[Filaments dissolves in what ?]

Thank you for your 'articulate' answer. 

I'll make small tests has you mentioned. Your answer gives me orientation in the material I can print with. (PLA)

 

I've also discover the Smooth-on answer to my question.

They recommend the coatings of XTC-3D, to protect the model. 

 

I realize that in the modeling world, everyone wants to sell you something that you may not need... Or worse, inappropriate material.

 

[Filaments dissolves in what ?]

HI and thanks for your appreciated help.

I am a hobbyist and I wonder what will happen to my 3D print when I'll try to make a mold with it.

For example; If I use my PLA printed part and immerge it in a urethane based product, or an epoxy resin. Will it melt ? 

 

To turn around the question.  

What filament will not melt with urethane, epoxy resins and silicone ?

That is what I'd really want to know.

 

Regards !

Thanks you for your input gr5 // I understand the idea about stiffness versus flexibility. The part I want to make goes at the tip of a stick. I want to design a outdoor hockey blade. I wonder if any of the filament could be strong enough.

I want to obtain a very resistant part. (Impact resistant and abrasion resistant).

I read about PEHD, HIPS, PC and Nilon, I wonder if one of those would do well with a Creality printer.

I also want to spend no more than 50$ Can per Kg.

Do you have any recommendations ? Thank you.
