Portable Laser Marking Machine
The Pryor Portable Laser is a Class 1 certified laser marking machine designed to go wherever the work is. Fully battery powered and requiring no pneumatic air supply, it is the world’s first portable laser marker to combine this level of safety with complete independence from external infrastructure.
- Fully Portable Class 1 Laser.

The Pryor Portable Laser is built around a straightforward principle: the machine should come to the component, not the other way around. When parts are large, heavy, fixed in place, or spread across multiple locations, a fixed workstation becomes the bottleneck and an extra work centre in a manufacturing process. The new Portable Laser removes this.
What makes this machine genuinely different is not just that it is portable. Many machines claim to be portable. The Pryor Portable Laser is the world’s first battery-powered, Class 1 safe portable laser marking machine that requires no external air supply or mains power connection to operate. Competing portable laser systems, require either a mains power connection, a compressed air line, or both. The Pryor Portable Laser requires neither. It runs on battery for a full working day, and where a mains socket is available, it can be plugged in simultaneously, charging the battery while marking continues.
This matters because the practical limitations of portable laser marking have always been the same: where do you get the power from, and where does the air supply come from to allow adequate safety interlocks?

Key Portable Laser Information
At the heart of the system is a 30W pulsed fibre laser source, delivering fast, high-contrast permanent marks on steel, stainless steel, aluminium, titanium, and a wide range of engineering alloys. Two lens options are available: a 70 x 70mm marking field and a 100 x 100mm marking field, giving operators flexibility in marking area depending on the application. Marks produced include serial numbers, part numbers, alphanumeric characters, Data Matrix codes, QR codes, logos, and barcodes.
Class 1 laser safety is standard, not an option. The system uses a vacuum interlock mechanism that physically confirms a secure seal between the marking head and the workpiece surface before the laser can operate. A second layer of safety that works in conjunction with the vacuum interlock is present with four mechanical interlocks. This dual approach ensures that the marking can only proceed if it is safe to do so. This means the Portable Laser can be used safely in busy, open environments alongside other workers, without protective eyewear or additional guarding.
A key part of the safety system is the range of interchangeable masks that allow the marking head to dock securely onto different component geometries. Masks are available for flat surfaces, curved and round surfaces, the end face of bars and tube, and specialist configurations with integrated docking locations and clamps for repeatable positioning. The correct mask ensures reliable vacuum seal confirmation on each marking cycle, regardless of the part geometry.
The Portable Laser is supplied with MarkMaster 4.0, Pryor’s new industrial traceability and laser control software. MarkMaster 4.0 handles layout creation, data entry, serialisation, and integration with production data systems. For operators who need a fully self-contained deployment, the Portable Laser is available with an optional laptop, giving a complete, ready-to-use marking system that requires nothing else to get started.
In addition to the software, a 3” integrated display screen built into the marking head to provide the operator with feedback on marking progress and whether the laser is ready and safe to mark.
Total system weight is approximately 50kg, and mounted on four large wheels designed for use in industrial environments, making the Portable Laser easy to move and deploy by a single operator across a facility or between sites.
Ideal applications include: large fabrications and structural assemblies, castings that cannot be moved, pipework and pressure vessels, vehicles and rolling stock, site equipment and assets, and any marking task where taking the component to a workstation is not practical.
Vacuum Interlock System – Class 1 Safety, Portable Format
The vacuum interlock is the mechanism through which Class 1 safety is maintained in a handheld, portable format. When the marking head is placed against the workpiece, the system creates a sealed chamber and checks that the vacuum condition is met before enabling the laser.
This serves two purposes. First, it prevents accidental activation: the laser cannot fire unless the head is correctly seated against a surface. Second, it ensures consistent mark positioning and quality across every cycle, because the marking head must be properly located before marking begins.
Combined with the interchangeable mask system, the vacuum interlock provides reliable, repeatable performance across a wide range of component geometries.

Handheld Laser Marking Overview
Class 1 Laser Safety
The Portable Laser is a Class 1 laser system. This is the highest level of laser safety classification, meaning the machine is safe for use in open industrial environments without the need for protective eyewear or additional screening for surrounding personnel.
Class 1 safety is achieved through the combination of Pryor’s enclosed marking head design, the vacuum interlock system and the mechanical interlocks. The combined interlocks confirms a secure, sealed contact between the marking head and the workpiece surface before every marking cycle. The laser cannot be activated unless this condition is satisfied. There is no manual override. The system cannot fire in open air.
This level of safety, combined with the machine’s battery-powered operation and freedom from ancillary equipment, makes the Portable Laser suitable for use in working environments where other portable laser options would either present a safety risk or simply be impractical to deploy.
Integrated Display Screen
The marking head features a built-in 3″ display screen, putting key information directly at the point of marking. Before each cycle, operators can use the live outline preview to align the mark accurately on the workpiece, removing guesswork and reducing the risk of misplaced marks. The screen also shows vacuum interlock status, confirming the head is correctly sealed before marking begins, along with system indicators and programme data so the operator can verify the correct job is loaded and ready to run. Having all of this information on the marking head itself means there is no need to refer back to a separate controller or laptop during the marking process, which is a practical advantage when working on large components or in awkward positions.
Interchangeable Mask System
The interchangeable mask system allows the marking head to dock securely onto components of different shapes and sizes. Each mask is designed to create a reliable vacuum seal on a specific surface geometry, ensuring that Class 1 safety is maintained regardless of the part being marked.
Available masks include:
- Flat surface mask — for plates, panels, flat faces, and machined surfaces
- Curved surface mask — for cylindrical, round, or contoured surfaces such as pipes, vessels, and castings
- End of bar mask — for marking onto the end face of round bar, square bar, or tube
- Docking mask with clamps — for applications requiring repeatable positioning, with integrated clamping to locate the head accurately on a specific feature of the component
The ability to switch masks quickly in the field means the Portable Laser adapts to different marking tasks without additional setup time.
MarkMaster 4.0 Software
The Portable Laser is powered by MarkMaster 4.0, Pryor’s new industrial laser marking and traceability software. Designed for real-world production environments, MarkMaster 4.0 provides layout creation, data entry and management, serialisation, and integration with external data systems.
The software has been developed alongside the Portable Laser to ensure a straightforward user experience in field and workshop conditions alike, with clear workflows and minimal setup time for each marking task.
Optional Laptop: Ready to Deploy
For operators who need a fully self-contained marking system, the Portable Laser is available with an optional laptop pre-loaded with MarkMaster 4.0. Combined with the battery-powered operation and the interchangeable mask set, this makes the Portable Laser a complete, ready-to-deploy marking solution that requires nothing beyond the supplied system to begin work.
