Putting Acrylic Teeth into a 3D Printed Skull

I've done this many times before on the cheap plastic skulls, but I've never tried it on a 3D printed skull. With the 3d printed plastic being a different type (PLA) and laid down in layers instead of injection molded I was worried it might not be as easy to grind down and glue, maybe even crack when I tried. Wanted to try tooth replacement on a test subject before I used it in a larger projects and had issues. You never know how an unfamiliar material will react to tools and techniques that work for other materials. The plastic did react differently, but it turned out to be in a good way. The PLA doesn't wad up so bad on the grinding bit like injection molded plastic does and it seems to be a bit harder, so I didn't have to be quite so cautious not to take too much off as I would with injection molded. I also found that the PLA will melt some just from holding the tip of a hot glue gun against it for a couple of seconds and that was helpful because I could soften the plastic, press a tooth into it to shape it, then let it solidify and glue the tooth on.

I do this alot! I make make rigid foam skull and blow out the teeth then plug in acrylics with roots on them from Amazon or Ebay. I even molded a set.

I made a skull mold that I pour plaster of Paris skulls out of. I used the Lindberg skull model for the mold. The teeth are not that strong because I didn't place enough mass behind them when I made the mold. It was my first time making a mold like this of Smooth On silicone. They turn out looking great and I actually like the look when a few or even all the teeth break off. I've experimented adding some fast curing cement and that really adds a lot of strength to the skulls. I'll have to remember to use this method of adding teeth to the ones that I want to be there.

I’m loving the detail of the skull 💀 ❤

@devilman2465 4 месяца назад

It's a good idea but personally, I think skulls look better with some missing teeth.

Hey this was actually super cool came out really well, nice work

@mikeenyart9632 Месяц назад

Looks great.

@tracemiller1519 4 месяца назад

That turned out really nice, I used those same teeth from Amazon they work great 👍🏼 although they are pretty big for some of the posable skeletons

@OakLaneCemetery 4 месяца назад

Yea, the poseable skellys and skulls are always a little undersized for "life sized." More like petite sized.

@tracemiller1519 4 месяца назад

@@OakLaneCemetery yea they were just a tad bit bigger I was doing it for the impaled corpse you made but I made it work!

@pennywalker8910 3 месяца назад

Next make a pirate skull put a gold tooth there

@kristygleeson6979 4 месяца назад

I wondwr if a file pattern could be found for a full size skull that has no teeth but spaces for it. I hate grinding out the teeth. I dontbhavebthe patience lol. You did a great job! It looks awesome!

@OakLaneCemetery 4 месяца назад

On my wish list is an STL file of this one with the teeth removed and the proper indents already in place. I don't have any 3d modeling skills myself (yet) though.

Working as a dentist part time now? How did you manage to print it without a ton of supports?

@OakLaneCemetery 3 месяца назад

Printed it facing up, and it didn't need much support other than under it to ensure it stayed stuck to the plate. Went with what the Bambu slicer wanted to do with tree supports and let er rip. Came out with one support for each cheekbone, a couple under the teeth, and a few up inside the nose that had to be pulled out in pieces with pliers.

@syrkresvlos8831 4 месяца назад

With some simple modeling skills, do you think it would be better to remove teeth from model before printing?

@OakLaneCemetery 4 месяца назад

Most definitely! It would probably take a few trys to get the empty sockets the right shape and depth to match up with the teeth. They don't have a "root" to them so they need to have a surface to be glued against, but still be slightly recessed so they look like they are coming out of the bone, if that makes sense.
