A: The L3 Prime can mark text, logos, photos, and patterns on metal surfaces. It can also perform deep engraving and cut thin metal sheets into various shapes. It is suitable for a wide range of jewelry and metal products, including rings, pendants, bracelets, and nameplates.
A: The L3 Prime can mark a wide range of metals, including gold, silver, platinum, brass, copper, stainless steel, and aluminum. Precious metals such as gold and silver can also be deeply engraved and cut from thin sheets. The processing range and results may vary depending on the material composition, thickness, surface condition, and laser power, so a test on the actual material is recommended.
A: The L3 Prime features a 13MP high-resolution camera, a new irregular ring scanning function, automatic angle adjustment for inner-ring marking, and an improved rotary system. Its enhanced air assist and exhaust structure also remove heat and dust generated during cutting more effectively, enabling more stable metal cutting and consistent results compared with the previous L3. These improvements significantly increase convenience and productivity not only for marking and ring engraving, but also for deep engraving and metal cutting.
A: The L3 Prime is available in 60W and 100W models. Both models use a MOPA fiber laser source that allows precise adjustment of pulse width and frequency. They can be used for surface marking on various metals, inner- and outer-ring marking, deep engraving, and cutting.
A: The main difference is the processing speed for deep engraving and cutting. Both models provide similar quality for general surface marking, but the 100W model can reduce processing time for repeated cutting and deep engraving over larger areas.
A: The 60W model is suitable if your main applications are general marking on rings, pendants, and nameplates, with occasional metal cutting. The 100W model is recommended when cutting and deep engraving account for a larger share of your work or when higher productivity is important.
A: Entry-level diode lasers can mark the surfaces of some metals, but they generally offer lower clarity and precision than fiber lasers and have limitations in deep engraving and metal cutting. Low-cost fiber lasers can process metals, but the L3 Prime combines a high-power MOPA laser with a jewelry-specific rotary system, a high-resolution camera, and dedicated software. This allows one machine to handle precise surface marking, ring engraving, deep engraving, and metal cutting.
Even when fiber lasers have the same rated power, actual marking and cutting quality may vary depending on the laser source, optical system, scan head, and control software. The L3 Prime integrates a MOPA fiber laser, precision optics, a 13MP camera, air assist, and dedicated software to provide stable performance across jewelry production applications ranging from fine marking to deep engraving and metal cutting.
A: Yes. Photos, handwriting, fingerprints, logos, and various other images can be imported and marked. Clear, high-contrast source images generally produce better results.
A: Yes. By precisely adjusting the MOPA laser's pulse width, power, speed, and frequency, the L3 Prime can produce clear black marking as well as various colors on certain metals, including stainless steel. The achievable colors and their intensity may vary depending on the alloy composition and surface condition, so a test is recommended when a specific result is required.
A: Yes. Metal surfaces can be deeply engraved by repeatedly processing the same path. This can be used for recessed logos, patterns, seals, and jewelry decoration.
A: Surface marking creates text and images by changing the color or texture of the metal surface while removing little or no material. Deep engraving repeatedly applies the laser to physically remove metal and create measurable depth, so it requires more processing time than surface marking.
A: The engraving depth can be increased gradually through repeated processing, so there is no single fixed maximum depth. The actual depth depends on the type of metal, engraving area, design detail, laser settings, and processing time. If a specific depth is required, a test using the actual material is recommended.
A: With the standard lens, the maximum marking area is 110 × 110 mm. The actual usable area may vary depending on the shape of the item and the clamp being used.
A: Under suitable material and processing conditions, the L3 Prime can clearly mark small text measuring approximately 1 mm or less. Actual readability may vary depending on the font weight, material, surface condition, and marking color.
A: Laser marking generally operates faster than CNC engraving or diamond scribing because it uses a high-speed scan head. Names, dates, and simple logos can usually be marked within a short time. Actual processing time varies depending on the design size, filled area, material, and required quality. Photo marking and deep engraving require more time.
A: Laser marking is a non-contact process that uses a laser beam to process the metal surface. It can reproduce fine text, complex logos, photos, and patterns with clarity and precision. Depending on the settings, it can also produce black and color marking as well as deep engraving.
Diamond scribing uses a diamond tool that applies pressure to engrave lines into the metal surface. The engraved lines reflect light, creating a delicate and premium finish with a distinctive shine. Laser marking is well suited to varied designs and clear visual expression, while diamond scribing is particularly effective for line-based engraving with the characteristic brilliance associated with jewelry.
A: Yes. MagicEngrave-Laser 2 allows you to save and reuse designs and processing conditions for different materials. A dedicated vise or jig makes it easier to maintain a consistent marking position after replacing each item and helps achieve consistent results in repeat production.
A: Yes. Its high-power MOPA fiber laser can cut jewelry metal sheets such as gold, silver, and brass into letters, logos, patterns, and other shapes. The air assist and improved exhaust structure help reduce heat and dust during cutting, supporting stable operation. Both the 60W and 100W models can perform cutting, while the 100W model is better suited to repeat production and shorter processing times.
A: Various metal sheets, including gold, silver, and brass, have been tested at thicknesses of up to 3 mm. However, processing time increases significantly as the material becomes thicker. Considering both processing time and finishing quality, a thickness of 2 mm or less is recommended for general production. Actual cutting performance may vary depending on the purity and alloy composition of the material.
A: Approximate processing times for letters or simple designs measuring 13 × 5 mm are shown below.
| Material and Thickness | L3 Prime 60W | L3 Prime 100W |
| Gold/Silver, 0.5 mm | Within 1 minute | Within 1 minute |
| Gold/Silver, 1 mm | Approx. 2–4 min | Approx. 1–2 min |
| Gold/Silver, 2 mm | Approx. 7–12 min | Approx. 4–7 min |
| Brass, 1 mm | Approx. 4–8 min | Approx. 2–4 min |
| Brass, 2 mm | Approx. 25–50 min | Approx. 15–40 min |
These times may vary depending on the material composition and design.
More complex designs may require additional processing time.
A: Even at the same thickness, gold and silver may require different cutting times because they have different reflectivity and thermal conductivity. Silver may generally require slightly more time than gold, but stable cutting results can be achieved by applying processing conditions suited to the material.
Actual cutting speed and results may vary depending on the purity, alloy composition, thickness, surface condition, and machine specifications. First apply the recommended speed, power, pulse, and number of passes for the material thickness and alloy type, and then fine-tune the conditions through a test cut for more consistent results.
A: Brass generally requires more cutting time than gold or silver of the same thickness. Because it can be more sensitive to heat at high power, the material is often processed in multiple passes with adjusted power settings to reduce deformation and discoloration.
A: Yes. Designs with many small curves and fine details, or with a longer total cutting path, require more time than simple outlines. Actual processing time varies depending on the size and complexity of the design.
A: Higher power is advantageous for reducing cutting time and increasing productivity. However, the final quality is also affected by the speed, frequency, number of passes, and focus setting. Cutting quality does not improve in direct proportion to laser power alone.
A: Yes. Heat-related deformation and discoloration can be reduced by setting the power, frequency, number of passes, and focus appropriately for the material. The L3 Prime's air assist and improved internal airflow also remove heat and dust from the processing area quickly, helping to maintain stable cutting performance.
A: The L3 Prime's air assist and improved exhaust structure help reduce discoloration and residue generated during cutting. Depending on the material and processing conditions, however, the cut edge may retain some roughness, heat discoloration, or resolidified metal residue. In such cases, additional finishing such as grinding or polishing may be required.
A: Yes. The 13MP high-resolution camera allows you to view the material and design positions on the screen. You can adjust the size and position of the design while viewing the actual item.
A: The camera allows you to position a design while checking the item's actual location and orientation, reducing setup time. It is also useful when working with irregularly shaped items or adding new marking to an existing product.
A: Yes. Multiple items can be placed within the working area, with the design positioned separately for each one. For repeat production of identical products, a dedicated jig can also be used for batch processing.
A: The camera calibration function can be used to align the screen position with the actual marking position. Each machine is carefully calibrated before shipment, but an additional check may be required after moving the machine or depending on the installation environment.
A: Yes. Autofocus can be used as an assistive function to quickly estimate the material height and focal position. Because the measurement may vary depending on the material's reflectivity, color, curvature, and surface condition, we recommend confirming the final focal position with the laser pointer for precision marking or cutting rather than relying only on the autofocus result.
A: Yes. The dedicated L3 Prime rotary clamp can mark names, dates, logos, and patterns on both the inner and outer surfaces of rings. Select the inner- or outer-ring marking mode according to the required marking direction.
A: The wireless docking design allows the rotary clamp to be installed and removed easily without connecting a separate cable. The machine detects when the rotary clamp is installed and switches between flat and rotary marking modes, reducing setup time.
A: Yes. The rotary system rotates the ring during operation, allowing text and patterns to be marked continuously around its circumference. The design is arranged according to the size and circumference of the ring before marking.
A: Yes. The irregular ring scanning function rotates the ring and detects changes in its left and right contours, including variations in width and zigzag or wave-shaped edges. It then displays an unwrapped view of the ring on the screen. The user can review the scan and adjust the design's size and position to match the actual ring shape. This function recognizes changes in the ring's width and contours to assist with design placement. It operates differently from 3D scanning, which measures variations in surface height.
A: No. Based on the size of the ring to be engraved, the dedicated auto-tilting rotary clamp automatically adjusts to an appropriate angle for inner-ring marking. This eliminates the need for the operator to calculate and repeatedly set the angle for each ring.
A: Yes. The dedicated bangle clamp can be used to mark text and patterns on the inside and outside of circular or oval bangles. Select an appropriate holding method according to the size and shape of the item.
A: The L3 Prime can be used for pendants, medals, necklaces, bracelets, earrings, watch components, metal nameplates, and many other products. A suitable vise or dedicated jig can be used to hold each product securely according to its shape and size.
A: Available options include a rotary clamp for inner- and outer-ring marking, a bangle clamp, a self-centering vise, a vise for flat materials, and various product-holding jigs. Select the appropriate accessory according to the size and shape of the item.
A: It is used to hold various flat items, such as pendants, medals, and nameplates, easily and securely at the center of the machine. Because the vise grips both sides of the item simultaneously, it is easier to maintain the center position when changing to products of different sizes.
A: Products vary in size, thickness, and shape. Using the appropriate clamp reduces movement during operation and maintains a stable marking position. It also helps maintain consistent positioning and quality in repeat production.
A: The L3 Prime uses MagicEngrave-Laser 2, which is optimized for jewelry marking and cutting. Design editing, text entry, camera positioning, laser parameter settings, and machine control can all be managed within one program.

A: Yes. Power, speed, frequency, pulse width, and number of passes can be saved and reused for materials such as gold, silver, brass, and stainless steel. This reduces setup time and helps maintain consistent results in repeat production.
A: Yes. Designs, layout information, and laser processing conditions can be saved as files and reused for identical or similar work. This makes it convenient to manage repeat production and frequently used personalization designs.
A: Yes. The L3 Prime supports AC 100–240V, 50/60Hz, so it can be used in both 110V and 220V environments. A power plug that complies with local standards must be used, and the machine must be properly grounded.
A: Yes. Marking, deep engraving, and cutting can generate smoke, odor, and fine dust, so a dust collector or external exhaust system must be used. In stores and offices in particular, it is important to provide an extraction method suitable for the materials and expected workload.
A: Yes. A dust collector from another brand can be connected if its duct size and capacity are suitable. The airflow and filter configuration should be selected according to the main materials being processed and the expected workload.
A: Yes. The dust collector can be configured to turn on and off automatically when a job starts and ends. Automatic control availability may vary depending on the specifications and connection method of the dust collector.
A: The exhaust duct connection has a diameter of 75 mm. It can be connected to a dust collector or an external exhaust hose according to the installation environment.
A: Yes. The L3 Prime is a Class 1 enclosed laser product designed to prevent direct laser exposure outside the machine. During normal operation with the safety cover closed, the enclosure and protective window block external laser exposure.
A: Yes. The protective window blocks the laser wavelength, allowing the operator to monitor the work without opening the safety cover.
A: When the machine is operated normally with the safety cover closed, separate laser safety glasses are not required because the protective window serves the same safety function. However, they may still be worn based on the operator's preference or the safety requirements of the workplace.
A: The safety cover opens and closes automatically according to the start and end of each job. This improves convenience during repeat production by reducing the need for the operator to open and close the cover manually.
A: The safety interlock detects the cover status and stops laser operation. The safety sensor must never be disabled or bypassed.
A: The laser and scan head themselves do not generate significant operating noise. However, the dust collector, cooling fan, and air assist may produce a steady level of noise while operating. The cooling system operates according to the machine's condition, helping to reduce unnecessary fan noise.
