The Appearance Model:
An Essential Tool in the Development
of New Automotive Designs
In the automotive sector, manufacturers and suppliers rely on scale prototyping services to validate the design of new vehicles. The appearance model, whether full or partial, interior or exterior, plays a crucial role throughout the design cycle.
This non-functional physical representation allows testing of shapes, curves, colors, materials, and ergonomics of a concept. It helps gather feedback, identify potential issues, and refine design details.
Primarily used internally during the design phase, the appearance model aids in decision-making and optimizes the product development process.

Large-Scale Appearance Model: Support in Design and Engineering
MMB VOLUM-e designs, models, and prototypes your innovative design projects. Our designers create innovative shapes for your future vehicles , in alignment with the latest trends and your brand’s image, optimizing ergonomics and equipment customization.
Our engineering team transforms your sketches into 3D files, while our engineers and technicians ensure the feasibility and design of the prototype.
With an extensive machine park, we create large-scale prototypes (vehicle exterior models, 5-axis machining: 4500x1800x1400mm) and reduced scale models, maintaining a high level of detail thanks to our expertise in additive manufacturing: polymer and metal.
Appearance Model: High-Finish Design
MMB VOLUM-e creates prototypes according to the maturity level of your project, from white models to high-finish models, all the way to prototype in the final material.
With more than 50 years of experience in producing models for the luxury sector, our team possesses exceptional expertise in high-finish prototypes. Thanks to our experts in modeling, painting, colorimetry, metallization, and chroming, we deliver precise and meticulous results at every stage.
Our mastery of additive manufacturing (polymer and metal) allows us to create complex shapes for automotive design, with key advantages:
