FDM technology is the most effective technology for cost effective personalized products.

Thanks, Arafath Mohiv, for your comment. Do you know about the medical grade, soft, and, most importantly, stretchable 3D printing material?

For soft and flexible, we are using TPU filament. But for medical use you need PEEK filament. The PEEK needs higher temperature.

FDM would probably be the cheapest option. That being said if you are coming at it from a quality standpoint, You wont get better quality than resin printing. These machines do take more clean up but as something to go directly into the hands of a customer I think it would be a better bet for flexibles. Additionally, flexibles can be a bit easier and more reliable to print with resin printing machines. I'd look into DLP and SLA machines as well as FDM machines.

On the software side this is getting easier and easier. If you are using meshmixer or something like Prusa slicer (which you may need depending on your printer anyways)

Thanks Aaron Troutman. The resin printing looks suitable. Unfortunately, it takes longer with a higher possibility of reprinting due to the machine performance we got in the lab. Thank you so much for your help, including introducing the two software.

Absolutley! Shohin Aheleroff

I get it, FDM is a much better machine for cranking out parts. Its absolutely doable! If you need anything you know where to find me. Happy Printing

For daily use and tinkering FDM printers are the most suitable and cost-effective, but as your need becomes bigger you will need to offer a special type of FDM printer

Thanks, Mustafa taha Khudhair, for your comment. As you mentioned, FDM is handy. However, it does have some limitations, mainly for printing soft and skin-friendly products.

Welcome, sure it had limitation

so for soft materials or rubbery like tpu and so on

I highly recommend to get a printer with direct drive extruder
