In the journey of product development, prototyping plays a pivotal role. And a prototyping shop serves as a crucial resource for bringing ideas to life. As an engineer at Yigu Technology, I have had extensive experience collaborating with prototyping shops, and in this article, I'll share insights into what these shops offer, their significance, and how to optimize their use.
The Multifaceted Offerings of a Prototyping Shop
Fabrication and Testing Equipment Galore
Prototyping shops are equipped with a diverse range of fabrication and testing tools. For example, the ME Prototype Shops are a haven for students and researchers. They house various equipment that enables hands - on learning. This practical approach helps translate theoretical classroom concepts into real - world applications. The presence of such equipment is not just beneficial for educational purposes but also for professional product development.
Applied Kinetics' prototype shop is another great example. It has a machine shop with a wide array of capabilities. CNC machining is one of its fortes. With CNC machining, they can produce multiple parts for destructive testing. This is invaluable when you need to understand the limits of your design. For instance, they can produce complex geometries, which is often a challenge in traditional manufacturing methods. The shop can also compare machining speeds and feeds on specific materials to achieve the best surface finish. In fact, their Fraisage CNC has a travel of 20” [510mm] x 14” [355mm] x 18” [460mm] with 4th axis capabilities, and Tournage CNC can handle through the chuck up to Ø2” [Ø51mm], with a maximum Ø8 1/4” [Ø210mm] OD and a machining range of 16 1/2” [420mm].
Manual machining capabilities are also available in these shops. This is useful for quick one - off parts, jig and fixture machining, and modifying purchased components. Such flexibility allows for rapid iterations in the prototyping process.
Professional Staff for Guidance
The staff in prototyping shops are a key asset. Comprising professional engineers, machinists, and technicians, they bring a wealth of knowledge and experience. They not only train users on how to operate the equipment safely and efficiently but also offer consultations on projects. Their expertise can help in avoiding common pitfalls in the prototyping process. For example, when working on a complex mechanical prototype, the staff can provide insights on the best manufacturing techniques based on their past experiences, saving both time and resources.
In - House Testing and Assembly
Prototyping shops offer in - house testing capabilities. Applied Kinetics can conduct first - order compression and tensile testing, friction determination, fatigue/cycle testing and analysis, and functional testing of proof - of - concept parts and assemblies. This comprehensive testing ensures that the prototypes are thoroughly evaluated before moving forward in the development process.
Assembly and disassembly are also important services. The ability to perform component - level and machine - level assembly/disassembly is useful for reverse engineering proven equipment, initial start - up and testing of machines, and ease of assembly of proof - of - concepts. They even have well - documented assembly/disassembly procedures and maintenance and safety manuals, which add to the professionalism and reliability of their services.
3D Printing for Added Flexibility
In - house 3D printing is becoming an increasingly common feature in prototyping shops. For example, some shops can perform FFM printing up to 30cm x 30cm x 30cm. 3D printing allows for the creation of complex geometries with relative ease. It is also a cost - effective option for producing small - scale prototypes, especially when compared to traditional manufacturing methods for low - volume production.
Comparing Prototyping Shops with In - House Prototyping
| Aspect | Prototyping Shop | In - House Prototyping |
| Equipment Diversity | Usually has a wide range of specialized equipment for various prototyping needs | May be limited depending on the company's investment and focus. Smaller companies may not have access to high - end or specialized equipment |
| Staff Expertise | Staff with diverse backgrounds, including engineers, machinists, and technicians, bring broad industry knowledge | In - house teams may have more focused expertise, depending on the company's product line. They may lack exposure to a wide range of industries and techniques |
| Cost for Small - Scale Projects | Can be cost - effective for small - scale projects as the cost is shared among multiple users. Some shops may even offer subsidized rates for academic projects | In - house prototyping can be costly for small - scale projects as the company has to bear the full cost of equipment, maintenance, and staff |
| Time to Market for New Skills | Prototyping shops can quickly adapt to new prototyping techniques and technologies, allowing clients to access the latest methods. This can speed up the development process | In - house teams may take longer to adopt new skills and technologies, especially if there is a lack of investment in training and research |
My Perspective as an Engineer
From my experience, prototyping shops are an essential resource, especially for companies that do not have the resources or expertise to set up an in - house prototyping facility. Their ability to offer a wide range of services under one roof is a huge advantage. The professional staff and diverse equipment allow for a high level of flexibility in the prototyping process. However, communication is key when working with a prototyping shop. It is important to clearly define your requirements, timelines, and budget from the start. Also, while prototyping shops offer great services, it is still important to have a good understanding of the prototyping process on your end. This will help you better collaborate with the shop staff and ensure that the final prototype meets your expectations.
FAQ about Prototyping Shops
1. How do I choose the right prototyping shop for my project?
When choosing a prototyping shop, consider their equipment capabilities. Make sure they have the tools necessary to fabricate the type of prototype you need. For example, if your prototype requires complex CNC machining, ensure the shop has the right CNC machines with sufficient precision and size capacity. Look at their staff expertise. A shop with experienced engineers and technicians is more likely to provide valuable insights and high - quality work. Check their portfolio and customer reviews to gauge their past performance. Also, consider the cost and turnaround time. Get quotes from multiple shops and compare them based on your budget and project timeline.
2. Can a prototyping shop help with both simple and complex prototypes?
Yes, prototyping shops are equipped to handle both simple and complex prototypes. For simple prototypes, they can use their manual machining capabilities or basic 3D printing to quickly create a model. For complex prototypes, they can leverage their advanced CNC machining, in - house testing, and experienced staff. For instance, if you have a complex mechanical design that requires precision machining and thorough testing, the shop's CNC machining and testing capabilities can be used to bring your design to life and ensure its functionality.
3. What if I need to make changes to my prototype after it's completed by the prototyping shop?
Most prototyping shops are flexible and can accommodate changes. However, it's best to communicate any potential changes as early as possible. If the changes are minor, they may be able to make them quickly at a relatively low cost. For more significant changes, they may need to re - evaluate the project scope, cost, and timeline. It's important to work closely with the shop staff to understand the implications of the changes and to ensure that the final prototype still meets your requirements.
