In this Next-To-Last video I'll once again go over what I've determined to be the causes of the dimensional discrepancies I've experienced during this casting session.

I'll also touch on what I intend to do to get my models to print out to the dimensions they need to be in order to compensate for the Out-Of-Round dimensions I've gotten thus far.

When viewed with the expectation of getting perfectly cast bullets out of these test Prototype 3D printed 9MM bullet molds right out of the gate, it's easy to see how one might consider these efforts to be a complete waste of time.

To Me, it's not a waste of time.  I'm trying to do something that, to the best of my knowledge has not been done before; and that is, casting some good usable 9MM bullets using some 3D printed bullet molds out of what some may consider to be plastic molds.

How many of you 3D print fans knew that you could increase the heat resistance of the Siraya Tech Ultra White resin by mixing in some additional Porcelain Powder?

I didn't know that either until I tried it to see if it could be done.

How many of you knew how much additional Porcelain it would take in order to increase the heat resistance enough for the resin to be able to withstand the thermal-shock of molten lead? 

How many of you experienced bullet casters knew that you could 3D print some Airgun Pellet molds or 9MM bullet molds and use them more than just two or three times to cast pellets or bullets with?

I didn't know that either until I tried it myself to see if it could be done.

If I hadn't tried it I wouldn't know how much shrinkage to expect in my prints using the specific 3D print resin that I've been working with.  

I wouldn't know if I could get a complete fill out of my bullet mold cavities without having the cast bullets melt into the mold cavities and just create a big molten lead and plastic gooey mess.

Most of the folks that have been following this project who took the time to post any questions or comments have been extremely supportive. 

You'll never know how grateful I am for that support.

As is usually the case with projects like this, there have been and will always be  those self-appointed experts and naysayers who will chime in with all the reasons they think such a project will fail or is a waste of time.

This 3D printed bullet mold experiment is ongoing.  This is just the first steps toward inevitably getting these 3D printed bullet molds to cast perfect or near perfect, usable cast lead bullets.

Stay tuned. There's still a bit more to come.
