Printing a Mold with a 3D-Printer

Wichtel · Post by **Wichtel** » Sun Mar 25, 2018 1:52 pm

Hi all,

at first please excuse my bad English, but it is not my native language.

I allways liked to read the Inventors Corner and now I did my own little project.

I took Victoria 4 from Poser and I made a mould of the 3d-file with a CAD programm. Than I have printed the mould with the 3D printer and I tested the mould with silicone I had from an other older project.

I just have to check how to put some pictures in my thread.

Greetings Wichtel

Poser to .STL is hard .. what 3D CAD Program did you use to get the .OBJ to be "water-tight" for 3D printing?

I was thinking the same thing lately.
Only I don't own a 3D printer yet.

Are we talking perhaps about modular moulds for full size dolls here?

I think you'll need at least 5 posts to post pictures.

In the upload attachment window below (when posting) choose file, then add the file.

You can put it 'inline' in your post wherever your cursor is located.

Goodluck.

How strange this topic came up.

I was only just having this same discussion with Patrick from PIB.

This is exactly where the market is heading. Especially in China where volume is now the order of business. In fact this is how I do a virtual Marquette for a doll concept. this is how we were going to compare the sculpts for the Agony demon doll concept to the 3D Marquette, and also formed the imagination concept for a certain 160 cm muscle doll on the market

and a sexy fitness gal called Pearl.

Using Blender I can generate a poser file and export to .STL. and then 3D print the image as the Marquette with polygons so far as small as 0.05 MM for a 160 cm scale model, but still room for improvement in that area.

So now refer to this topic

https://www.dollforum.com/forum/viewtop ... 14&t=98328

Imagine that CGI forming the basis for a Marquette for the sculpt or 3D print for a doll mould. Mind-blowing.

So Mannycan has asked about manifolding (water tightness).

This will help you all out, this is a very handy post, I picked up on shapeways.

Trust this post helps.

Digital dolls are dolls just waiting to be made reality!

LOL - no .. at least not for home printers. Small dolls maybe. And that's a big maybe. In theory we could print in NinjaFlex or some other flexible material.

As you guys know from my 3D backgrounds, I'm already pretty versed in CGI. Actually the shadows for a lot of my posts use Victoria 3 or 4 - I just set it to render the shadow only and then superimpose Nadia (or Reetzia).

So that shadow is actually an invisible Vicki lol.

Anyways - back on topic. But I've heard that the conversion from Poser OBJ to STL is a pain and often prone to defects. Is there an app that does this well?

Quickest way I used daz3D to stl is to go direct to Zbrush and create it there. I print 3D dolls as I've made 5 so far in 1:3 and 1:6 scale. These are positives so not for pouring silicone, but for display.

I guess I'll have to check out some z-Brush

So far I only test it with her face.

I will try to make a mask like the RealDoll faces. As I am playing with the Ardruino sometimes I thought it could be fun to add some electroincs in the head later

I gave the poser file to 3dMax and than to Inventor.

But in the moment you can see the triangles in the silicone.

I am looking forward to post some pictures

As it is possible to me to post some pichtures now. Here they are. I am anxious to your comments.

And certainly I will clean the mould better next time.

Very interesting!
Maybe “masks” are the way to go.

This is what's inside a WM-head:

(as shown in this thread)

If you can "easily" make molds for your own custom faces, you can even create faces from pictures
you do not own the rights on, as long it is for your personal use and you don't show it publicly.

Another thing: masks for humans (or dolls). I kinda have a thing for anime cosplay.

But there are not many anime heads for dolls available and high quality masks like this are expensive.

Thanks Wichtel.

Here is a picture out of the CAD program

You could see the upper and lower part of the mould.

I think it is possible to make every face printable, that is offered or made digitaly. You are able to create a face in the face studio of poser. But never the less the texture is mostly the biggest part, that makes you think that that is the poerson you made the photos of before.

But if I manage to make good masks for a "ground-head", i think that would be nice

That's cool - I had thought of printing my own DS skull (because DS doens't have too many oral heads). I'll refer back to this post for sure!

I printed several negative molds with my 3D printer with PLA and poured it with gypsum.
Then I melted out the PLA in an oven and replaced it with tin made for food applications.
After pouring melted TPE in the tin mold and putting it in a vacuum chamber I got my own inserts.
$5 for a TPE insert isn't bad

. I just start creating my molds for platinum silicone inserts because a self-made insert is much cheaper and made to fulfill it's purpose.

Great work! Is the face TPE or Platinum Silicone? Or something else?
