How 3D Printing is Reshaping the Tooling Sector
Coming up with a product does not usually entail processing its parts then simply assembling them. A lot of extra tasks come into play during the manufacturing process. A few of them include thinking about logistics and coming up with the packing. One other crucial and unforeseen aspect is developing the tooling. Tooling basically refers to the parts that are key to the proper creation of the final product. This includes creating them in the needed volume along with the prescribed features. The tooling sector often costs investors around the globe billions of dollars. It sometimes accounts for about 50% of the final product cost. Luckily, the recent advances in tech are lowering the price and time of tooling. At Creatingway, we practice 3D printing that is proving to be a promising technique.
As the years pass by, we continue to witness the evolution of 3D printing. A few advances include its improved accuracy, surface finish, and part strength. In addition, its material range for additive production is quickly growing. Around 5 years ago, we were only able to print parts that end up as mock-ups. Today, we have 3D printed parts that end up being vital in automobiles and aircraft. This thus means 3D printing is gaining a foothold as a tooling process. It may soon be possible to replace all conventional tooling methods with it.
Main Factors Between 3D Printing and Soft Tooling Process

Plastic 3D Printing to Replace Soft Tooling
Soft tooling refers to elements that do not need a lot of disabilities. One of the most common examples of soft tooling is silicone rubber molds. It often finds a key role in casting plastic. We often create them from an array of cured silicone mixtures. Meanwhile, we create hard tooling for injection molding from metal alloys. Though they are less durable than hard tooling, they are way cheaper. Silicone molds find an ideal role in small volume production, prototyping jobs, and customizing parts. We only need a master model along with one or two dies to create a batch of parts.

Growths by the Additive Manufacturing Tooling
First and foremost, 3D printing plays a key part in silicone casting. It is critical to the master model creation. 3D printing is awesome for creating single custom parts. Moreover, it does not matter the level of complexity the part holds on the time and final cost. The definition of the master model for plastic casting is a single custom complex part. After completing the master-part, we simply immerse it in liquid silicone. Once it hardens, we end up obtaining two halve of the die.
At Creatingway, our experts happen to go beyond creating the silicon die itself. We sometimes print the silicone molds. This removes the need for post-processing as well as the master part. However, modern 3D printers, do not attain the level of surface finish the client needs. Luckily, it can produce very smooth parts using softer polymers. It is also likely that 3D printers may soon reach the same accuracy with complex material in the near future. If that happens, the usual silicone tooling sector will be an equal alternative.

3D Printing and the Injection Molding Sector
This piece will cover how 3D printing is reshaping the hard tooling sector. Most of this industry entails steel durable dies for use in rapid plastic injection molding of parts. Hard tooling often includes machining fixtures, metal forging dies, and measuring clamp tools. In addition, it may include special measuring tools for specific parts.

Hard Tooling for an Array of Sectors
At Creatingway, we commonly produce hard tooling by CNC machining. We make the fixtures and dies from hard metal alloys or stainless steel. Sometimes, we hard treat them to improve their shelf life. Such materials are tasking to process. For this reason, it costs next to a fortune to produce hard tooling. This is without even mentioning the product’s lead time. Most manufactures produce hard tooling as a single unit or in very small batches. This is owing to its complex geometry with intricate features. This scenario is where 3D printing excels at. It is, however, not common practice to produce dies via 3D printing.

Is 3D Printing the Future of Tooling?
By now, we are aware of the current factors limiting 3D printing in metal. We can thus look further ahead to a time when we have overcome these limitations. By coming up with printers that create precise parts, the pace of manufacturing will skyrocket. We may be able to create dies in a matter of days at a fraction of the initial cost. The profit our client is likely to make from a part will thus be much higher. The material’s hardness will not matter as we can locally melt it and not cut it. Finally, additive manufacturing will allow us to add inner cooling channels. Since bores and drills cannot reach deep spaces and cavities, it results in different cooling rates. A more complex form of channels may make the cooling process more efficient. If you have any inquiries regarding 3D printing, simply contact us.
