China3D printingNet February 2nd, South Korean researchers have used3D printingThe machine has produced cheaper and customizable artificial testicles for patients who need testicular transplantation.
Unlike traditional replicas, the team’s new silicone gonads can perform3D printing, To match the specific patient anatomy, making them more comfortable and lifelike. Essentially, the researcher’s additive oil droplets are designed to meet their Korean demand for low-cost artificial balls and provide wearers with confidence enhancement.

A variety of medical emergencies, from tumors to testicular torsion, can occur in male genitalia, so it must be removed quickly. Although doctors adapt prosthetics to such patients in practice, these men often suffer psychological trauma similar to those experienced by women after mastectomy.
Although the replica does not play a physical role in the human body, its bizarre shape or appearance may particularly damage the male self. According to the South Korean team, inappropriate ready-made implants can have a huge impact and cause “inferiority complex”.
In addition, because many pseudotesticles are of the same size, they may cause discomfort to the patient and even escape in the body, leading to serious complications. The scientists also emphasized the plight of victims from their native South Korea, where the American company AMS reached an exclusive agreement to provide customized products.
Since they sell for about 800,000 won (approximately US$715), the price of many men has exceeded the price of a new testicle, and most insurance companies do not provide surgical services, which further complicates the problem. To this end, the Korean team set out to develop a new type of prosthesis that can be customized according to the needs of each patient while maintaining the safety of external use.
Once the team finished printing the prosthesis, they post-processed and shaped it. The image is provided by the International Journal of Engineering Research and Technology.
3D printingUpgraded implant
Before printing, the scientists mixed silicone resin LSC-40 (a polymer used in handicrafts) with RTV-THINNER to make a fast-hardening flexible rubber. Once the best materials were developed, the team used patient data and Creo Parametric 3D modeling software to develop small, medium and large testicular models.
Later, before post-processing and bonding it with the red putty, use3D printingThe machine divides the shake lock itself into three parts to ensure high accuracy. After processing them, the team then performed a silicone molding process on the balls to give them a smooth, bio-friendly appearance.
During the test, scientists discovered that the “split oil” of silicone is an effective cleaning agent, and its high viscosity means that only one application is required. Moreover, the team concluded that although their balls use glue similar to other prostheses, their customized nature may make them less prone to failure.
3D printingAnd keep breasts
Although use3D printingThe machine-created prosthetic testis does represent a fairly novel use of the technology, but it has been deployed in a similar way before helping female cancer patients.
For example, a team from South Korea’s Asan Medical Center used3D printingThe surgical guidelines can allow cancer patients to retain more breast tissue after surgery. During the test, the scientists found that they can be as close as 1cm from the tumor, so that they can get the best results for the patient.
Similarly, the medical startup myReflection has also developed a combination3D scanningAnd molding methods to manufacture personalized breast prostheses. This new addition device is made of ISO-certified external silicone and has a service life of up to four years, which is longer than traditional implants.
In other respects, in terms of materials, medical scaffolding developer BellaSeno has begun to use RESOMER polymers from the chemical company Evonik for breast reconstruction. With the unique biocompatibility of this plastic, the company’s goal is to make implants that can be safely absorbed by the human body.
