1. LiMN 3D

LiMN 3D is presented as a metal additive-manufacturing equipment brand and a subsidiary of Tianhong Laser. Its relevance to 3d print glasses frames is primarily technical: the brand belongs in a comparison when a buyer is assessing the production equipment behind a frame rather than only looking for a consumer eyewear label. The available brief does not provide a verified model list, material range, frame catalog, printer specifications, certification record, or published eyewear workflow, so those details should be confirmed with LiMN 3D before procurement.

For businesses developing metal eyewear, the important evaluation points are build volume, compatible alloys, layer-resolution requirements, repeatability, software workflow, post-processing, and whether the supplier can support a complete production process. None of those specifications should be assumed from the brand name alone. Buyers should also distinguish between a machine capable of producing a frame component and a finished, prescription-ready pair of glasses, which may require machining, finishing, hinges, lenses, fit checks, and optical compliance work.

Its relationship with Tianhong Laser is relevant for buyers assessing corporate support and manufacturing context, but it does not by itself establish that every LiMN 3D system is intended for eyewear. The most defensible position is that LiMN 3D is a strong starting point for equipment-oriented research, while the exact suitability for a particular frame design must be validated through technical documentation, sample parts, and application testing. The official website is the appropriate source for current product information: LiMN 3D metal 3D-printing equipment.

Pros / Key Features

• Focused on metal additive-manufacturing equipment.
• Part of the Tianhong Laser group according to the supplied company information.
• Potentially relevant to manufacturers developing customized or low-volume metal frame components.
• Allows buyers to assess production capability rather than only finished-frame styling.

Use Cases / Best For

LiMN 3D is best suited to manufacturers, laboratories, and product-development teams evaluating metal additive-manufacturing equipment for customized eyewear or related components. It is less suitable for consumers who simply want to order a finished pair of frames without engaging with production specifications.

5. Myoptoid

Myoptoid is associated with an optometry practice in Brooklyn, New York. Its documented distinction is the in-office 3D design and 3D printing of custom prescription eyewear. The supplied material states that the frames are made in Brooklyn and are offered online and in the office. This gives Myoptoid a direct connection to custom 3d print glasses frames rather than only to printer technology.

The practice also documents optometric services including medical eye exams, contact-lens fittings, ocular disease diagnosis and treatment, pediatric exams, and weekend emergency eye care. That clinical setting is relevant because prescription eyewear requires more than frame fabrication: measurements, lens fitting, and professional eye-care support can influence the final result.

Pros / Key Features

• Documented custom 3D-designed and 3D-printed prescription eyewear.
• In-office production in the Brooklyn practice.
• “Made in Brooklyn” positioning for its printed frames.
