Sheet Lamination Printing Service

3Diligent's sheet lamination 3D printing service (LOM, SDL, Ultrasonic Welding) provides customers a cost-effective path to full-color 3D mockups, especially for less complex geometries.

Process Overview

Sheet Lamination is the process of building up a part using sheets of material, commonly paper or metal foil. In this process, sheets of material are bound together to build up the part. For paper, this binding is achieved with adhesive or laminate, whereas ultrasonic waves are used with metal to cause the sheets of foil to vibrate and mesh. In both versions of the process, the outline of the part is cut into the sheet with a laser or a blade, a process that can take place after each layer or a number of layers. This process is ideal for full-color prints of visual mockups that are not terribly complex, have internal structures, or expected to undergo very much stress. Additionally, the process is useful for metal printing processes where the thermal stress of melting metal powder would be problematic.

Sheet Lamination Process at a Glance

Branded Processes Also Known As
Laminated Object Manufacturing (LOM)

Ultrasonic Additive Manufacturing (UAM)
  • Standard Tolerance
    .004" (.100 mm)
  • Stock Surface Finish
    350 – 850 µin Ra
  • Lead Time
    3 – 10 Business Days
  • Maximum Size
    12"×10"×10" (300mm × 250mm × 250mm)
  • Minimum Layer Thickness
    .002" (50 microns)
  • Minimum Feature Size
    0.008" (0.200mm)
Advantages
Full-Color Prints. LOM/SDL can print in the whole color spectrum.
Relatively Affordable. Get your high-quality parts without breaking your budget.
Solid-Body Models. Stock material comes in sheets, which means hollowing the body is not necessary.
No Material State Change. With regards to metal LOM, the process doesn't require melting, which can provide some advantages for applications where melting would pose an issue.
Limitations
Low durability. To successfully be jetted from an ink head, fairly low viscosity—and thus typically less durable—materials are also required. Further, as a general rule, photopolymers weaken over time, especially when exposed to light.
Downward-facing surfaces. Support structures required, the removal of which can impact surface finish and post-processing.
