Medical & Aerospace Components: Creating precision parts with complex geometries
What is the smallest aperture achievable by chemical etching?
Standard photochemical milling (PCM) achieves 25-50 μm apertures reliably on 0.10-0.20 mm sheet. With optimized process, fine-grain photoresist, and collimated UV, 10-15 μm apertures are achievable on thin nickel or stainless sheet (<0.10 mm). Below 10 μm, electroforming becomes the preferred method.
What tolerance can chemical etching achieve for filter mesh?
Standard tolerance: ±10% of nominal aperture, or ±5 μm (whichever is larger). For example, a 100 μm aperture has ±10 μm tolerance; a 50 μm aperture has ±5 μm tolerance. With tight process control, ±2 μm is achievable on thin sheet for critical applications.
Stainless steel vs copper vs nickel for filter mesh — which to choose?
Stainless steel (304/316L) is the most common — corrosion-resistant, durable, food-grade compatible. Copper is cheaper and easier to etch but oxidizes. Nickel is the premium choice for alkaline battery separators and hydrogen applications — expensive but stable at high temperature. Choose based on fluid compatibility, temperature, and cost.
What thickness of stainless steel for filter mesh?
Typical 0.10-0.50 mm. For aperture <50 μm, use 0.05-0.15 mm sheet. For 100-300 μm apertures, 0.20-0.40 mm. For coarse screens (>500 μm), 0.50-1.0 mm. Sheet thickness must be selected based on mechanical strength requirement of the application.
What is the difference between etching and electroforming for filter mesh?
Etching removes material from a solid sheet; electroforming builds up metal on a mandrel. Etching is faster, cheaper, and works on thicker sheets. Electroforming produces smoother walls and tighter tolerance on very fine apertures (5-25 μm). Choose etching for 25+ μm apertures and high-volume production; choose electroforming for ultra-fine mesh and small batches.
Can chemical etching produce 3D filter structures?
No. Chemical etching is 2D only — it produces through-holes or recesses. For 3D filter structures (graduated porosity, depth-graded mesh), use laser drilling followed by etching, or sintered mesh. For depth-graded mesh, multiple exposures with different photoresist thicknesses can create stepped etch depths.
How much does a precision filter mesh etching line cost?
Lab-scale: GE-FET500 from $5,000 USD. Small-batch: GE-S650 from $5,500 USD. Production: GE-SK9 wide-format from $9,800 USD (supports 650-2500 mm width). Complete photochemical milling line with artwork generation, exposure, etching, and inspection: $25,000-$80,000 USD.
