3D Design and Product Implementation for Mass Production – What You Need to Know.

Every product – from a simple utility element to a complex industrial device – starts with a 3D model. It is the starting point for prototyping, testing, and ultimately implementation into mass production.

However, simply creating geometry in CAD is just the beginning of the journey. A well-designed 3D model can shorten the implementation process by months, while a poorly prepared one can generate enormous costs and problems during production.

Typical problems with poor 3D design

• Lack of compatibility with the production technology → the element cannot be injected, machined, or cast.

• Lack of material optimization → the product is too heavy, too expensive to produce.

• Poor tolerances and fits → assembly issues, complaints.

• Failure to consider ergonomics or design → product rejected by the user.

What does a well-planned 3D design process look like?

• Requirements analysis

  • Defining the product's functions.

  • Defining constraints (standards, certifications, working environment).

• Matching production technology

  • Elements for 3D printing are designed differently than those for plastic injection, and differently still for aluminum casting.

  • From the CAD stage, wall thicknesses, radii, and undercuts must be taken into account.

• CAD design (3D model)

  • Building geometry with production in mind.

  • Modularity and easy assembly/disassembly.

  • Ergonomics and design tailored to the target group.

• Simulations and optimization

  • FEA → strength and stiffness analysis.

  • Assembly and disassembly analysis.

  • Verification of misuse.

• Prototyping

  • 3D printing as a quick method for verifying shape and ergonomics.

  • Client testing and iterations.

• Preparation for mass production

  • Technical documentation and 2D drawings.

  • Material selection and production processes.

  • Validation and certification.

Project examples

Coffee dripper

Project from concept, through CAD models, to prototypes and preparation for injection molds and aluminum casts. Thanks to analyses and tests, the client introduces the product to stores in several variants.

Children's furniture

From CAD models to FEA analyses in compliance with standards. Final prototypes passed tests without damage – full compliance with simulations.

Automotive (plastics) Switches and interior elements of cars designed from CAD to mass production, with analysis of assembly, disassembly, and misuse. This allowed for reduced complaint costs and improved product quality. 

Industrial tanks and structures

Modeling large tanks in CAD taking into account technological, transport, and assembly requirements. Optimization for strength and costs.

Belt conveyors

3D design of conveyors allows for precise planning of roller arrangements, drives, and belts, as well as checking the ergonomics of the workstation. Modeling can help avoid collisions with other machines in the hall, optimize material flow, and prepare complete documentation for mass production.

Wago-belt packers

In weighing and packing systems, reliability and accuracy are key. The 3D model allows for early checking of component operation, matching elements to hygiene standards (e.g., in the food industry), and planning for easy cleaning of the device. Simulations also allow for assessing durability under dynamic loads.

Steering wheel gearbox for boats

In systems transmitting motion, tolerances and durability are crucial. Thanks to CAD, the gearbox can be accurately reproduced, fits checked, and strength analyses conducted. This allows for the elimination of play and increased steering precision. 3D also facilitates the design of an ergonomic housing resistant to water conditions.

Mold for a twin-hull boat made of resin

Designing a negative in 3D is a huge time and material saver. The CAD model allows for precise reproduction of hydrodynamic shapes, planning the laminating process, and avoiding deformation. As a result, the finished hull perfectly meets the design assumptions, and the cost of the mold is significantly lower than with traditional methods.

Wood saws

A 3D project allows for adjusting the geometry of the casing, cutting mechanism, and safety features in accordance with safety standards. Analyses can predict vibrations, noise, and forces acting during operation. Thanks to 3D visualization, it is also easier to present ergonomics and the appearance of the device to the client before the prototype is produced.

In all these examples, 3D models are the key to:

• eliminating errors before production,

• shortening the implementation time,

• optimizing material and production costs,

• easier communication with clients and contractors,

• greater innovation and competitiveness of the product.

Summary

A 3D project is not just a nice geometry in CAD – it is the foundation of the entire implementation process. The quality of the model determines whether the product will enter the market quickly and smoothly, or whether it will require costly corrections.
