Several 3D printing technologies can be used for eyeglasses making, but the most commonly employed ones include:
Selective Laser Sintering (SLS)
SLS is a popular choice for manufacturing eyeglass frames. It works by using a laser to sinter (fuse together) powdered thermoplastic materials, such as nylon, into the desired shape. SLS is known for its high precision and the ability to produce complex and durable structures.
Stereolithography (SLA):
SLA uses a liquid resin that is cured layer by layer using a UV laser or light source. This technology can produce high-resolution and smooth-surfaced parts, making it a good choice for creating detailed and aesthetically appealing eyeglass frames.
Selective Laser Melting (SLM)
The SLM process offers several advantages for titanium eyeglass frame manufacturing, including the ability to create lightweight yet strong frames with intricate designs and high precision. Additionally, because it is an additive manufacturing process, SLM minimizes material waste, making it a more sustainable choice compared to traditional subtractive manufacturing methods.
Multi Jet Fusion (MJF)
MJF is another powder-based 3D printing technology that uses a fusing agent and a detailing agent to selectively fuse powdered
materials. It's known for producing strong and precise parts, making it suitable for eyeglass frame production.

Recommend MJF Printing Technology to Make Eyeglasses Frames, Introducing The Advantages of MJF 3D Printing Process
While there are many benefits to MJF printing, a few truly stand out. For starters, the standard build parameters are optimized for the best density. The result is that Multi Jet Fusion parts are watertight.
If you like SLS but want to produce higher quantities for small-batch production runs, Multi Jet Fusion is the way to go. MJF printers have the ability to print multiple parts simultaneously across the entire build volume means you can print parts at rates up to 10X faster than SLS or other 3D printing processes. Also, Multi Jet Fusion delivers more balanced mechanical properties across the X, Y, and Z axes compared to SLS.
If you’re interested in injection molding for your project, it’s always a good idea to get a 3D printed “test” part before making the investment in metal molds. While SLA is a great printing process for extremely detailed and high-resolution prints, the UV cured resins are not as tough as traditional thermoplastics. Prints begin to degrade when exposed to UV light and moisture. Multi Jet Fusion, on the other hand, can produce extremely accurate prints while also maintaining the structural durability of traditional thermoplastics, especially when using glass-filled nylon. This makes it a great process for testing fit and functionality before taking your project to injection molding.
Fohan MJF Printing Service
Multi Jet Fusion MJF known as HP 3D printing, is an industrial 3D printing process that produces functional nylon prototypes and end-use production parts in as fast as 1 day. Multi Jet Fusion uses an inkjet array to selectively apply fusing and detailing agents across a bed of nylon powder, which are then fused by heating elements into a solid layer. After each layer, powder is distributed on top of the bed and the process repeats until the part is complete. This highly efficient method can build functional, geometrically complex parts 80 micron layers at a time - with mechanical properties that rival injection molded parts.

Postprocessing for HP Multi Jet Fusion Technology
Bead Blasting
This process consists of shooting an abrasive media, usually a bead (size and type results in different surface finishes), at high pressure at a printed part with compressed air, knocking loose unfused powder while also smoothing the finish of the part. This can be done manually or automatically, with manual bead blasting relying on a foot pedal-driven system for propelling the beads as opposed to an automated tumbler, turntable or conveyer. Manual may be preferred for fragile parts.
Sanding
Post-processing techniques can range from manual to almost entirely automated. For example, a company may want to smooth their Multi Jet Fusion parts; this could be done with manual sanding, though it would take a long time and be cost-prohibitive. However, it may work for one-off objects or visual prototypes.
Chemical polishing
This process uses a chemical to smooth the surface of printed parts without impacting its mechanical properties, resulting in a controllable level of glossiness from matt to gloss to shiny.
Dying
Dying: In addition, not unlike other processes, MJF parts can be subject to any number of finishes. Though there is an MJF line dedicated to full-color 3D printing (HP Jet Fusion 580/380 series), these systems are currently designed for smaller batches. When coloring parts that haven’t been printed on those machines, dying can be performed,
either manually in pots of hot water or using automated dying equipment. Dyeing is the most common secondary post-processing technique of MJF users and may be best for parts that are visible or subject to wear, as the color penetrates the surface of the part. Dying white parts, rather than grey, offers a greater range of dying options. Manual dying, which usually involves leaving the part in an 80-100°C dye bath for about eight minutes, is comparatively inexpensive. Automated dying machines, however, may be more efficient, as they use specific programs for mixing the dye bath, as well as conditioning, dyeing, part rinsing, dye disposal, and cleaning.
Painting and Electroplating
Painting and plating are other options for coating Multi Jet Fusion parts. Performing surface smoothing first will help achieve the best results with the least additional effort. Because every industry has its own painting specifications, the best bet is to have samples done with existing painting suppliers. Hydrographs are another method of coating. An image or pattern is floated on water, the part is dipped in it to transfer the pattern over.
Given that a layer of material is applied in the process, hydrographs also result in a smoother surface.Electroplating consists of dissolving a metal in a solution and attaching the metal particles to the surface of the printed part using an electric current. Before this process can be performed on a polyamide part, the part must be made electrically conductive through the use of electroless plating, gas activation, or a conductive coating.
