History of Sheet Lamination Machines

The journey of sheet lamination machines began with the advent of 3D printing technology. This transformative tech, also known as additive manufacturing, emerged in the 1980s.

In 1991, a significant development took place. Dr. Carl Deckard, a researcher at the University of Texas, introduced a patent for a new technique called Selective Laser Sintering (SLS). Although not sheet lamination, this marked a crucial step in the evolution of 3D printing techniques.

Fast forward to 1999. Professor Behrokh Khoshnevis from the University of Southern California patented a method known as Contour Crafting. This process, resembling sheet lamination, involved the layering of material.

The real breakthrough came in the 2000s. The Mcor Technologies company in Ireland invented a unique sheet lamination process. This process employed adhesive to bond layers of paper, creating full-color 3D printed models.

Since then, sheet lamination machines have continually evolved, becoming an integral part of the 3D printing industry. The journey reflects the relentless pursuit of innovation and the commitment to transform ideas into reality.

Evolution of sheet lamination technology in 3D printing

The evolution of sheet lamination technology in 3D printing is a story of constant innovation and refinement.

Initially, the technology was primarily based on paper lamination. This involved bonding layers of paper with adhesive and shaping them with a knife or laser. Mcor Technologies, an Irish company, was a pioneer in this field, with its line of paper-based 3D printers.

As the technology matured, so did the materials used. In the mid-2000s, new methods started to emerge, employing metals and plastics. This opened the doors to a wider range of applications, particularly in industries like automotive and aerospace.

Around the same time, Ultrasonic Additive Manufacturing (UAM) was introduced. This technique uses ultrasonic welding to bond thin metal sheets together layer-by-layer, then a CNC machine removes excess material. UAM brought an unprecedented level of precision and control.

In recent years, the focus has been on improving efficiency and reducing costs. This has led to the development of faster lamination processes and the use of cheaper, more readily available materials.

Overall, the evolution of sheet lamination technology in 3D printing reflects the broader trend in the industry: a relentless push for better, faster, and more cost-effective ways to turn digital designs into tangible objects.

Leading Manufacturers of Sheet Lamination Machines

In the realm of sheet lamination machines, there are a few noteworthy companies actively contributing to the field. The pioneer of this technology was Helisys Inc, which developed the first Rapid Prototyping System (LOM) but unfortunately ceased operations in 2000. Their legacy, however, continues through Cubic Technologies, which now oversees the sales and service support for their products.

Historically, other companies like Solido 3D and Japan-based Kira Corporation exclusively utilized the LOM process, but these companies either shut down in recent years or transitioned to different techniques.

An Irish company, Mcor Technologies LTD, was committed to mainstreaming the LOM process until its closure in 2019. Mcor offered professional 3D printers that used LOM and worked with standard A4 papers. Various industries, such as architecture, art, development, and medicine, found these machines useful for producing cost-effective models.

Cubic Technologies launched the SD300 3D Printer, a LOM desktop model. The machine fabricates objects from sheet plastic. However, with a hefty $15,000 price, it’s more expensive than similar FDM printers like the MakerBot Replicator or 3D System’s Cube, priced between $1,300 to $2,200.

Cubicure, a Vienna-based company, is another important player in this field. They specialize in the production of high-precision polymer parts using a process they call “Hot Lithography”. This is a photopolymerization-based process that allows for a high degree of precision and surface quality in the final parts.

Finally, there’s Impossible Objects, an American company that has pioneered a new approach to 3D printing called Composite-Based Additive Manufacturing (CBAM). Their process involves using sheets of composites like carbon fiber, which are then selectively printed with a polymer and stacked to create a 3D object. The object is then heated to bond the layers together, creating a strong, lightweight part.

Cubicure

Cubicure is a Vienna-based company that specializes in the field of 3D printing technologies. The company was spun off from the Vienna University of Technology in 2015 and has been innovating in the additive manufacturing industry ever since.

Cubicure’s core technology revolves around the photopolymerization of resins, a process known as Stereolithography (SLA). However, they have made notable advancements in this field with their patented Hot Lithography technology. This unique approach involves heating the resin before curing it, resulting in parts with higher dimensional stability and mechanical properties.

The company offers a variety of 3D printers and a wide range of resins that cater to different applications. Their Caligma 200, for instance, is a high-precision 3D printer designed for industrial use.

While Cubicure does not directly work with sheet lamination techniques, its contributions to the 3D printing industry through resin-based technologies are significant and worth noting.

Impossible Objects

Innovative business Impossible Objects is situated in Northbrook, Illinois, in the United States. The business was established in 2009 with the intention of transforming the additive manufacturing industry.

The company’s proprietary 3D printing method, known as Composite-Based Additive Manufacturing (CBAM), combines the advantages of additive manufacturing with the advantages of composite materials. Parts can be produced using this approach that is both lighter and stronger than those made using conventional manufacturing techniques.

The CBAM process is novel because it actively employs sheets of composite materials like carbon fiber, Kevlar, or fiberglass. These sheets undergo selective printing with a polymer binder to assume the shape of the desired item. The process then stacks, compresses, and heats the layers to fuse them together. After removing the extra material, it produces a highly resilient, lightweight component that various industries can use.

The technology of Impossible Objects has received praise for its originality and potential influence on the industrial sector. The company’s Model One and Model 2 printers can mass-produce high-performance parts and are intended for industrial applications.

Impossible Objects uses a technology that is a form of sheet lamination even if they don’t use the phrase “sheet lamination” to describe their procedure. They stand apart in the 3D printing sector thanks to their distinctive strategy.

Commercially Available Sheet Lamination Machines in the Market

Cubicure’s Hot Lithography systems: These machines use a unique method of stereolithography, which is technically not sheet lamination, but it’s worth mentioning due to Cubicure’s significant contributions to the field of 3D printing. Their Evolution and Evolve machines are known for high precision and versatility, capable of processing a broad range of materials.

Impossible Objects’ Model One and Model Two printers: These use a process called Composite-Based Additive Manufacturing (CBAM), which involves laminating sheets of material together, similar to the process of sheet lamination. They are known for their ability to create parts that are both lightweight and strong, using materials like carbon fiber, fiberglass, and Kevlar.
