How Rapid prototyping helps you Design and Develop Products quickly

Product design failure in the development stage is a huge loss for the organization in terms of man-hours and the money invested in the development process. A tangible prototype of the product makes the complex product design looks simple. It helps product designer and engineers in visualizing and analyzing the actual part of the product before the development stage. This drastically reduces the chances of product failure to a great extent.

It helps you to develop every component of the complicated product in stages and compare every part of it with the prototype prepared. Any deviation from the prototype can give you a clear indication of the design failure of the part and it helps the development team to rectify the error immediately.

Why Rapid Prototyping?

  1. Clear understanding and visualization of the Design Concepts
    It acts like a POC for the client and it’s easier to understand the design rather than struggling to visualize by looking the design on the screen or paper. It helps the designer to understand the look and feel of the design rather than having a virtual design through CAD model.
  2. Quick changes or modification
    Having a visible and tangible model provides manufacturers with the better understanding of how the product may look like. It helps them analyze the actual design and suggest correction or modifications quickly which can be incorporated to make the product design perfect before advancing to the manufacturing stage.
  3. Reduction in monetary investment and time consumption for Designing
    Rapid prototyping creates a model very similar to what an actual product can look like. This eliminates a need for preparing molds and use of other software to create a model. The existing CAD software and printing equipment are sufficient to create a rapid prototype which gives you a feel of an actual model. This not only result in saving of time and cost invested in creating the actual models but also results in overall reduction of your time to market.
  4. Product Customizations
    Rapid prototyping empowers you in developing the customized products with ease. A small modification in CAD model is sufficient to create a modification in the existing design without the need for any special tool or process.
  5. Higher Accuracy level in designing
    The material used for the prototyping has similar properties of the actual product. This makes it easier to perform the physical tests and identify the flaws and errors prior to the actual manufacturing process. This helps manufacturers to avoid the risk of halting the manufacturing process at a later stage.

Nowadays, manufacturers are more inclined towards rapid prototyping while initiating their new product development and manufacturing process. These revolutionary techniques are making things easier for product development companies, and product manufacturers in developing innovative products cost-effectively.

Key Differences Between Production and Prototype Tooling

In product development, testing is a critical factor. In some cases engineers need to demonstrate how a new design will perform as part of management approval for investment into production. In other cases, regulatory requirements require testing of products from representative materials and processes that correspond to those intended. As part of its prototyping methodology, manufacturers often use different strategies for executing prototypes depending on the purpose of the parts. When injection molding is involved in the final product, the use of specially engineered polymers in the product specification may result in the need to injection mold the parts being used in testing in order to get reliable results. Depending on the circumstances, the final production injection molds may be used or separate prototype tooling may be utilized. The goal is to ensure a superior prototype and timely testing, which helps identify design changes before taking a product into full production.

There are a number of key decisions, which go into the prototype tooling process, which enables a design team to select the appropriate build strategy. A key element to consider is the degree of uncertainty or uniqueness of a particular design. The more unique a given design is from a company’s previous manufacturing experience, the more critical it is to test process and product early. Likewise, overall program schedule plays a big factor. The component in need of testing may just be one part of an overall system being developed. Final production tooling timing may be aligned more with the overall system’s development schedule. If so, waiting for production tooling may be a costly risk delaying valuable testing time. In those cases, a simple prototype tool to allow early evaluation of the component or sub-system may be a great investment. Finally, the likelihood a product may change should also be a factor in considering if separate prototype tooling should be used. If a design change is likely or probable, it is better to identify this early rather than executing the change to final production tooling which could require welding on the tool steel or other changes which might compromise the integrity of the mold for long run use.

For both production and prototyping, every tool is different. Two factors, which strongly influence the distinction between the two, are as follows:

  • Production Quantity – The degree of automation in a tool is often correlated with the production quantity intended. High production molds often are highly automated with wear maintenance provisions, sensing and process control capability built into the design. These factors add to the time and cost of the tooling but provide cost and processing efficiencies in the actual volume molding itself. Likewise high production molds are often multi-cavity allowing several parts of the same design to be molded simultaneously. Prototype molds by contrast, typically have limited automation and cavities, saving time and cost in fabrication and thus are suited to low volume molding with quicker development time.
  • Hard vs. Soft Tooling – Another difference between the prototype tooling process and production tooling process has to do with tooling materials. Production tooling is often made from hardened P20, H13 or other tool steel suitable for repeated use and long tool life. Heat-treating and surface hardening or plating are also often utilized. Prototype tools are often called soft tools based on the fact that aluminum and or mild steel are often used. This tooling material can be cut quicker in the machining process allowing for faster and more cost effective prototype tools. The tradeoff however is that tool life may be limited depending on the plastic intended to be molded and processing is not optimized for shortest cycle time. Soft tooling can offer affordability for both production and prototyping. However, because it allows for quick turnarounds of samples, it is often the preferred choice for prototypes.

Tooling is a big investment and cost is always an important deciding factor. Therefore, a manufacturing company will determine which type of tooling makes the most sense from a financial perspective and any product based factors necessary to make the right choice.

Why Choose CNC Rapid Prototyping

When it comes to rapid prototyping, there are several different options. These include 3-D printing, sand casting, selective laser sintering, investment casting, fabrication, and CNC rapid prototyping. While they all offer unique advantages, there are some unique advantages to CNC prototype machining.

What Is CNC Prototype Machining?

CNC prototyping involves utilization of 3D solid model CAD designs as the input, and correspondingly fabricating the part directly from solid material through a computer controlled cutting and milling process. Some have used the term, “subtractive” rapid prototyping to describe this process, to contrast it with 3D printing, which is sometimes referred to as “additive” manufacturing. The subtractive aspect is that the CNC machine removes material from a starting material block to create the final part precisely to the CAD model specifications. With modern CNC machines, this material removal process is efficient, quick, and accurate to demanding specifications. Because of this subtractive nature, CNC prototyping allows for parts made from literally any material that is machinable and commercially available in cast or extruded stock. This provides material versatility and permits prototyping in materials that are often identical or very similar to those specified in production use. CNC prototyping suppliers offer an outstanding option for low volume customized products and prototypes with precision results!

While prototyping offers many benefits, two stand out. First, by creating a model before producing hundreds or thousands of finished products, engineering teams can identify potential problems, often times minor geometry or functional issues that by human nature are inherently difficult to catch in a computer model alone. This can allow the manufacturer to make the necessary corrections before going into full production, which saves a significant amount of money. Secondly, human factors, or how humans interact with the product are most often best assessed on the prototype. Issues such as color, texture, feel, light, shadows, temperature to touch, resistance to motion, etc. can be assessed with prototypes made to high craftsmanship, quality, and proper materials.

A Broad Reach

Prototyping and CNC Prototyping in particular can benefit any industry, whether aviation, automotive, architecture, aerospace, construction, medical, or something else that requires a finished product with precision and detail. Investing in the prototype process with CNC machining reduces the risk of time-consuming and costly mistakes.

Likewise, CNC is a viable option for many lower volume production projects. Depending on the geometry and material, whether a customer needs 100 or 1,000 units, CNC machining may be an excellent option as it eliminates the need for upfront tooling and molds due to its “on-demand” manufacturing methodology. Whenever a customer needs a plastic or metal prototype or multiple pieces in low volume manufacturing, CNC machining can be an outstanding process.
