Update: 3d printed autoclavable parts

I've talked about this with a few people in here already, but got some answers and suggestions from some people in my other hobby communities and have a lead on cureable filament that won't deform at those temps. The tricky part is it has to be plastic (maliable) at extruding temps, which is where the curing process comes in. Always working on some designs for work station bits. Holders for iso, scalpel, tweezers and such. Risers for plates and jars in SAB or FH, and a few other things bouncing around. For bits like this, autoclavable may not really be needed, so thinking may ABS so I can use acetone smoothing to remove all texture from the surface. I know ABS can Leach toxic stuff into food, but for a holder it should be fine and, while it wouldn't survive a PC, you could iso the shit out of it and keep it next to your work station.
More info and designs to come as I finish\follow up with them.
Again, as always, hit me with ideas if you have them.

Why 3d print? Just design your stuff either via sketch or CAD and then have the parts machined via traditional methods. If the designs aren't overly complex it probably won't be too expensive.

no way you can make parts cheap enough or quality enough with 3d printing. Use the printer to prototype your parts then get them made through injection molding. most plastic will warp or deform when put to those heats and pressures. gotta have the right design, material and have some tolerance for warp. not all plastics are autoclavable. This is my industry. Been making plastic parts for 12 years now

One of us are very confused. Why in God's name would I want to have a fabricator machine parts for me when I can make it myself for literal pennies.
and yes, annealed pla tends to shrink in the x and y, and expanding the z. Knowing that you design it with in mind to account for it, or just design it so that slight shrinkage and expansion does not matter. Once annealed the warp or defamation will pretty much be nonexistent. We're not all plastics are autoclavable. which is exactly why I'm doing this, to find out which filaments will work for me and which ones will not. I've talked to people who have done exactly what I'm talking about, both with annealed pla, nylon, TPU, and even ABS though not autoclavable. I build 3D printers, design and print commission 3D print works, and I grow mushrooms. I see absolutely no reason for me to not combine those. I'm not trying to start a business here. Just making custom things that work for me in my setting. some people have expressed interest in this, which is why I keep posting updates. By all means if you have a better way or method continue doing so.

Out of curiosity, did you design a holder for your scalpel and pay someone to machine it for you?

I thought you were talking about mass manufacturing. which is why i brought up injection molding. I was only trying to help considering this is literally my job to assist in the best form of manufacturing with the least hassle, time and cost. If you are one-offing a few parts yes 3d printing is best. and yes I can design in 3D, print, CNC machine, and make molds.

I use a baby food jar with iso in it to hold scalpels. If you're smart enough to even use a 3d printer you're smart enough to not overthink this shit and use the printer for bong and gun parts instead

Word, I see. I used to do some molding and casting for quadcopter and RC parts. I do a lot of D&D figures and tilesets and things like that. If I come up with a design for a part that I really like and need more of, it would not be difficult to mold and cast it in resin. But for right now, I'm just looking for a little bits and pieces to make my life a little easier or more organized in this hobby. Everything I do is extremely customized to my specific setting and scenario. I never really meant to live that way, it's just kind of how I've learned to live.
months ago, when I very first became a member I had mentioned 3D printing in the pub, and somebody was talking about 3D printing a pressure cooker. I feel like that would be absolutely insane,even in stainless, but for things like holders and racks and clamps and risers filter holders and anything else that would be more of a desktop thing and could be sanitized and not really needed to be sterile is what I looking at. But if I can get something to hold in the PC, that wouldn't be bad either. A rack to hold syringes in PC would not be necessary, but it would be neat and organized and helpful for efficient use of space.

I also use a baby food jar to hold ISO to put my scalpel in tweezers. A stand to set that jar as well as my sharpie and small holder for the cotton swab and some tape in any other bits and pieces that are laying on my table would make it much more organized, less cluttered, and just simply make me happier. bongs don't work that great unless you use nylon filament and even then, meh. However I printed lots and lots of dugouts and they sell very well. Fully customizable in every way. Keith and stash boxes. Grinders. Keychains with stash box. Pill holders. Gun parts are different.
you say that as if though this is a taxing or tiresome process for me. This is my hobby. I do this for fun. Why would I not want to think about it.

You're just making prototype positives with the printer. You don't smoke out of pla nylon or abs pipes.

Pla and abs, no. You can with nylon. Either way, this is not the purpose of this thread. I will leave it here for the people who were discussing this. I will post another update when I have actual designs and prototypes in the works.

By your own admission the parts you can print for pennies don’t meet the requirement of surviving an autoclave. So sure they only cost pennies, but they don’t perform their job, and that makes them worthless.

When did I say that.

I know I mistype sometimes but I definitely did not say that it could not be done. In fact, I know that it can from the people I have talked to who have done it ....
Seriously, what are you guys reading and where is this coming from?

For real, feel free to hate me all you want. But this has been nothing but one person after another trying to poke a hole, I address it, and somebody else shows up with a new hole. you don't like my idea that's cool, I'm not asking if it will work, I'm telling you what I am doing.
I also very clearly pointed out that not everything I am making is meant to be autoclave. That is just the next step in this process.
It's a regular Gish gallop in here ... Lol.
