Dynamic Focus Desktop Platform
Mini 3D Laser Marking Machine
A 700 x 500 x 550 mm cabinet that marks curved surfaces properly. The dynamic focus axis moves with the XY galvanometer, so steps, cones, tapers and large curved faces are engraved without the distortion a fixed-focus marker leaves behind.

Format Comparison
Mini 3D vs Standard 3D: Footprint and Reach
The two formats do the same job on different parts. This table is about where the machine has to live and what it can reach from there.
| Property | Mini 3D platform | Conventional 3D platform |
|---|---|---|
| Cabinet size | 700 × 500 × 550 mm, one-piece desktop cabinet | Floor-standing frame with a separate cabinet for the source and controls |
| Machine weight | About 55 kg | Built to stay in one position on the floor |
| Installation | Bench or trolley top, single-phase supply, air-cooled | Fixed foundation, more space around the machine for loading |
| Marking area | 200 × 200 mm maximum | Larger fields for big flat and contoured workpieces |
| Surface handling | Dynamic focus covers steps, cones, tapers and curved sections | Dynamic focus plus a longer Z travel for tall parts |
| Best-fit parts | Small to medium curved and machined components | Large, heavy workpieces that are difficult to lift onto a bench |
The right-hand column describes the general format of a floor-standing 3D marking platform rather than one specific model. Only the left-hand column repeats machine datasheet values. Send us the part and we will say plainly which of the two formats you need.
How It Works
How a 3D Head Marks a Curved Surface
A fixed-focus marker keeps one flat focal plane, which is why a logo stretched over a cylinder goes soft at the edges. A 3D head does not accept that compromise.
- Dynamic focusing axisThe dynamic axis works with the XY galvanometer instead of against it, so focus tracks the surface height as the beam travels.
- Distortion-free markingSteps, cones, inclined faces and large curved objects are marked without the elongation that a flat-field correction cannot solve.
- Deep work in 3DThe same coordinated motion lets the head carry out deep engraving and texture etching on complex relief, not just surface marks.
- Three-dimensional job preparationThe software imports, edits and maps a 3D model so the toolpath already understands the shape before marking starts.
Curved Surface Work
Curved and Stepped Parts Marked in One Setup
Bearings, pistons, gears, tooling inserts and shaped gift items all share the same problem: the surface refuses to be flat.
01
Rotational and Cylindrical Parts
Bearings, pistons and gears are marked with a rotary axis while the dynamic focus keeps the character height constant around the curve.
02
Tapers, Cones and Steps
Multi-level stepped faces and conical sections are marked in a single program, instead of being split into several flat operations.
03
Relief and Texture
Layered relief, deep engraving and surface texture are produced on shaped parts, which is the work a flat-field marker cannot attempt.

The product introduction describes an integrated marker weighing 15.5 kg, while the machine parameters table gives about 55 kg for the KR-3D50-Mini to KR-3D100-Mini range. The technical table values are used on this page. The scanner is also referred to as a 3D FEELTEK F10 in the product description and as 3D Sino-galvo in the parameter table; the parameter table designation is used here and the actual unit is confirmed on the order.
Software and Mechanics
Deep Engraving on Three-Dimensional Geometry
Three elements decide whether a 3D job comes out sharp: the focusing axis, the software that drives it and the bench the part sits on.
Dynamic Focus System
The galvanometer and the dynamic axis are controlled together, which extends marking beyond flat work into curves, inclines, cones and multi-level steps.
Eastern Logic 3D Software
A three-dimensional interface with import, edit and mapping tools. It coordinates the dynamic axis with the XY galvanometer for layered relief and texture etching.
One-Piece Aluminium Workbench
Multiple threaded holes accept a dedicated fixture plate, and the aluminium body gives stability, heat dissipation and a long service life under heavy use.

Operating Routine
From CAD File to Finished Part
A 3D job starts in the model, not at the machine. These four steps keep the setup predictable.
01
Import the Model
Load the 3D model or the surface data into the software and check that the orientation matches the part on the bench.
02
Map the Job
Place the graphic or texture on the mapped surface and set the depth, line spacing and power for the material.
03
Fix the Part
Locate the workpiece on the aluminium bench, using the threaded holes for a fixture plate or the rotary axis for cylindrical parts.
04
Run and Compare
Mark the first part, check depth and edge quality against the approved sample, then lock the job file for production.

FAQ
Mini 3D Laser Marking FAQ
The focusing axis moves in step with the XY galvanometer. Instead of holding one fixed focal plane, the head follows the surface, so steps, cones, inclined faces and curved sections are marked without distortion.
The cabinet measures 700 x 500 x 550 mm and weighs about 55 kg, so it can stand on a bench or a trolley instead of taking a dedicated position on the factory floor.
Brass, carbon steel, mould steel, stainless steel and silicon carbide are all covered. The 1064 nm source gives deep, high-contrast results on metal surfaces and can also mark coated and textured parts.
Eastern System runs the machine and Eastern Logic 3DS handles the dynamic focus control. The 3D interface lets the operator import, edit and map a three-dimensional model, and the software coordinates the dynamic axis with the XY galvanometer for layered relief, deep engraving and texture etching.
For 3D marking applications we recommend 50W or higher. The range covers 50W, 60W, 80W and 100W, and the larger powers give deeper engraving, wider application coverage and reliable long-term performance.
The maximum marking area is 200 x 200 mm, the line width range is 0.01 to 0.1 mm, the minimum character size is 0.15 mm and marking speed runs from 0 to 7,000 mm/s.
No. The machine is air-cooled, which keeps the installation simple. The cabinet is built from sturdy metal sheet so the desktop stays stable during deep engraving operations.
Automotive, aerospace, medical devices, electronics and semiconductors, tool and die making, promotional gifts, watches and accessories, and sculptural or trophy work where curved surfaces and deep engraving are common.
