InssTek

Core Technology: DMT and DED

At the heart of InssTek’s operations is its proprietary DMT (Direct Metal Tooling) technology. Unlike traditional additive manufacturing methods that rely on powder bed fusion, InssTek utilizes the DED process. In this process, metal powder is delivered into a laser-focused melt pool, where it is fused onto a substrate layer by layer.

Key technological pillars include:

1. CVM (Clogged Vibration Method) Powder Feeding: This is one of InssTek’s most distinct engineering innovations. The CVM system is designed to provide highly accurate and stable feeding rates with precise micro-volume control. By effectively managing the flow of metallic powders, the system ensures consistent material deposition, which is critical for high-integrity parts. The system supports "Hexa-Feeding," allowing for the simultaneous use of up to six different materials, enabling the creation of functionally graded materials (FGMs) and complex bimetallic structures.

2. AM-CAM Software: To manage the complexity of multi-axis metal printing, InssTek developed its own AM-CAM (Additive Manufacturing Computer-Aided Manufacturing) software. This suite includes features for path optimization, multi-material transition management, and collision avoidance for 5-axis operations. The software allows for precise control over laser parameters and tool movement, ensuring that the additive process can be simulated and executed with high fidelity.

3. Closed-Loop Feedback Control: The company’s systems utilize real-time feedback mechanisms to monitor the melt pool and deposition quality during the printing process. This helps in maintaining structural integrity and surface quality across various geometries.

Product Portfolio

InssTek offers a range of printing systems tailored to specific industrial and research needs, categorized primarily under the MX Series:

MX-Lab: Designed specifically for R&D, metallurgy, and material science, the MX-Lab is a compact, 3-axis system. It is the entry point for organizations looking to conduct alloy development, test new powder combinations, or perform fundamental research on metal matrices and high-entropy alloys (HEAs). It features a built-in CVM powder feeder and is optimized for ease of installation in academic or lab environments.

MX-Fab: The MX-Fab series represents the industrial-grade solution. These machines are typically 5-axis systems, which allow for greater freedom in geometric complexity and the ability to print on angled or non-flat surfaces. The MX-Fab is designed for high-performance component fabrication, localized repair of industrial parts (such as turbine blades and vanes), and the production of large-scale parts that require robust mechanical properties.

MX-Med: Recognizing the unique requirements of the healthcare sector, InssTek developed the MX-Med. This system is specialized for the production and surface treatment of orthopedic implants. It is particularly noted for its ability to apply uniform, porous titanium coatings on implants, which promotes osseointegration (the structural and functional connection between living bone and the surface of a load-bearing artificial implant). This process ensures medical-grade quality for implants that must integrate safely with the human body.

Industrial Applications

InssTek’s technology is deployed across several high-demand sectors:

• Automotive: The company utilizes multi-material printing to fabricate thermally conductive molds and other engine components where different material properties are required in specific zones of the same part.
• Aerospace and Power Generation: The ability to perform DED-based repairs is a critical service. InssTek’s technology allows for the reclamation of expensive, high-value components—such as power plant turbine blades—by adding material to worn or damaged areas, rather than replacing the entire component.
• Metallurgical Research: By enabling the synthesis of new alloys in small quantities (using the 6-hopper feeding system), InssTek supports industries and researchers in developing new metal composites and high-entropy alloys rapidly and cost-effectively.
• Medical Device Manufacturing: Beyond simple implants, the company’s precision deposition is used to create structures that mimic natural bone geometry, enhancing the success rate of orthopedic surgeries.

In summary, InssTek provides an integrated ecosystem—hardware, proprietary powder feeding systems, and CAM software—that enables manufacturers and researchers to move beyond the limitations of standard subtractive manufacturing or single-material additive processes. Through its commitment to DED technology and in-house innovation, the company continues to influence the adoption of metal additive manufacturing in specialized industrial fields.
