size of the piers to small and thin to get a good print?

 

Thanks,

 

John

Maybe printing the walls flat on their back, and then glueing the pieces together, might give better results? Similar to the HO-model railroad houses we had as kids from Faller, Vollmer, Kibri, etc... Then the material flow is more constant and the print head does not need to travel through air as much.

 

Or maybe you could print the main wall vertically, just like you did now, but print only the windows flat on their back, and then assemble? That might give a better layer line pattern?

 

Also, using sand- and stone-colors (beige, warm grey, light grey, cream) could also help to hide artifacts, and they are very well suited for architectural work. White is often a difficult color to print, and it shows defects quite hard. ColorFabb has a lot of custom sand- and stone-colors. (I am talking about the non-filled, plain PLA colors.)

I would suggest you reduce the print speed to 40mm/s; reduce the print acceleration to 2000 mm/s2; enable jerk control and set it to 15mm/s reduce print core temperature by -10°C. Make sure all the driving straps are tight enought.

Thanks geert_2 and Framar,

 

Flat printing is an option I expect to explore as I do more models, especially for larger scale models with more detail, but for now I am trying to use out of the box capabilities for printing buildings with little or no finish work/assembly. I will try the suggested settings adjustments and let you know how they work.

A 0.25 mm print core might also help but will increase print times though.

Yes, I do fully understand that concern. I am feeling the same about post-processing work; I don't like it.  :-)

 

But printing vertically with lots of retractions, and the nozzle moving through the air a lot, also takes time, in addition to creating the imperfections you have seen. Depending on your designs and your printer, there might come a point where printing flat goes faster, and requires less post-processing than smoothing out these imperfections. So you could get more done with less effort. Maybe...

 

If you plan on doing lots of prints, I think it might be a good idea to print a small representative test in both ways, and compare the time, quality and required post-processing? Or even not print them, but just slice them in Cura, and compare the predicted printing times?

Agreed. I will be working on a variety of scales and expect to experiment quite a bit. Fortunately the main model I will be building is at 1/16” =  1’-0” (1:192) which prints well (still have to figure out detail level a bit). Picture attached. Also a city site model from simple 3d data pulled from the web. The land mass in that scaled so thin it created an interesting mesh instead of solid surface - the accidental result came out really nice!

Hi aubij,

Could you elaborate please about your method of generating the city landscapes?

Hi shurik,

 

I downloaded a 3d file from cadmapper.com setting a height of 20m.
