The MPX-90M impact printer marks two-dimensional DataMatrix barcodes as small as 1 mm on a wide variety of medical instruments such as forceps, tweezers, scalpels and other surgical tools. This proven technology imprints unique device identification (UDI) numbers quickly and affordably, allowing for easy tracking and traceability and resulting in better patient safety. In addition to 2D DataMatrix barcodes, the MPX-90M is capable of imprinting numbers, text, logos and graphics on virtually any metal surface.*1 Designed for ease of use, it comes with its own software for producing precise, durable imprints that remain readable throughout the product lifecycle.*2

  1. *1 Vickers hardness (HV) of the surface of imprintable materials must be 200 or less.
  2. *2 Computer and barcode scanner required for a complete UDI system.


The MPX-90M uses a durable diamond-tipped stylus to directly imprint on titanium, stainless steel and other hard metals. Engineered for speed and precision, the MPX-90M can quickly imprint 26 digits of information inside an area as small as one square millimeter.* Because it does not burn or remove material on impact, the MPX-90M generates no odors or debris, and leaves the marked area protected from corrosion. No daily maintenance is required.

* Quality is determined by the resolution of the barcode scanner.

With the MPX-90M, no special training is required. The included METAZAStudio software instantly converts your numerical data to 2D DataMatrix barcodes that meet GS1 and other 2D DataMatrix formats. Getting started is as simple as firmly securing the item to be marked in the included vise, and then using the built-in laser pointer to locate the center of the material to ensure the graphic is imprinted accurately. With its ease of use, compact footprint and energy-efficient design, the MPX-90M is the ideal solution for small office settings.

METAZAStudio includes a 2D DataMatrix barcode feature. To create a unique barcode, simply select the barcode icon from the METAZAStudio's main screen and enter the appropriate UDI numbers. The software does the rest, creating a 2D DataMatrix barcode that can be output using the MPX-90M. METAZAStudio also imports CSV spreadsheet files for variable data printing. This allows you to quickly and easily add a unique 2D DataMatrix barcode to each device in a series. Support for jpg, bmp and Adobe Illustrator 8 file formats allow you to import logos and other custom branding elements as well.

Conditions when imprinting curved surfaces

Choose material when imprinting on a curved surface taking into consideration the following limitations. These figures show the possible imprinting area on a curved surface that the MPX-90M can imprint with the stylus and the diameter of the cylinder when the head cap (CAP-HEAD MPX-90) is attached to the head unit. However, these limitations do not assure the quality of the photographic image.

Diameter of cylindrical material Recommended printable area (A) Area reached by the marking pins (B)
10 mm (0.3 in.) 2.0 mm (0.079 in.) 2.8 mm (0.11 in.)
20 mm (0.7 in.) 2.8 mm (0.11 in.) 4.0 mm (0.16 in.)
30 mm (1.1 in.) 3.4 mm (0.14 in.) 4.8 mm (0.19 in.)
