4. Working Principle
Laser Beam Technology
Uses a focused laser to burn
material and create marks
Controller Unit
Manages movement and
power settings
Laser Module
Generates the laser beam
Engraving Surface
Base platform for
material placement
Cooling System Prevents
overheating and maintains
optimal performance

5. WORKING MODEL
MATERIALS & FINDING
Wood: 90x90x5mm | Engraving
Depths:0.2mm,0.4mm, 0.6mm
Ice Cream Sticks: 150x20x2mm | Engraving
Depth: 0.4mm Cardboard: 100x130x2mm |
Engraving Depth: 0.4mm
OBSERVATIONS
Time taken depends on material thickness.
Acrylic requires multiple passes for deeper
engravings.

• EleksMaker is a brand that produces a
variety of tools and devices, including CNC
machines (like the EleksMill and EleksEgg),
laser engravers (like the EleksLaser), and
digital clocks (like the EleksTube).
• These products are often used for creative
and hobbyist applications, allowing users to
engrave, cut, and draw on various materials.

11. FUTURE SCOPE
1. Increase Laser Power – Enable cutting functionality.
2. Expand Application – Support metal engraving.
3. Improve Software Integration – Enhance customization options.
4. Enhance Portability & Durability – Suit industrial applications.
5. Develop AI-Based Automation – Improve precision and efficiency.
6. Integrate Multi-Material Compatibility – Support diverse engraving
surfaces.

12. PROBLEMS SOLVED
1. We made it
compact
2. Portable and easy to
carry
3. Small shop vendors
can buy easily
4. Low maintenance
5. Easy business idea
Maintaining machine during the working
session is essential for projecting proper
engraving with precision. Consider the
following tips for maintaining machine
with perfection:
Choose material wisely
Balanced surface [plane area]
Maintain working area
Eye safety from laser
