As a dual-light source desktop laser marking machine, the EM-Smart Dual shares similarities with other leading brands yet delivers its unique competitive edge. In this section, we’ll dive deep into comparing its performance, key strengths, and expansion accessories against two flagship models: the LaserPecker 4 (LP4) and LaserPecker 5 (LP5). This comprehensive analysis will empower you to make an informed choice when selecting the ideal desktop laser engraver for your needs.
For most DIY crafters, precision ranks among the top three considerations when purchasing a desktop laser engraver. Applications like custom branding, jewelry engraving, and artistic designs demand exceptionally high-precision laser engraving.
Equipped with a hybrid 20W fiber laser + blue diode laser system, the Dual offers two distinct beam spot sizes:
With a maximum speed of 10,000 mm/s and EM-Smart’s proprietary motion control, this desktop laser engraver delivers industry-leading precision, rapid processing, and unwavering stability – making it an exceptional choice for detail-intensive engraving projects.
As Laserpecker's inaugural dual-laser desktop engraver, the LP4 combines a 10W blue diode laser and 2W infrared laser to significantly broaden material compatibility—engraving everything from wood and acrylic to stainless steel and anodized aluminum.
However, due to the infrared laser's technical constraints, the LP4’s maximum engraving speed at 4,000 mm/s. Notably, it supports color engraving techniques (e.g., anodized aluminum tinting) and achieves 8K resolution for photorealistic results.
The LP5 replaces the infrared laser with a 20W fiber laser while retaining a 20W blue diode laser. This dual-source configuration delivers a remarkable engraving speed of 10,000 mm/s.
One highlight of LaserPecker 4 and LaserPecker 5 is the color engraving functionality via precise energy modulation on metals and coated surfaces.
Deep engraving is mostly applied into materials like wood or slate, while if you would like to try this on metal, you'll choose a desktop laser engraver with enough and stable laser power output. EM-Smart Dual has some deep engraving cases below:
Limited by LaserPecker 4's 10W diode + 2W infrared laser configuration, LP4 lacks dedicated deep engraving specifications in official documentation.
With upgraded 20W fiber + 20W diode lasers, LaserPecker 5 matches EM-Smart Dual in 3D grayscale embossing and depth performance: Generates dimensional artwork on metal, stone, and wood via energy modulation technology.
Manual cutting can be a better choice for nonmetallic materials like paperboard, leather or fabric, etc. But if you prefer precise and smooth cutting edge and patterns, a desktop dual-light source laser engraver will be added into your crafting list.
The biggest profit of EM-Smart Dual is that dual laser source can handle almost all materials including wood, leather, plastic even metal sheet. And there are three elements: material, laser type and parameters. Below is the cutting comparison:
| Material/Machine | EM-Smart Dual | LaserPecker 4 | LaserPecker 5 |
| Wood | 17.88mm | 8mm | 20mm |
| Acrylic | 14.21mm | 5mm | 14.6mm |
| Strainless steel | 0.53mm | / | 1mm |
The size of the working area directly impacts a user's ability to perform batch engraving. While previous EM-Smart series desktop laser engraver focused heavily on diversifying fiber laser functionalities and boosting overall laser performance, continuous improvements have also been made in user adaptability.
However, operating in a bare machine configuration during complex patterns, deep engraving, or cutting applications generates smoke and debris. This poses dual risks: it obscures the operator's view and presents an inhalation hazard. Consequently, nearly every brand's bare unit requires a separate safety enclosure or protective cover.
Addressing these user needs comprehensively, EM-Smart's latest release is Dual, the integrated dual-source desktop laser engraver. This machine comes equipped with a built-in protective enclosure. This integrated design effectively eliminates issues like laser glare and fume inhalation.
Furthermore, the Dual significantly expands the working area to 230*230mm (approx. 9 x 9 inches). This represents roughly 135% of the marking area found on standard desktop laser engravers. EM-Smart Dual accommodates the marking area requirements of the vast majority of users, offering capabilities approaching larger platforms.
The most distinctive feature of LaserPecker brand lies in the compact size, lightweight portability, and handheld capability of its desktop laser engraver. While this offers relative advantages in terms of form factor, the primary drawback of smaller models is the reduced working area. Whether comparing the LaserPecker 4 (LP4) or its upgraded successor the LaserPecker 5 (LP5), both models support a maximum working height of 150mm. However, their maximum working area remains constrained to 120 × 160mm (approx. 4.7 × 6.3 inches).
Although the handheld functionality provides undeniable convenience, it introduces potential safety hazards and challenges in maintaining consistent engraving quality during operation, especially for horizontal projects requiring precision.
Operating software is essential for desktop laser engraver, directly impacting user experience and engraving results.
The EM-Smart series provides free access to professional laser software EzCad and LightBurn, offering advanced control interfaces for precise engraving. Both platforms benefit from large user communities on Facebook and Reddit, where troubleshooting tips and technique sharing are readily available. LightBurn further adapts to diverse skill levels with three interface modes (Beginner, Intermediate, Professional), ensuring accessibility for all users.
LaserPecker relies on its proprietary LaserPecker Design Space (LDS) software, which integrates basic tools like drawing brushes, shapes, image vectorization, and QR/barcode generation. While LDS lowers the design barrier for beginners, it lacks advanced features such as node editing or path optimization. Complex designs require preprocessing in third-party software (e.g., Illustrator). And the bluetooth transmission frequently fails with large files (e.g., high-resolution images). The LP5 can connect to LightBurn but cannot control fiber laser frequency, use rotary accessories, or enable real-time preview. Critical functions like 3D grayscale engraving remain exclusive to LDS.
EM-Smart prioritizes user safety with critical upgrades.
While compact size enhances portability, safety compromises exist:
The three models show limited differentiation in accessory support:
Both EM-Smart Dual and LaserPecker 4/5 requires a 4-in-1 rotary attachment for curved surfaces and a flexible fixture for rotary engraving. LaserPecker 4/5 needs an add-on dust enclosure and external exhaust system to achieve smoke-free operation.
Based on the above comparison, both EM-Smart Dual (prioritizing professional-grade performance) and the compact LaserPecker series (emphasizing portability) offer viable entry points for beginners.
| User Profile | Desktop laser engraver | Key Features |
| Mobile Retailer | LaserPecker 4/5 | Ultra-portability, handheld flexibility for on-site engraving |
| Workshop Owners/Craftsman | EM-Smart Dual | Superior material compatibility, engraving speed, precision, and stability |
The Dual’s integrated design and distinctive color scheme make it a visually striking centerpiece in creative studios or retail environments, while delivering industry-leading engraving experiences.
