3D printing is being used more and more in the manufacturing industry, as companies are looking for ways to increase efficiency and reduce costs. However, it is unlikely that 3D printing will completely replace traditional manufacturing in the near future, as there are still certain advantages to traditional manufacturing processes such as cost-effectiveness, high precision and production scalability.
There are also some specific materials that 3D printing cannot currently handle, such as metals or ceramics. Therefore, the two methods of manufacturing should be used together for optimal results. If a project manager or a procurement, in a project, or a product development process, can use the most suitable process at different stages, then will get the lowest cost and maximum benefit results.
This article will further discuss the differences between 3D printing and traditional manufacturing methods, present their advantages and disadvantages.
What is 3d Printing?
3D printing is a process of creating three-dimensional objects from digital designs.
It is also known as additive manufacturing, and involves the layering of specific materials
such as plastics, metals or composites to create an object based on a set of instructions.
The parts created can be extremely precise and complex in shape, making it a popular choice for prototyping and production purposes. Additive manufacturing processes are able to print complex designs at no additional cost.
What Does Traditional Manufacturing Include?
Traditional manufacturing methods typically involves subtractive methods such as CNC machining, die casting, and injection moulding to create an end product from raw materials. It also includes assembly techniques like welding and riveting, as well as injection molding for mass production of objects.
The final product typically requires additional finishing processes such as sanding and polishing to achieve the desired result.
3D Printing Vs Traditional Manufacturing: 10 Key Factors
When evaluating 3D printing against traditional manufacturing, there are several key factors to consider.
Firstly, the cost of the machinery used in 3D printing compared to traditional methods.
Secondly, the types of materials that can be used with each process.
Thirdly, the complexity and size limitations of parts created with each method.
Fourthly, scalability options for both processes in terms of production speed and quantity.
Fifthly, availability and accessibility of materials for each type of manufacturing.
Sixthly, the accuracy of parts produced through each method.
Seventhly, delivery times for completed products from each manufacture method.
Eighthly, how easy it is to modify products using either process.
Ninthly, maintenance and repairs for machinery used for either manufacturing process.
Lastly, environmental benefits or drawbacks associated with selecting one type of manufacturing over another.
1.Precision: 3D printing can produce extremely precise parts with high accuracy and repeatability, while traditional manufacturing technologies are often limited in their ability to achieve the same level of detail. Traditional manufacturing is better at producing functional parts.
2.Speed: 3D printing as a additive manufacturing can create components with complex geometries quickly and easily, while traditional manufacturing processes require more time-consuming tooling. Lead time will be shortened.
3.Variety: 3D printing offers a much wider range of materials than traditional manufacturing, allowing for pieces of all shapes and sizes to be created quickly and efficiently.
4.Cost: 3D printing proves to be more economical for low volume manufacturing/short-run production. due to its faster process time, reduced waste, and low cost material inventory requirements. setup costs are also a factor that has to be considered for a kind of traditional manufacturing technology.
5.Scale: While traditional manufacturing is better suited for large scale production runs, 3D printing, as a additive manufacturing process has the advantage of being able to produce a single part or small batch run with equal efficiency as mass production runs.
6.Complexity: Complex designs are easy to achieve with 3D printing since no tooling is required, while traditional manufacturing requires additional tooling for intricate parts which can add both time and cost to the process.
7.Durability: Traditional manufactured parts have proven longevity when used under normal conditions but may have difficulty withstanding extreme temperatures or stressors that parts printed on a 3D printer often handle just fine.
8.Waste: Since most additive manufacturing do not require cutting or machining tools, It will hardly waste material in comparison with traditional methods which typically generate more scrap material as part of the finished product, increase manufacturing costs Unavoidablly.
9.Efficiency/Versatility: With modern technology it’s possible to combine both additive and subtractive processes into one hybridized workflow that allows for faster creation of complex designs without compromising accuracy or surface finish quality.
10.Eco-Friendliness: As mentioned before the reduction in raw material wastage in 3d printing means fewer resources are needed for producing each component which helps reduce pollution associated with production operations as well as reducing costs associated with disposal of hazardous materials from factories.
Advantages of 3D Printing Compared to Traditional Manufacturing
3D printing offers a number of advantages when compared to traditional manufacturing processes. There are 4 main advantages of 3d printing over traditional manufacturing
Speed
- Faster, more cost-effective, can produce desired object in one go, reduces warehusing and shipping costs.
Cost effectiveness
- Low material waste, only support structures and raft.
Accuracy
- 3d printing can produce more parts with complex shapes and greater accuracy, which gives designers more design freedom.
Customization
- Has the ability to create custom products which can be tailored specifically for a customer’s needs.
Lead time
- Shorter lead times, 3d printing reduce the amount of time needed to go from conception to finished product while lowering overhead costs.
Disadvantages of 3D Printing Compared to Traditional Manufacturing
Costs
- the cost of the machinery used in 3D printing is still relatively expensive when compared to traditional methods, when it comes to mass production.
Materials
- 3D printing is unable to handle all materials, such as certain metals or ceramics, traditional manufacturing has more material options than 3D printing, for example, CNC milling.
Limitations
- 3D printing can be restricted by the shapes and sizes it can produce due to limitations in software and hardware. The size of the printing bed can also limit the production of parts,in cpmparison to the traditional assembly line.
Quantity
- Production scalability remains an issue with 3D printing as it is difficult to produce large quantities quickly, something which can be done more efficiently with traditional manufacturing processes. traditional manufacturing processes are much suitable for mass/large scale production.
Will 3d Printing Replace Traditional Technologies?
No, 3d printing will not replace traditional processes.
3D printing, additive manufacturing, is being used more and more in the manufacturing industry, as companies are looking for ways to increase efficiency and reduce costs.
The process of using specialized equipment to assemble an object layer by layer has some unique and interesting advantages over traditional manufacturing. However, it is unlikely that 3D printing will completely replace traditional methods in the near future, as there are still certain advantages to traditional manufacturing techniques such as cost-effectiveness, high precision and production scalability, even for rapid prototyping.
Why traditional manufacturing has its uniqueness?
There are also some materials that additive manufacturing processes cannot currently handle, such as metals or ceramics. Therefore, the two methods of manufacturing should be used together for optimal results. Traditional manufacturing still has an irreplaceable position.
How to Select a Manufacturing Process for Your Product
By comparing the differences between 3d printing and traditional manufacturing technology, do you know how to choose a suitable process?
Selecting the right manufacturing process for your product can be difficult and requires careful consideration. Businesses are most concerned with lead time and costs incurred.
Firstly, consider the type of product you are creating and what materials it will consist of. Think about how complex its design is and how big the desired production quantity is. Some materials can only be formed by certain manufacturing processes.
Research the different manufacturing processes available to see which one fits your requirements best. If you only need rapid prototyping, or prototypes with small quantities to test market feedback, then CNC is more economical than die casting. In general, the higher the tooling costs, the lower the part cost, and vice versa. CNC milling, no tooling cost, high part cost. Die casting, high tooling cost, low part cost. Look into the availability and cost effectiveness of each process before making a decision. If you need certain surface finishes for your products, like Injection molding allows for in-mold decorating, where as extrusion does not.
Finally, don’t forget that switching from one process to another may require additional set up costs so it could be beneficial in the long run to select a method that can fulfil all your needs from start to finish. Even some traditional manufacturers have added 3D printing as a complement to expand their production capabilities.
