Modular Additive Manufacturing system for printing heterogeneous synthetic tissues and sensors

At ALT LLC, we use additive manufacturing for making prototypes, tooling, molds, and various objects with the conventional Fused Filament Fabrication (FFF) approach, the printing of specialty materials such as Ultem with high-end enclosed printers, and DLP resin printers for high resolution. We also have developed many novel printing processes, custom tools, and printheads for printing synthetic tissues and sensors.

If you are interested in high-strength and other specialty materials then

Additive Manufacturing or 3D printing involves the layer-by-layer construction of objects from digital models. This technique has gained significant traction in various industries due to its ability to produce complex geometries that are difficult or impossible to achieve with traditional manufacturing methods. There are also advantages for Sustainability, fast turn-around time, and methods of printing novel materials.

Novel materials play a crucial role in the advancement of additive manufacturing. Researchers at ALT LLC are continually exploring new materials that can enhance the properties of printed objects. These materials include biocompatible polymers, composites incorporating metals or ceramics, and bio-inks for printing synthetic tissues. The development of such materials enables the production of lightweight, durable, and functional components, particularly in the biomedical field.

At ALT LLC we have developed a wide range of synthetic tissues that can be printed and or molded into heterogeneous tissue structures such as the abdominal wall tissue model shown to the left.

As researchers continue to explore the synergy between new materials and advanced processes, the potential applications in fields such as prosthetics, aerospace, and healthcare are expanding rapidly. The ongoing evolution of additive manufacturing promises to not only optimize production techniques but also to pioneer solutions that could enhance performance and functionality in a wide array of industries.

In terms of processes, innovations such as continuous 3D printing, selective laser sintering, and digital light processing are redefining capability and efficiency in additive manufacturing. These methods can reduce production times and improve the accuracy and surface finish of the end products. Furthermore, process control and monitoring technology advancements ensure consistent quality in printed items.
