    Hellboy bust and matrix mold making tutorial

    Hi,
    I'm new here. Can't say I'm new to sculpting - as a child, plastiline was maybe my favourite "toy". But as an adult sculpting is a pretty new hobby for me. I made a couple of smaller figures when I discovered polymer clay, this one here is my first serious sculpt.
    I wanted to try the whole cycle from prototype sculpting via mold making to the coloured resin cast. I also wanted to have something nice on my shelf, so I started my Hellboy bust...

    It's not finished yet - at the moment I have only some resin plaster castings and I'm trying to find some resin. I's not easy here in Estonia... (Tried resin my friend is using for making canoes and it's not working).

    I took many photographs when I was sculpting and making my plaster/silicone matrix mold. Several people thought it is good idea to post them here, so I will do so. It was the first time I was trying to do this, so of course I made some mistakes. But in overall I think I made pretty good job with it and I hope those pictures can help some other people to demystify this whole mold making process.

    I will not post too many pictures about actual work-in-progress bust. I posted them on Hellboy forum when I was sculpting and most of them are not so important or interesting anymore. One more thing - polymer clay I'm using is German made Cernit, it's the one I can get here in Estonia. There are a couple of more clays in shops here - Russian made one I use sometimes as the first layer of clay on wireframe (don't like it enough to sculpt) and Fimo, which I've never tried. There are many colours of Cernit, I used white for this sculpt. It's not the best colour to photograph but I tried my best.

    Here are some pictures of my Hellboy:

    Let me be the first to say what an awesome job you did! That bust is Mignola all the way and MAN, did you do him justice! There've been so many Hellboy busts put out but I gotta say that yours is one of the best I've seen. Are you selling casts? If so, and it won't break me, I'd definitely be interested.

    Welcome aboard dude and again, great job!

    Wow!
    Nice!


    Tore näha et ka eestlasi siin liigub.
    Eile regasin - huvitasigi just skulptuuride osa, nüüd vaatan et ültse hea koht õppimiseks.

    Kust sa seda savi said? Ja 'moldi' tegemiseks vajaliku kraami?

    troyboy -
    thanks! Like yours sculpts too!

    It's not so easy here, I had a lot of trouble when I was trying to buy some mold silicone... The same with resin. I will make some casts, primarly for myself and I need a couple of them as gifts. But resin plaster I have at the moment is still a plaster and I'd like to get some stronger material.

    One of my main goals was to try to sculpt a Mignola style bust. There are so many film inspired stuff but not so many comic book statues. Even the Mezco comic book Hellboy's face doesn't look like Mignola's drawing...

    Mold making 2 - preparations for the first plaster side.

    I used Russian made plastiline (I will call it clay here), but the water based clay could be better.

    The first thing to do is to define the plane which separates the two mold sides. I'm not very precise here, as this clay I'm sculpting now will define the exact plane which will separate the two plaster molds. It's important to get it almost right, but there is no point to overwork on it, as the time to define the real (silicone) mold will come later.

    The clay won't even touch the sculpt. In fact, I used cling film to cover the sculpt most of the time it's covered with clay - this way I will have much less clean-up to do later.
    So, this is the clay what simulates the second half of the mold:

    Hellboy bust and matrix mold making tutorial

    The next step is to use some more clay and to cover up the whole sculpt. This clay will be replaced with silicone later, it will become the one half of the silicone mold. So, the layer of clay should be not very thin and also not very thick. I think I used maybe too much clay here, could've got away with less silicone later...
    Note the cling film and also various details which will later help to synchronize the plaster mold's sides together (round sockets) and also silicone mold and it's plaster cover (called mother mold).

    It all will make sense later...

    woah!

    That's a real clean, sharp looking sculpt, perfect and completely flawless! Even the mould you're making looks clean and sharp!! Nice one mate

    Mold making 3 - first plaster side.
    There is fabric inside the plaster to make it a little bit stronger:

    Mold making 4 - second clay side.

    Mold and sculpt after removing from the cardboard base:

    Hellboy bust and matrix mold making tutorial

    The clay what simulated the second plaster side is now removed. The clay still there will be replaced with silicone later:

    Hellboy bust and matrix mold making tutorial

    Sculpting the second silicone half. Again, there is a cling film over the sculpt to make the clean-up easier:

    Finished side 2. The paper towel tube will become the hole in the plaster cover to pour silicone in:

    Mold making 5 - second plaster side.

    Here is my mold after the second plaster side was made...

    Hellboy bust and matrix mold making tutorialHellboy bust and matrix mold making tutorial

    ...and after some clean up:

    Hellboy bust and matrix mold making tutorial

    Very important thing is to use some vaseline (or similar agent) on the areas where two plaster sides will touch each other before making the second plaster side. (It's the area with round sockets on the next pictures.) Without it there will be one monolithic plaster shell which is impossible to open. I used some and with the help of screwdriver it opened easily!

    Here is one finished plaster side after I removed all the now unnecessary clay from the inside:

    Edit: it's clever to measure how much clay went for filling the mold, the same amount of silicon is later needed.

    The next step is to prepare the other plaster side for silicone pouring...

    I can't belive I missed this thread! I must be blind, because I was even looking for it. Great work! You already know I think it's great, since I was one of the ppl requesting it! Thanks for posting it! I will be following the process!

    As a sidenote:
    I'm going to see if I can make a summary of the info I got in my thread on where to get materials in Sweden. Perhaps a new thread could be made sticky so that people from other countries could post where they get their materials too. It seems you have the same problem with getting polyurethane resin as I had (have).
