  • Biocompatible Material

    Hello!
    I am currently working on a project that involves 3D printing in the context of medical devices. So here's my question: are there any 3D printing materials that are both flexible and biocompatible?
    Thanks in advance for any answers!

    What type of medical device? Surface contact, or implant? I'm not going to say that there isn't any biocompatible 3d printing media, but it will probably be difficult to come by and depending on where you are, the governing regulatory bodies may give it extra scrutiny. There are obviously plastics that are considered biocompatible, but even if you use one of those materials from a company that will give you a certificate of analysis guaranteeing its formulation, there may be problems with the fact that you're remelting and extruding that material in layers that could potentially trap foreign contamination. The startup I did work for had to purchase a study to prove the biocompatibility of 316L stainless steel. That is a specific alloy for medical implants, being used in a device that only had surface contact measured in seconds. If you're looking to design silicone implants, you might be able to 3d print your molds for quicker and cheaper iterations. With that approach, you're also back in the realm of traditional manufacturing processes that regulators may be more comfortable with.

    Sorry if this comes off negative. I certainly don't want to discourage innovative ideas. 3d printing does offer some options that aren't available using other manufacturing methods, so there could potentially be a good novel use for a 3d printed device. Can you say if you're approaching this from a research/university or from a commercial product design standpoint? I'd be interested to hear what you end up coming up with. Good luck.

      Hey Matt. Thanks for your answer! It didn't come off negative at all. Currently, I am looking into several different medical devices some of which only have surface contact and others of which would require implantation. I am currently conducting research for a research institution. Really, I am just looking at the possibility of 3D printing in the context of medical devices and whether or not it would be beneficial to use 3D printing. The reason why I am looking into 3D printing rather than conventional manufacturing procedures is because the research that I am doing is related to deep space exploration, so standard manufacturing methods aren't really an option when you need to manufacture items on a spacecraft.

        As far as I know in the field of 3d printing nylon filament possess biocompatibility and used in medicine

          My company produces the world's only biodegradable ABS filament. It is called Enviro.

            Wow! A biodegradable filament!
            this is a fantastic innovation, i wonder how long until it becomes cost effective to manufacture all disposable utensils and containers out of such a material!
