Prototype-making: Things to Consider
“Prototype-making is called the mother of invention.”
It is a multi-step process involving several techniques and many unpredictable elements. However, each step can bring new challenges or solve problems depending on how engineers manage the variables. You must understand the following factors to make the most of rapid prototyping.
#1. Materials Used
Some raw materials can cost more than others, and sheet metal isn’t always an inexpensive alternative. Alloys and synthetic textiles also require fabrication to meet engineering needs. Other pricing and availability factors include sourcing, import and export costs, shipping fees, and facility storage dues.
TIP: Start the prototype-making process with economical options and work up to high-quality materials.
#2. Design Complexity
Detailed product plans can be a higher price tag than straightforward designs. They often require additional machining and fabrication processes to complete. Many also need fine-tuning to ensure elemental compatibility and compliance with industry ISO expectations.
TIP: Begin the prototype-making process with superficial details and move to the complexities later.
#3. Industry Standards
Industry standards for manufactured products vary widely, but nobody can lawfully distribute items not certified by ISO governing bodies. This can change your production plans by requiring additional processing, testing, and certification. Use prototype-making to eliminate errors, compare concepts, and gain approval before producing an entire lineup.
TIP: Work with an ISO-certified manufacturer and seek clarity about industrial regulations.
#4. Prototype Purpose
The primary purpose of your prototype matters, and it’s not all about the costs or lead times. Mindful manufacturing means developing practical products, not just innovative concepts. Prototype-making should help teams align both paths for the most advantageous outcome. However, the details could alter expectations or require additional steps for completion.
TIP: Determine whether you need a scale more for demonstration or a miniature representation.

“Rapid prototyping allows teams to build before building.”
Let’s explore the process step-by-step next.
How to Make a Scale Model with Rapid Prototyping
Many engineering fields build scale models before mass production as part of their standard manufacturing approach. For example, aerospace engineers use prototype-making to check flight characteristics before fabricating airplane wings. Architects assess building site aesthetics and functionality, and energy researchers predict the environmental impact of power plants before construction.
Scale model prototyping help teams determine valuable information about their designs. The data is only obtained through direct interaction with the product, hence the life-sized elements required. Some groups must also examine and test products in the system environment to catch errors and calculate reactions.
Many manufacturing facilities with prototype-making capabilities develop a site plan as the first step. This helps them determine what investors, stakeholders, and consumers think about their products and ideas. Since blueprints are challenging to decipher, scale model representations help demonstrate what cannot be seen on paper. Prototype-making also uses fewer resources than the existing system and can withstand substantial alterations without additional costs or extended lead times.
Types of Scale Models
Teams can manufacture scale models with prototype-making for multiple reasons. There are few rules when developing concepts and fabricating innovations for testing. However, most engineers use rapid prototyping for these three scale model types:
- Performance Models demonstrate how a specific design performs in isolation and within a system.
- User Interface Models highlight various elements’ practicality, safety, and marketability.
- Functional Models compute data without altering the final algorithm, command, or display.

Prototype-Making Step-By-Step
Prototype-making for professionals consists of at least five steps. Many of the steps are non-negotiable, meaning you cannot skip them to save time or money. However, each phase is also imperative to the final result. Developing a scale model without obeying the necessary protocols can be a tremendous waste.
Each project can differ based on many things, but the standard operating procedure for RP is as follows:
Step One: Conduct Research on Industry Expectations and Competitors
You should begin by doing some market research on your industry. Determine the consumer base and discover what they’re looking for. Then check out any investors you want to capture. This will help you determine which prototype-making processes to use and avoid. It can help reveal which innovations are working or failing.
Step Two: Create an Initial Design Blueprint
The preliminary design outlines the elements that make your product unique or marketable. It demonstrates to engineers what your concept should look like, how it should operate, and where it fits into the compatible systems. Hence, step three involves making design blueprints for the team. Many experts use tailored strategies to develop blueprints easily transformed into digital models.
Step Three: Develop the First Virtual Model with Advanced Software
Use advanced manufacturing software to develop a three-dimensional virtual model of your design. This involves help from rapid prototyping experts and experienced engineers. They can help you determine which details will benefit your bottom line while eliminating issues before production.

Step Four: Begin the Prototype-Making Process
Engineers will plug your design blueprints into a sophisticated computer program for processing. This portion of prototype-making is the shortest but most essential. CAD software can render specific elements on-screen for quick adjustments. Then the team can manufacture parts or the whole product depending on their objectives. Rapid prototyping allows for more intuitive product development and produces much less waste.
Step Five: Test the Scale Model for Efficacy and Affordability
The final step in prototype-making is the testing phase. This is where engineers examine the features and evaluate their efficacies. Meanwhile, there are many more product testing benefits, such as determining the affordability of different elements, ensuring ISO compliance, and aligning the various aspects with consumer demands.
Following all five prototype-making steps can be challenging, but a reputable manufacturer can help streamline the process. Rapid prototyping is also a costly service with high upfront fees. The price deters some teams from initiating the RP process. However, multiple money-saving strategies are available to maintain a tight budget.
