IDEAS INTO REALITY
Walltosh is a design partner for turning ideas into reality through design and making.
With over 20 years of experience in automotive and mobility design, we support projects from concept and advanced design to product development and 3D modeling.
Walltosh starts with conversation.
What should we create?
Why should we create it?
What kind of value should it bring?
We think, plan and design together.
Walltosh develops ideas with our clients,
turning imagination into something real.
We are a design and development partner
from concept to realization.
SERVICE
From market research and analysis to concept development, design, 3D modeling and prototyping, we support the entire process to turn ideas into meaningful products.
We work alongside our clients from the earliest stages of R&D and product development.

01
Market Research & Analysis
We explore market trends, exhibitions, changing lifestyles and user needs to identify new opportunities for products and services.

02
Product Planning
We identify changes in society and the market, anticipate future lifestyles and user needs, and develop new ideas for products and services.

03
Product Design
We develop ideas into tangible forms by considering function, usability, aesthetics and feasibility. From initial sketches to design development, we create solutions that enhance both product appeal and value.

04
3D Modeling
We translate design ideas into 3D data, refining form, proportion and structure. From design development to prototyping, we create 3D models that help move ideas toward realization.

05
Prototyping
We create prototypes using 3D printing and other methods to evaluate form, usability and overall design quality. From small design studies to larger mockups, we use physical models to refine ideas before final development.

06
3D Printed Products
We design, develop and sell original products created through 3D printing. By turning ideas into real products and bringing them directly to market, we apply what we learn to future product development and design work.
