3D print: 7 mm "tree" crumbs / water / painting roofs
Posted by Mr Abac on Monday, May 13, 2019 2:00 PM

I'm not a modeler, but I have a few model scenery questions. I want to print a 3D model of my apt complex. Based on the dimensions, the scale will be 1:1450 or so.

1. A 10m (30') tree would be 6-7 mm. Are there any foam "crumbles" (perhaps normally intended to represent shrubs) that size I can buy from model stores?

2. I want to represent water areas with a bluish, slightly reflective (mostly flat) surface. What are my best options?

3. Houses (about 1 cm in size) will be printed in one color, but I'd like to paint their roofs in a different color. Is there a method or trick, so I can quickly paint the topmost surfaces (roofs) of small "buildings"? By quickly, I mean not "individually" paint each roof with a brush.

A tiny bit bigger:

People use epoxy resins for water, but that may not play well with 3d material.  Woodload scenics also has some water products.

How much water are we talking about?  For a small pond I used modge podge

Thanks. I can't tell from the Woodland photo: do these shrubs come as separate "granules" that I can just sprinkle around, or is a big sponge mass that I need to separate by hand?

I'll try a thin layer of Woodland water. I just realized, at 1:1450, water would basically be completely flat.

I thought of a way to quickly paint multiple roofs: dab a sponge in paint and gently touch the tops of buildings, so that only the roofs are affected.

Based on the dimensions, the scale will be 1:1450 or so.

Just to clarify, for the tree height, do you mean cm? and not mm?  

7mm is just a little over 1/4".  That doesn't seem right.

I think the water could be done with paint, on a smooth surface, with a gloss top coat.  Like what Dr Wayne did on his river.

For painting the house roofs, your on your own.  Even if you "bunch" them all together, and spray or bush from the top, your still going to get roof paint where you don't want it.

Just how many house are you talking? that's too many to paint one at a time?

I haven't done architectual models in a long time. 

There are web sites and suppliers that cater to architecual model builders.  You'd have to search around.

Hi Mr Abac.  And I thought Z scale is small.  Perhaps some of the pre-made tufts on the market, like Silflor might work for trees and shrubs.

Clear acrylic sheet like plexiglass painted on the backside with your color of choice is an option for water.

Guessing you don't have an airbrush, maybe spray paint would work for the roofs, but there's the masking to consider.  With a steady hand painting by brush might be the quicker method.

Yea, I'm all wrong in my post.  N is 1:480, the OP is talking about 1:1450 !  Huge difference, my bad.  

I edited my first post.  

So his trees are only 1/4" tall?

Uhhh, N scale is 1:160, but whatever, we get the general point.

To the OP, there isn’t much in model railroading that is 1:1450. So any model railroading products you use will likely be in very small amounts. Trees are likely to just be small pieces of ground foam, water mod podge or something similar, and for the roofs, you could mask and use spray paints/airbrush, but brush painting may me simpler.

Uhhh, I guess...

I assumed we all know N scale is 1:160 (or at least do after reading my post)

Whatever, can’t remember what I was thinking when I wrote that...

At thay size,  i would use woodland scennic medium ground foam and stick one granual on a piece of magnet  wire to be a tree.   High gloss paint would suit water.

 

You could print the house and roof as two separate pieces.  Print one a color. The other another color.   Then glue together
