Thumbs up on making progress I hope I can purchase one when they are available
I've been studying pictures of the original JP t-rex and I'm experimenting with scales that I think match it better. They're smaller and smoother. A couple of print tests make me think these can print well. I still need to experiment with painting to make sure I don't lose a lot of detail.

When I like the way it looks. I don't get that much time to work on it, so no clue how long before it's ready.

So, by Sunday then?

I appreciate the straight shooting.
Now get to it!
Quoted from Buffett:Theses are AWESOME!!!!!!!!!!
Ready to buy one.
Cash in hand.
sent you a message.
Peace

The 3D printed version is still a work in progress. Nothing is for sale at the moment. I can say with relative certainty that it won't be available before the end of the year because I won't have much time to work on it.
Just as an update to all interested parties, this is the place I make announcements about this project. If there is news, it will be posted here and probably only here.
I have nothing to report at the moment.
It's still a work in progress with some decisions to be made before it's ready.
winteriscoming I'm missing half of the top teeth, and I'm about to lose another one (or two). Do you have any spare teeth?

Are yours deteriorating? Mine havent at all. I thought no one had...
Quoted from Chitownpinball:Are yours deteriorating? Mine havent at all. I thought no one had...
Yeah. No issues with teeth here either. I had to check mine after seeing this message.
I'm not the original owner, but it looks like the top teeth tore into two pieces, with the right side falling off the Trex at some point. I'm not sure how/when it happened, or if it was the fault of the installer. All I know is, I need some new teeth!
I have an animatronic sculpture I made out of this same silicone that is about 11 years old now and I don't see signs of deterioration. I don't think it's a matter of deterioration. I'm not sure what would have happened to cause a set of teeth to start coming apart unless they've been under stress at an area that was cut. As far as I'm aware, the top teeth in this application aren't really under much stress.
I unfortunately do not have replacement teeth available at the moment.
My demo of ZBrush long-since expired. Since that time, I've had very little time to work on this, and no interest in buying the full version of the software (will I even use it when I'm finished with this t-rex?) However, I noticed recently that they offer the 2019 version of the software on a monthly subscription, so I bought a month and plan to wrap this up.
I'm likely going with larger scales on the jaw and other areas for better visibility. The really small scales on my last jaw test look nice, but blur together from a short distance, meaning there would be little point in there even being scales if you can't see them (like the smooth stock t-rex).
Anyway, the latest model is ready for test prints to confirm whether or not I want to do anything else.

Nice! Have you ever considered to add tiny arms?
Quoted from Davi:Nice! Have you ever considered to add tiny arms?
There was talk of it in this very thread. No one liked the idea.
I don't think they would add much, and could be a hindrance to bending down.
Quoted from j_m_:which 3D printer are you using? because even your draft print looks amazing
It's a CR-10S. It's the only 3D printer I've owned, but it has convinced me that 3D printing is a viable option for this kind of application.
Quoted from toasterman04:is there a list to join? i would be interested!! what are you thinking for time frame and price?
No lists. I'm really not sure on timing and pricing.
I'm still experimenting with options for teeth. Here's an example of 3D printed top teeth. These are different than the previous PLA teeth I did which were printed flat and treated like the paper teeth I have been trying as well. These teeth are sculpted 3D teeth that are kind of like dentures that get screwed into the roof of the mouth. If I can ensure these teeth don't make contact with the ball or the pf, this might be a good option for top teeth. They would be readily reproducible if the need came up down the road vs cast silicone teeth.
IMG_20190408_2131561 (resized).jpgWould the 3D printed teeth work with the original trex? I might buy a set to have on hand. Ive been nervous about my lower teeth lately, they seem to be getting pinched between the metal of the bottom jaw and the sculpted jaw. Just a thought.

Sharp! (pun intended)

Unfortunately, likely not.
For the top teeth, the inner shape of the upper part is different enough between the 2 that I probably wouldn't fit. The cast t-rex also does not have the threaded hole for the screw that holds the 3D printed teeth in.
The bottom teeth are going to have to be much thinner, and probably much more flexible than PLA, so it remains to be seen whether or not a solution for bottom teeth will also work for the cast t-rex.
I would think a paper teeth option could be made to work with the originals, but I haven't tested.

Copy that bro, thanks for clarifying. Fingers crossed I never need them.

This is amazing. Well done.
I've said it before and I'll say it again: It's really cool being able to work with 3d models and print them. In testing I came to the conclusion that the bolt hole and the recessed octagonal hole for the mating lock nut for where the jaw frame gets screwed onto the jaw needs to move forward a tad. In the 3d model, that was maybe a 5 minute job and I'm able to send it to the printer to wait for the results. If I were to need to do that in a hand-crafted model, it would have been a huge ordeal, to the point that I'd probably end up re-sculpting details around the existing hole rather than attempting to move the hole, or I'd maybe settle and not make such an adjustment.
