Identify any additional processing procedures that the prototypes may require. Some rapid prototyping processes may need secondary processes like curing, painting, or polishing to get the preferred results.  Also, it would be best to consider the required time and resources for the post-processing steps.

Rapid Prototyping 

Rapid prototyping is the process of quickly building a 3D object to visually, and functionally, evaluate a design.  There are several popular methods to choose from to rapidly prototype an object including vacuum casting, CNC machining and 3D printing to name a few. There are two categories within rapid prototyping: 

Low-fidelity prototypes: this is when the prototype has noticeable differentiations to the proposed final product.  

High-fidelity prototypes: this is when the prototype matches the proposed final product. 

Applications: 

Rapid prototyping processes are largely used by product designers and engineers. This is because it enables them to physically view how their product will appear or work in the early stages of design.  

Having a physical model is also beneficial for clients who are working with designers, as it allows them to comprehend each aspect of the product in context. As a result, clients are generally able to provide designers with more accurate feedback because they can see and touch it. This gives room for alterations and improvements to be made in the early stages.  

 Jumping the gun straight into mass manufacturing is asking for a headache, especially due to the fact that fixing errors or making alterations at this late stage takes a lot of time and money. Rapid prototyping offers fantastic precision and is used to create accurate model geometries. It is an affordable way to test your product and we encourage everyone to make use of it! 

3D Printing 

3D printing is a type of additive manufacturing process. Additive manufacturing describes the technology that is used to build 3D objects. As its name implies, it involves adding material layer-upon-layer to create an object.  

 By contrast, traditional manufacturing processes are subtractive – such as carving, milling, and machining. In additive manufacturing, computer-aided-design (CAD) directs data to hardware that can physically add material in layers to form precise geometries. 3D printing is one of several types of additive manufacturing processes.  

 Applications: 

It is becoming more prominent for 3D printing to be used in manufacturing as an additive process. There are a growing number of companies employing this on a large scale. You might be wondering – why use 3D printers for this? Well, 3D printers offer the opportunity to create complex parts that would otherwise be too difficult or expensive to manufacture using traditional dies, moulds, milling, or machining. With intricate features and complex part geometries becoming feasible to manufacture, really the sky is the limit for 3D printing.  

Other advantages include a reduction in assembly pieces. In contrast to traditional methods of joining multiple pieces together, you can now 3D print all of your pieces as a single part, which can increase strength and durability. 3D printing can make a part weight lighter and reduce waste drastically. In fact, it can reduce waste by up to 90% compared to using traditional subtractive manufacturing methods.   

 Aerospace Companies 

Key applications include environmental control systems (ECS) ducting, custom cosmetic aircraft interior components, rocket engines components, combustor liners, tooling for composites, oil and fuel tanks and UAV components. 

 Medical Industry 

Key applications include true-to-life anatomical models, orthopaedic implant devices, dental devices, pre-surgery models from CT scans, custom saw and drill guides, enclosures, and specialized instrumentation.
