Mold dreads

[agh12]

I've made a two-part mold in 3d for printing. I'll try the flexfoam it x because it's the only one I can get where I live. Any help is appreciated.

Will be interesting to see how this goes, but to my knowledge dread molds are usually made in silicone, vs. something hard like the 3d Printer plastics.

 

[agh12]

I have seen dreads made in pretty good plaster molds.
I hope it works out well.
So there is a material called filaflex that is elastic, could work better.

How i do it:

1.- A tube and a sharp stick of a broom:

2.- Insert the stick into the tube. Be careful not to touch the edges

3.- Fill the tube with silicone molds. I am from Spain and I bought this:
Silastic 3481 Base + Ag. de Curado - Feroca Composites, S.A.

4. -wait a day

5,. The result. You have the mold:

6.- I use Flexfoam

7.- You have your dread

Next steps...Paint and put the rings

Great tutorial.
Have a good finish.
Did you use any release agent?How many grams did you use for each one?

Thanks. The proportion is 1:1. To mix them i use a syringe. 20 ml for each component, without any other product. It's ready in an hour aprox. The dreads are 50 cm long

Nice job, It's awesome to know that this worked for you! might try this myself at some point, minus the 3d printer since I don't have one

I always warn people in advance when using foam. Make sure you use it in your garage or a place where its well ventilated with the appropriate protection.
This forum has a history of people falling ill due to foam exposure not to mention permanent damage to lungs. So once again, for anyone reading this and attempting this please use the appropriate protection.

 

[lokutus]

You are rigth. Gloves, mask with gas protection, safety glasses, ventilated place...Every precaution is short

 

[Wreav]

For those reading this just know I am one of a select dozen of individuals who have suffered from foam exposure. It has permanently damaged my lungs, regardless of this safety first! Always!

Great workaround, and very effective loku! I myself went the PVC tube route, minus broom I'm surprised you didn't have too much trouble getting the silicone out of the tube? or did you spray a release agent inside before pouring the foam? Cause I had a really hard time getting it out the first time, then afterwards I wrapped the whole silicone mould in cling wrap before putting it back into the tube. Cling wrap makes it heaps easier to put in and pull out..

..wait, that didn't sound right..LOL

I decided to go for the traditional method, I bought mold star 30 of the brand smooth on and flex foam x since it is the only one sold here.What gas masks do you recommend for safety?With filter or without filter, type?

 

[agh12]

Sharpen a 45 cm stick until you get this result. Next, a mold will be made of various pvc sections. Upload photos soon

 

[agh12]

Any advice with the silicone mold star 30?

 

[agh12]

All ready to make the mold

 

[agh12]

Once glued vertically, as shown in the picture, paste the PVC tube and ready to pour the silicone

 

[agh12]

mold ready. came out quite well.
any advice to cast the foam?
I need some release agent?

 

[agh12]

pvc cut and mold ready to start. some advice on whether to cut the mold or there is no need to cut? any help is welcome

Looks great. and this is awesome idea to use pvc pipe!

 

[agh12]

do I have to put some release agent in the silicone or will not it be necessary?
