The Mastrex MX-300 is a production-grade Laser Powder Bed Fusion (LPBF) metal 3D printer for advanced manufacturing education, applied research, prototyping, and industrial workforce training. Its 11.81 × 11.81 × 13.78-inch build volume and two independent 500 W lasers support larger parts, higher part quantities, and production-oriented projects.

Learners can practice workflows that include large-build preparation, dual-laser operation, powder recovery, depowdering, part removal, post-processing, inspection, and process documentation. Tech-Labs provides the MX-300 as a training solution manufactured by Mastrex.

Large-Build LPBF Platform

Expand project scope with room for larger components, higher part counts, and complex multi-part layouts.

Dual-Laser Throughput

Introduce learners to coordinated multi-laser processing using two independent lasers that cover the full build area.

Production Workflow Learning

Connect build planning, powder handling, post-processing, inspection, and documentation within a production-oriented metal AM workflow.

Scale metal additive manufacturing instruction with a large-build, dual-laser LPBF system.

Hands-On Metal Additive Manufacturing Skills

When supported by the program's curriculum and operating procedures, the MX-300 can help learners develop skills in:

  • Explaining LPBF technology and the role of multi-laser processing
  • Preparing and reviewing large, production-oriented metal additive builds
  • Planning large parts and high-density multi-part layouts
  • Configuring, operating, and monitoring a dual-laser LPBF system
  • Explaining laser coordination, calibration, and overlap considerations
  • Relating layer height, beam diameter, build rate, and scan speed to production goals
  • Planning powder recovery, depowdering, part removal, and heat treatment
  • Inspecting surface finish, dimensional results, and build consistency
  • Documenting process settings, quality checks, and build outcomes
  • Metal additive manufacturing
  • Advanced and industrial manufacturing
  • Manufacturing and mechanical engineering technology
  • Materials science and metallurgy
  • CAD and design for additive manufacturing
  • Aerospace, automotive, energy, and industrial applications
  • Medical-device manufacturing concepts
  • Applied research and process development
  • Large-part and batch-production instruction
  • Workforce upskilling and industrial training

Large Build Volume

An 11.81 × 11.81 × 13.78-inch build volume supports larger components, higher part counts, and complex build layouts.

Dual 500 W Lasers

Two independent lasers cover the full build area, giving instructors a platform for teaching multi-laser operation and production throughput.

Multi-Laser Scan Coordination

Mastrex uses coordinated scanning and calibration to support consistent results across the full build platform.

0.0008–0.0047 in. Layer Range

Instructors can explore how layer thickness affects surface finish, detail, build time, and productivity.

Material Flexibility

Mastrex lists titanium alloy, stainless steel, aluminum, cobalt-chromium alloy, copper alloy, and additional compatible materials.

Integrated Touchscreen Computer

A centralized interface supports machine control, workflow monitoring, instructor demonstrations, and supervised learner operation.

  • Built-in computer with touchscreen
  • Three build plates
  • Tool set
  • Professional on-site installation and training
  • Two-year warranty
  • Lifetime support

Confirm transport, the final configuration, site requirements, electrical service, service scope, and included items with Tech-Labs before installation.

  • Heat-treatment oven: Supports post-build stress relief and application-specific heat-treatment workflows.
  • S400 sieving machine: Supports recovery and reuse of metal powder within an approved material-handling workflow.
  • DPS400 automatic depowdering machine: Uses controlled rotation, vibration, and airflow to remove loose powder from printed parts while reducing manual handling.
  • Powder-collection system: Supports routine printer cleaning with filtration and a stainless-steel collection container.
  • Closed-loop powder-handling system: Connects the printer with sieving and depowdering equipment to support contained powder transfer.

Mastrex identifies professional on-site installation and training as included. Its product page does not identify a packaged academic curriculum, student workbooks, assessments, eLearning library, LMS integration, or credential alignment.

Programs should plan to integrate the MX-300 into their own additive-manufacturing curriculum or confirm additional instructional resources with Tech-Labs during project planning.

The MX-300 combines a large production-oriented build volume with two independent 500 W lasers for advanced training, research, and production development.
