Metal mesh for inkjet printers

Metal mesh in inkjet printers – Precise control of liquids and gases

Metal mesh performs critical functions in inkjet printers, controlling, filtering, and stabilizing liquid and gas flows. It operates in confined spaces, with precisely defined flow characteristics, high chemical resistance, and mechanical stability.

In high-performance printing systems – from office equipment to industrial digital printing machines – they ensure precise ink supply, air compensation, and protection of the sensitive nozzle structure.

Application profile: Mesh for fluidics in print heads

In inkjet printers, liquid media, air chambers, and micro print heads are integrated into highly complex structures. Metal mesh provides the following functions here:

Pressure equalization between the ink container, line, and nozzle plate
Ventilation of systems without liquid leakage
Particle filtration to prevent nozzle failure
Flow stabilization in ink lines
Protection against mechanical damage

Thanks to their high dimensional accuracy, extremely fine pore sizes, and dimensionally stable geometry, GKD meshes can be integrated directly into complex microfluidic systems—often in the µl range and at pressures of up to several bar.

Technical requirements and characteristics

Ink and air delivery systems in printers place high demands on the materials used. Metal mesh must be media-resistant, fine-pored, structurally precise, and permanently deformation-resistant.

Technical parameters

Parameter	Typical range
Pore size	6 µm – 300 µm
Wire diameter	12 µm – 460 µm
Materials	Stainless steel 1.4301, 1.4404; Special alloys
Porosity	20 % – 60 % (application-dependent)
Media compatibility	Ink, glycol, water, solvent
Condition	Cleaned, heat treated, and finally inspected by camera in a clean room
Processing	Laser cutting, punching, edge sealing

Meshes with defined pores and tight tolerances ensure reproducible printhead performance throughout their entire service life.

Typical applications in the printing system

Print head protection
- Protection of the nozzle plate against particles and air pockets
- Integration into the rear of the nozzle or as an upstream filter
- Fine-pored fabric with high flow rate at low pressure difference
Ventilation and pressure equalization
- Installation in tank caps or return lines
- Gas-permeable but liquid-tight – for vertical or inclined installation
- Alternatively as a pressure-regulating medium in closed systems
Ink feed and filter mesh
- Pre-filter in ink chambers or cartridges
- Retention function against fiber, dust, or pigment particles
- Optionally as single fabric or multi-layer compact structure
Large format and industrial printing
- Mechanically stable fabrics for protection during high-volume transport
- Thermally resistant fabrics in sublimation or UV systems
- Integration into cleaning and rinsing systems of the printer station

Materials and variants

Material	Properties	Areas of application
Stainless steel 1.4301	good chemical resistance, standard	Cartridges, filters, ventilation
Stainless steel 1.4404	Increased corrosion resistance (e.g., for inks containing acids)	industrial systems, flushing units
Special alloys	for highly aggressive media or cleanroom technology	Special applications, food printing

Available designs: Single mesh, multi-layer mesh packages, laminate mesh, stamped parts with ground edges, formed 3D components.

Processing and integration
GKD supplies mesh as:

Round or rectangular stamped parts with tight tolerances
Cassettes or support frames for direct mounting
Laser-machined individual parts for microfluidic modules
Composite components with carrier, seal, or plastic element

Integration is possible by clamping, overmolding, press-fitting, or friction or laser welding—depending on the housing concept and system requirements.

Advantages of metal mesh in ink printing:

Precise and reproducible flow characteristics
High temperature and chemical resistance
No outgassing or swelling in the medium
Dimensionally stable and vibration-resistant
Cleanable/rinseable
Can be combined with other functions (shielding, protection, cooling)
