3D Printed Nozzles?

Aside from the porosity of PLA and most other filaments, has anyone tried a printed nozzle? Thingiverse has about a handful of them posted online, but you can just tell that whoever made them lack the underlaying desire that we do on here. I however decided to download one of the more interestingly designed ones and give it a go. I gotta say that it was definitely a unique design.

This one has threads on the bottom for connection to a shower hose so a good start. It’s about 7” long and around an inch in diameter but getting it going is a bit tough because of the open ended design. It’s shaped basically like the business end of a CO2 fire extinguisher. The water runs from the bottom inlet internally thru the walls (that’s what she said lol) and comes out through about 8 tiny holes around the top opening ring spraying straight up. The shaft of it is hollow with a colonic tip sized hole back down at the base of it. While it does give quite a unique sensation, there is no retention possible with this design. Also, unlike a colonic tip, there is no obturator to assist for an easy insertion but I think if you prep with a pregame enema it’d make getting the fire extinguisher in. Anyone else had the chance to use a printed nozzle yet?

I partially like the idea of 3D printing. My biggest critic is about the fanatics, who just want to 3D-print anything and waste a ton of plastics on bad toys while a good mechanic can actually solve the problem. On the other hand, one can just manufacture a lot of things "easily"...

On the porosity of PLA and most other filaments: First of all, there are different ways of 3D-printing, there also is a laser-based technique, where a thin layer of powder is locally melted. This is based on resins and some of the things manufactured this way look quite nice. Regarding the PLA: I believe one could improve at least its surface quality using some solvent vapor, but this is again lots of playing around with potentially harmful chemicals like acetone 😢

Anyways, it's an interesting topic

I have a couple models. I print in either ABS or TPU and vapor smooth before use so they're watertight-ish and smooth. I should probably put some of the models up and share them.

Ideally I'd like to get some Acetal and see if I can make some of the larger ones on my lathe.

@Slipperynozzle, how about posting a picture!

@DoctorGyno, I would not worry much about Acetone as it is used everyday for like finger nail remover and your own body produces Acetone.

@Master_Dorson You're right about Acetone, it's used a lot and your body produces it. Still, you really shouldn't drink it and if you get it into your eyes you have a serious, permanent problem. For that reason it has been replaced in many finger nail polish removers by ethyl acetate

I printed a few in PLA. Always wrap them when I use them.

Oim still setting up my 3d printer. I've made all my nozzles from delrin on the lathe but wondered about printed nozzles. Can they be polished? The hoseman
