This is my short video clip of the very first casting session with my newly 3D printed single cavity 9MM bullet molds.
The second half of this video shows some closeup views of how each individual bullet mold is holding up thus far.
The 2nd casting session isn't shown because I was in such a hurry to get this done that I forgot to turn the camera on.
My fumbling around with the stuff laying on the table in front of me should show you all how in such a hurry I can get with these 3D print projects.
FYI--You may want to take a Dramamine tablet before viewing the second half of this video. My camera work can be nauseatingly shaky.
I'm hoping that I can presented enough information with this and all following videos to show that if done in the proper sequence, and with the proper safety protocols, these 3D printed bullet molds actually work.
There are still some minor modifications I need to make to my models and my table top organization but I'm confident now that this WILL be a good viable method for 3D printing and casting my own bullets in the future.
Important to note:
The addition of the Porcelain Powder to the factory formulation of the Siraya Tech Ultra White resin did NOT negatively effect the printability of this resin AND, it has indeed appeared to have increased the heat resistance just as I'd hoped it would.
Also equally important to note:
When mixing additional Porcelain Powder to the Siraya Tech Ultra White resin you must make a concerted effort to keep the additional Porcelain Powder mixed into your resin as evenly as possible. This can be done manually by pausing the print periodically and using a spoon or other stirring tool and/or by adjusting the lift height of the build plate between layers so as to create an up and down agitating effect as the build plate moves up and down. I used the latter method to stir the resin as it printed.
As always, any insights, suggestions or questions are welcome.
I'm sure the obstacles I've encountered so far, whether ignorantly self induced or induced by other factors that I had not considered or experienced, could have been accounted for before the prints were even made if I were a trained engineer.
I am not a trained engineer. I'm just a chronically cheap, chronic Do-It-Yourselfer.
I subscribe to the idea of self-sufficiency. If I can make my own bullets rather than spending money to buy them then, this is what I'll try to do.
We're living in a very squeamish and easily offended society now days. Please accept my apologies up front for the one or two cuss words that came out of my mouth during the recording of his video.
To me this kind of language is just a sort of stress management technique that I've perfected over the years.
