Hey folks- I decided to see how prints from a Form1 would stand up in the vulcanization process. (I spincast gaming miniatures as a hobby/side business.) I use organic rubber molds and vulcanize them at 320F for 2.5hrs. Now, on paper, it didn’t look like this would work, but it actually worked perfectly. I printed a couple of small parts on Friday and left them in a window until Monday morning so they hardened up a little more. The parts even survived the process. There is a stress fracture in the sprue for the wheels but that was from me pulling it out of the mold with needle-nosed pliers. (The flash on the wheels is because the cavity was not properly vented yet, casts afterwards were perfect.) I plan to try some larger and less flat pieces this weekend! ![](https://support.formlabs.com/attachments/token/zykhbdfewbqxghv/?name=formparts.JPG) ![](https://support.formlabs.com/attachments/token/jjcwiypyzh39t2a/?name=formpartmold.JPG) ---

Joshua - too cool. I have never heard of spin casting or vulcanizing but want to try this! Could you post a short description or tutorial of your steps? ---

Spin casting is how a lot of jewelry, figurines and other small metal parts are made. Vulcanizing is taking uncured rubber mold blanks, sandwiching your parts between them and then cooking them at 320F and a few thousand PSI for a few hours. The rubber expands and hardens (vulcanizes) capturing all the detail of the master. I have a couple of videos, geared more towards my customers, but you should get the idea! ---

This is really fantastic Joshua! ---

Just to prove to myself it wasn’t a fluke I made a mold of another part. Worked perfectly. ![](https://support.formlabs.com/attachments/token/igjkfinktqamf6t/?name=cast.JPG) ---

Now that’s \*awesome\* news!  I thought for sure the SLA material wouldn’t stand up to the vulcanizer temps/pressure!  Are you casting with zinc alloy of some sort?  Now I’m motivated to get my furnace conversion to LP going! 😉 ---

This is great Joshua, enjoyed your videos too. I wonder if your method could reproduce this fairy sculpt I did awhile back? If you are interested and not too busy let me know your thoughts. -Shea ![](https://support.formlabs.com/attachments/token/1ghoicvzieccmom/?name=shea-fairy-render-small.jpg) ![](https://support.formlabs.com/attachments/token/eqoyabkbq51hy7p/?name=shea-fairy-cast-small.jpg) ---

@Clay I cast everything in lead-free pewter. @Shea I could quite easily reproduce that, but with pewter you aren’t going to get that fantastic surface finish without a lot of polishing. ---

I have seen Joshua work awhile back while researching the Spincaster and Vulcanizer before I purchased a set for myself. Joshua is actually doing the same thing I am doing, only I plan to make parts for suppliers and he already has an established business of his own and it is quite fascinating if I do say so myself. Joshua have you tried the I think it is the organic low temp type of molds for your items? and if so how does it or not work? I have a few more questions if you don’t mind being bothered once and awhile… ---

There are a number of low-temp silicon molds. Unfortunately I can’t use them. As you can see in my video I have some green silicon molds I get a friend to make for me if parts are really delicate. I live and do this work in an old warehouse in Oakland, CA. I don’t have a garage or barn so I cook my molds in our warehouse kitchen. The one time I cooked a silicon mold I thought I was going to die. When I opened the mold can there was so much foul outgassing that I got light-headed and almost passed out. I barely made it out of my back room. I haven’t been brave enough to try it again! I am always open to questions. When I started this I had no one in a similar situation to turn to so I am happy to be that guy for those looking to do it now. ---

“I decided to see how prints from a Form1 would stand up in the vulcanization process.” You seem to have trans. resin. Do you try it whit the grey resin? ---

Kevin, I do not have any grey resin. Early on as I was learning my way around the machine I had a number of failed prints. Its so much easier to clean the cured bits from the clear than I imagine it is in the grey. I just clean the metal masters instead of the prints and then make production molds from them. ---

Joshua You say you have some failure print. Did you make some mistakes on the supports or something like that or its the form 1 that its not close to the 100% success print? We currently have a jewlery 3d printer . All the supports need to be designed for each piece 8-S. We are looking for a printer with better results . We sometimes have to restart the same piece 4 times thx for the fast answer. Kevin
