I would like some advice about measurements and scaling for 3d printing.

Hi folks,
I hope this is the good section for this?
I decided to take a plunge into making humans with a digital program: makehuman, and 3d print it.
The first 3d result is encouraging but not up to my taste, it will need some more work.
Probably i was mixing up scales?

Now my main question is how long would a human be in scale 1/gauge 1?
If i take the average human length of 180 cm and divide that by 32 i come to a length of 5.65 cm.
It looks out of scale of what i printed in comparison with tracks, wagon and loco.
Or was the proper scale 1:29 that would be 6.2 cm?(seems more logic.)

Any advice is appreciated, thanks in advance.

Ps if someone want to have those stl files or gcode files used for a 3d printer, i would be happy to share, after some corrections.
 
I suppose it depends what you mean by Gauge 1. 1/32 would be about right if you were running standard gauge rolling stock on 45mm track, but 1/20 would be nearer if you are running narrow gauge stock.

Yes please. I would be interested in 3d drawings of figures. I've just invested in a cheapo 3d printer and figures are on my list to explore.

As Rik said, it all depends on the type/scale of equipment you are running. Usually "Gauge-1" is taken as 1/32nd or 10mm:ft (1:30). But study this chart and let us know which size loco you are comparing it with.

For G scale, nominally 1:22.5, I use a Credit Card to gauge any figures I buy for the railway....

Thanks for the chart, that was very helpful/informative.
I go with standard gauge because that one is the most common.
For broad gage (5 foot Russian)and the meter (south of America and Africa) gauge locomotives i am going to keep the 1:32 scale humans, to get a even more even uniform look, probably i will make them from 5,8 to 6.2 cm and keep this.
And the loco i printed was for a fn3 scale :blush: the wagon for 1:32

Files are coming, after correction.
I will try also to get you some sheeps :angel: if my memory serves me well?
Dont forget to enable: contact with platform.
If you are going to print with pla, in the full sun the can shrink your item 1 to 3%.
Rattle my chain if you run in some difficulties.
 
if you go with "Spoor 1" (1:32), the average person (170 to 175 cm) should be 54 to 55mm high (if standing straight)
3D printing figures in that scale? i hope, you got a very good printer.
i tried that with a XYZ all-in-one printer. wan'na see results? here:

This is the view topic advanced forum page. an old dog, trying to learn new tricks... here i will share my experiences with the new tecnic of 3dimensional printing. i bought me a DaVinci all in one printer. to set it up was a real bitch. not the hardware. apart from missing parts and...

well, meanwhile there are better printers.

IF your printer recognize gcode, i changed also the settings.
0.06 for finer detail and 50% infill, made them a little taller and put a board under them.(6cm)
Assuming you have a standard 0.4mm printhead and work with 1.75mm thick pla filament and heated bed.
3d printing is a adventure.
I tried several programs to run on my laptop and the level of difficulty, and ended up with 3d builder from windows itself, downloaded some files from "thingiverse" and use the "slicer" program that was provided with the 3d printer.
Programs like 3d rhino and fusion360 are to expensive and to heavy for my laptop and wallet.
Tinkercad is also a nice program but to limited for my wishes.
Hope this could help you a bit to help you further on the road.

korm kormsen korm kormsen ,
Your results are looking very good and promising.(back in 2016!)
I am by no means a expert and still a rookie in 3d printing, but i think you already did this discovery: I think your infill must be higher(50% plus)
and i think your flow must be set to 100%
I have a "ender creality 5 plus" with full options.
I hope, (if i may be that brutal(if not, i am sorry)) i would like to have those stl files. Humans are hard to find.(in 3d :rofl: )
The program: "makehuman" has also its limits.
Thanks in advance for your tips hints and links.

Thanks for that - yes my printer (a very cheap (£80) Anet A8 clone), has a 0.4mm head and uses 1.75mm PLA. It recognises gcode as well. I'm even more of a rookie and so not yet tinkered with the printer settings. I did wonder if they could be changed.

My slicer program is Cura which came with the printer and I've been playing about with SketchUp - which, let us say, has a very steep learning curve. I have, however, managed to draw and print some seats for a railcar I'm building, so gradually getting somewhere.

I've run out of the mini spool of PLA which came with the printer and have ordered more, which means I have time to tinker until it turns up.

even then, i expected more.

yes, more infill = better quality

my XYZ printer has very basic settings. no flow regulations.

i will definitely not send you e-mails with hundreds of attachments. go search by yourself.

use yeggi - 3D Printer Models Search Engine

set to "free". and "popular" or "latest".
searchwords i use (one by one) for humans are figure, man, woman, male, female, boy, girl, kid, baby,
mostly one finds either 28mm gaming figures and nudes in different scales.
the 28mm figures printed at 200% are just right for spoor 1. the nudes you must observe closely to find out, how to down or upscale. :giggle:

or you look at my profile on thingiverse under following.

www.thingiverse.com

korm's Thingiverse Profile

Learn more about korm on Thingiverse.

most of those i'm following are into making figures. go to "designs" they have, and start downloading. (if i remember right, you have to register before downloading.)

ah, nearly forgot Netfabb:

Netfabb | Additive Manufacturing and Design Software | Autodesk

Netfabb is connected software for additive manufacturing, design, and simulation. It converts 3D models to printed parts and helps reduce build errors.
www.autodesk.com

i had been told to use Netfabb. even the free trial version helps. you can use that for scaling, or cutting up objects, or turning them to better position for your printer. AND it can repair .stl files, that are faulty. with holes in the skin. i found out, that processing the files from the net with Netfabb makes for better results.
 
Great confusion here - Fn3 scale is 1/20.3. It uses 45mm gauge track to replicate US three-foot gauge locomotives and rolling stock. A 180cm high human in that scale would be 8.8cm high.

The simple answer to this scale is that it is 15mm to the foot!
 
I'M not confused, but the way that the OP posed the question was confusing. Look - 'And the loco i printed was for a fn3 scale :blush: the wagon for 1:32'
 
So the question was:
Now my main question is how long would a human be in scale 1/gauge 1?
If i take the average human length of 180 cm and divide that by 32 i come to a length of 5.65 cm.
It looks out of scale of what i printed in comparison with tracks, wagon and loco.

So if it (the average human of 180 cm) printed in 1:32 looks out of scale "of what i printed in comparison with tracks, wagon and loco"

Then the simple answer is what scale did you print your tracks, wagon and loco?

I would submit your tracks, wagon and loco were not 1:32 scale. What scale did you print them to?

The tracks are all 45mm in between the rails.
I agree that the aluminium tracks with the thick white ties is not entirely scale true.
Both makers(for loco and wagon) claim that they are 1:32 scale.
The maker of the loco (the Terrier loco)stated also that this was a relatively small loco.

Probably this is the confusing part for me.
I am thankful for all the help, to get me a good start.
The printer was set to 0.3mm thick lines(very low quality) for experiments, incl the rc part.
Next prints will be in 0.06mm thick lines(very good quality) for serious work.
