Additive manufacturing has accelerated the tooling development cycle. Today, many companies directly print their tools. The tooling industry is the largest horizontal industry and one of the most crucial for industrial manufacturing sectors such as automotive, aerospace, defense, industrial products, or even automotive products—consumer and medical.
Whatever the application, the right and efficient manufacturing tools increase the efficiency and profitability of the business. The machine tool concept covers a wide variety of applications, including devices, jigs, gauges, molds, dies, cutting equipment, and models. The right tooling is the basis for successful manufacturing and directly affects production capacity as well as product life cycle, quality, and costs.
Although CNC machining is the most widely used technique in the manufacture of quality tools and its results are extremely reliable, it could prove to be expensive and time-consuming compared to other methods such as additive manufacturing, including options that could be cheaper and more efficient.

Additive manufacturing at the heart of the development cycle
Additive manufacturing has dramatically decreased the tooling development cycle and is playing an increasing role in major industries. According to a recent survey published by Ernst & Young, a fifth of companies active in the aeronautics, automotive, mechanical, and engineering sectors use this technology to print their tools.
Tooling additive manufacturing applications cover a wide range of uses, including tooling used in casting and machining processes, assembly jigs and fixings, as well as custom medical guides. Materials currently used in tooling manufacture include plastics, rubber, composites, metals, wax, and sand.
Freedom of tooling design and the ability to create more functional end products
When evaluating additive manufacturing’s innovative opportunities, a key strategy isn’t to focus entirely on; however, this technology will revamp existing components or replicate ancient processes’ results.
The main question is how additive techniques are often wont to come through results that are unaffordable or not possible with ablative machining. Freedom of design offers several opportunities. Designers and engineers can benefit from just about endless choices to enhance tool designs. When composed of many parts, the power to consolidate the planning helps to reduce the impact of assembly operations and material costs.
Moreover, the ability to include advanced options permits for quicker production of highly purposeful parts, thereby limiting defects whereas permitting freeform style. In the case of a cooling system design, biotechnology is often enclosed within the design to enhance technician comfort, method cycle time, and easy access and storage of tools.
Shorter manufacturing lead time for tooling
Additive manufacturing for tooling also helps reduce the entire product development cycle. It serves as an engine for innovation. Companies sometimes choose to delay or cancel product design updates due to the need to invest in new tools.
By reducing tooling production time and enabling rapid updates, additive manufacturing allows companies to replace and improve tooling more frequently. Having an in-house additive manufacturing system also shortens the supply chain and reduces (or even negates) the risk of receiving faulty tools.
Additive Manufacturing Cost reduction
While current prices are usually higher in metal additive production compared to ancient metal fabrication, price reductions will be achieved simply with polymers. The selection of materials depends on the utilization of the tools to be manufactured.
Metal additive manufacturing for tooling may but be financially advantageous for little series of finished products, within the case of particular geometries optimized by CAD/CAM, associated, or in cases wherever the manufacturing causes a high rate. Waste of pricey materials.
The ability to make a correct tool inside hours as and once the requirement arises is vital for workflows and can be helpful once the production period or tool inventory is costly.
Finally, this technology’s pliability permits engineers to repeat several take a look at versions, reducing the direct prices caused by tooling style changes.
Rapid tool production Using additive manufacturing
Only when the amount of production is massive can the tooling cost be justified. Therefore, how to produce tools faster and more economically, especially for small-batch manufacturing, has become of great concern. In the process of product design and development, there is always a need for intermediate tools to produce samples for marketing, functional testing, or planning and evaluation of production processes.
In this regard, the rapid production of tools can meet the needs. The result of the combination of rapid prototyping techniques with classical tooling practices allows the production of a small quantity of plastic or metal components from CAD data. Direct Metal Laser Sintering — DMLS), which manufactures production tools from CAD data, is the most common method for duplicating plastic components.
