Potomac Photonics delivers advanced microfabrication services for customers requiring micron-scale precision, complex geometries, and tight tolerance control. Leveraging industry-leading laser micromachining, precision CNC capabilities, and hybrid manufacturing workflows, we support product development from early-stage prototyping through low- and high-volume production.
Our microfabrication expertise enables the manufacture of intricate components and devices for medical, microelectronics, photonics, aerospace, and life sciences applications, where accuracy, repeatability, and material integrity are critical.
What Is Microfabrication?
Microfabrication refers to the production of parts and features at the micrometer scale, typically involving feature sizes below 1 mm and tolerances measured in microns. These processes are essential when conventional machining methods lack the precision, surface quality, or material compatibility required.
Potomac Photonics specializes in non-contact and precision-driven microfabrication technologies that minimize mechanical stress, reduce thermal distortion, and enable highly repeatable results across a wide range of materials.
Potomac Photonics Microfabrication Capabilities
Our comprehensive service portfolio allows customers to consolidate multiple micro-scale processes under one roof, reducing lead times, cost, and technical risk.
Micro-usinage laser
Our laser micromachining services enable precise material removal with micron-level feature resolution. Using advanced laser sources and optimized process parameters, we machine delicate geometries without tool wear or mechanical loading.
Découpe laser
Laser cutting provides clean, narrow kerf widths and minimal heat-affected zones. This process is ideal for producing intricate 2D profiles in thin metals, polymers, and specialty substrates.
Laser Micro-Hole Drilling
Potomac offers laser micro-hole drilling for high-density, high-aspect-ratio hole patterns. This capability is frequently used in filtration, fluid control, sensor components, and medical devices.
Structuration laser
Our laser patterning services enable controlled surface modification and microstructuring to impart functional or optical properties. Applications include electronics, photonics, and microfluidic devices.
Marquage au laser
Laser marking provides permanent, high-contrast identification for traceability, branding, and regulatory compliance. Marking can be applied at micro-scale resolutions without compromising part integrity.
Embossage à chaud
Potomac provides hot embossing for replicating micro-scale features in polymer substrates. This process is commonly used for optical components and microfluidic structures requiring repeatable replication.
Micro-impression 3D
Micro 3D printing supports rapid iteration and design validation by producing complex micro-scale geometries, including internal channels and lattice structures. This capability accelerates development cycles and design optimization.
Laser Micro Welding
Laser micro welding allows precise joining of miniature components with minimal thermal input. This process supports hermetic sealing, structural joining, and multi-material assemblies.
Fabrication microfluidique
Our microfluidic fabrication services support the development of lab-on-chip and fluid control devices. Capabilities include channel definition, layer alignment, bonding, and functional assembly.
Bonding and Assembly of Miniature Parts
We offer precision bonding and assembly services for miniature components, ensuring accurate alignment and functional integration across multi-part micro devices.
CNC Micro Machining
By combining the repeatability of Computer Numerical Control automation with the exacting demands of micro-scale fabrication, this technology enables the production of features that are simply not achievable through conventional machining methods.
