From broken original to fitment-checked part

MMG combines reverse engineering, CAD design, additive manufacturing, and fitment review to reproduce hard-to-find automotive parts.

Five steps from broken original to delivered part.

  1. 01

    Scan / measure

    MMG starts from a known-good part, broken original, reference photos, or customer measurements.

  2. 02

    CAD design

    The part is recreated or improved digitally, with attention to mounting points, geometry, clearances, and failure modes.

  3. 03

    Additive manufacturing

    Parts are produced using engineering-grade materials selected for fit, strength, surface finish, and application.

  4. 04

    Fitment review

    Critical dimensions, mounting points, and use-case requirements are checked before shipment.

  5. 05

    Worldwide shipping

    Finished parts are packed and shipped from the UAE to enthusiasts and workshops globally.

Engineering-grade material families.

MMG selects materials per part, not per project. The right choice depends on geometry, use case, heat exposure, and fitment requirements.

Nylon PA12

MAT · PA12
Use case
General-purpose trim, bezels, and switch surrounds.
Strength & finish
Tough, stable, low-warp. Good surface finish; paintable with proper prep.
  • Interior
  • Trim
  • Brackets

Carbon-filled nylon

MAT · PA-CF
Use case
Load-bearing or thin-wall parts that need stiffness.
Strength & finish
Higher rigidity and dimensional stability than PA12. Matte technical finish.
  • Interior
  • Mounts
  • Structural trim

Resin (SLA / DLP)

MAT · RES
Use case
Fine-detail bezels, optical housings, master patterns.
Strength & finish
High resolution and smooth surface. UV and heat exposure should be reviewed per use case.
  • Trim
  • Prototype
  • Detail parts

PETG / ABS

MAT · PETG·ABS
Use case
Cost-effective covers, housings, and prototype iterations.
Strength & finish
Reliable, machinable, easy to revise. Used where engineering nylons are not required.
  • Prototype
  • Covers
  • Interior

Metal-print

MAT · MJF·DMLS
Future · Advanced
Use case
Brackets and mechanical parts where polymers are insufficient.
Strength & finish
Evaluated case-by-case. Lead times and cost are significantly higher than polymer parts.
  • Brackets
  • Mechanical
  • Future

Disclaimer · Final material selection depends on part geometry, use case, heat exposure, and fitment requirements. MMG may recommend a different material than initially requested if engineering review suggests so.

Honest about what 3D-printed reproduction can and cannot do.

MMG focuses on parts where additive manufacturing makes economic and engineering sense. We do not over-promise on durability, certification, or guaranteed fitment without review.

  • Fitment-focused design

    Mounting points and geometry are prioritized over cosmetic shortcuts.

  • OEM mounting awareness

    Original fixings, clips, and bosses are retained where practical.

  • Lead time scales with complexity

    Simple trim turns around fast; multi-part assemblies need more iteration.

  • Customer input improves accuracy

    Clear photos and reference dimensions shorten the design loop.

  • Iteration may be required

    Hard-to-find parts can need 1–2 fitment revisions before release.

Have a part that no longer exists?

Send vehicle details, reference photos, and any measurements. MMG will review feasibility and prepare a clear path to a fitment-checked replacement.
