Sheet Lamination Services On-Demand

Sheet Lamination Additive Manufacturing

3Diligent’s sheet lamination services is and additive manufacturing process. In this, a 3D object is built by stacking and laminating thin sheets of material, layer by layer. Lamination is achieved using bonding, ultrasonic welding, or brazing and the finished party is completed using laser cutting or CNC machining.

Parts produced using the sheet lamination process are of the lowest resolution in the 3D printing realm, but low cost and short manufacturing runways mean product designers can get low-fidelity prototypes using readily available inexpensive materials.

Types of Sheet Lamination

  • Laminated Object Manufacturing (LOM)
  • Selective Lamination Composite Object Manufacturing (SLCOM)
  • Plastic Sheet Lamination (PSL)
  • Computer-Aided Manufacturing of Laminated Engineering Materials (CAM-LEM)
  • Selective Deposition Lamination (SDL)
  • Composite Based Additive Manufacturing (CBAM)
  • Ultrasonic Additive Manufacturing (UAM)

Each type of sheet lamination process is unique, though the underlying principle is the common factor that relates the processes.

How Sheet Lamination Works

In the sheet lamination process, a thin sheet of material is first fed from the roller or placed onto build platform. Depending on the type of sheet lamination, the next layer may or may not be bonded to the previous sheet. SDL and UAM bond the layers together and then cut the 3D shape at the end, while CAM-LEM cuts the layers into shape and then bonds the layers together. This process is continued until it completes all the layers to achieve the full height. Then the print block is removed, and all the unwanted outer edges are removed to reveal the printed 3D object.

In sheet lamination, layer thickness is same as the thickness of thin sheets of material and dictates the final quality. Layer thickness also depends on the machine and process used.Sheet lamination processes are grouped based upon the build material used or the forming method used (CNC milling, laser cutting, or water jetting). The lamination technique can be used for sub-classifications as well and these include adhesive bonding, thermal bonding, or ultrasonic welding.

 

Further, variations in when they are formed can be used to group the processes, and these include Computer-Aided Manufacturing of Laminated Engineering Materials (CAM-LEM) or Ultrasonic Additive Manufacturing (UAM) process.

In the form-then-bond process, sheet material is first cut using one of the processes listed above and then bonded to either the base—in the case of the first layer—or previous layer. This is repeated until the three-dimensional part is completed.

Conversely, in the bond-then-form process, the layers are bonded together and then cut to produce the three-dimensional part.
