End-to-End Technical Product Design & Development

From initial concept to production-ready product.

iterator.de provides end-to-end technical product design and engineering services for businesses looking to develop new products, improve existing designs or turn ideas into manufacturable solutions.

Combining industrial design, mechanical engineering, CAD development, prototyping and practical manufacturing expertise, we support the entire product development process — from initial requirements and feasibility studies through concept development, detailed design, functional prototyping, testing and design for manufacture.

Our approach bridges the gap between creative product design and real-world engineering. We consider functionality, material selection, manufacturing processes, assembly, durability, cost and maintainability from the outset, helping to identify technical challenges early and make informed design decisions throughout development.

Whether you need support with a specific engineering task or a partner to guide your product from an initial idea to a validated, production-ready design, iterator.de provides flexible, hands-on expertise tailored to your project.

Our services

• Concept Development & Feasibility — Translating requirements and ideas into practical, technically viable product concepts.

• Industrial & Mechanical Design — Developing functional, well-considered product designs with a focus on usability, performance and manufacturability.

• CAD & Detailed Engineering — Creating 3D models, technical drawings, assemblies and engineering documentation.

• Prototyping & Testing — Building and evaluating physical prototypes to verify design decisions, identify weaknesses and refine functionality.

• Design for Manufacture & Assembly (DFMA) — Optimising designs for production processes, assembly efficiency, cost and repeatability.

• Production Readiness & Manufacturing Support — Preparing designs and documentation for supplier handover, small-series production and further industrialisation.

Practical engineering. Thoughtful design. Products built to last.

We believe good product development goes beyond producing a convincing concept or a detailed CAD model. It means understanding how a product will function, how it can be manufactured reliably and how it will perform throughout its service life.

With iterator.de, you gain a flexible development partner focused on technical quality, resource efficiency and turning ideas into viable physical products.

On-Demand Manufacturing & Low-Volume Spare Parts

Flexible manufacturing. Replacement parts when you need them.

iterator.de provides on-demand manufacturing for businesses that need functional components, small production runs and replacement parts without the cost and commitment of conventional mass production.

Combining in-house additive manufacturing with access to external production processes, we deliver practical solutions for one-off components, small batches and replacement parts for existing or discontinued products.

For OEMs and equipment manufacturers, maintaining spare-parts availability can be challenging when demand is unpredictable, minimum order quantities are high or conventional tooling is no longer economical. On-demand manufacturing offers an alternative: producing components as needed, reducing inventory commitments and helping extend the useful life of existing products.

Our engineering background means we look beyond the manufacturing process itself. We consider component function, material properties, dimensional requirements, production economics and intended service conditions to identify the most appropriate route from design data to finished part.

Whether you need newly designed components, replacement parts for equipment in service or a manufacturing solution for low-demand legacy parts, iterator.de provides flexible production support backed by practical engineering expertise.

Our services

• Replacement & Spare Parts — Manufacturing support for existing, hard-to-source or discontinued components, subject to technical feasibility and the necessary authorisations.

• Manufacturing Process Selection — Selecting suitable processes based on geometry, material, tolerances, functional requirements, quantity and cost.

• CAD Adaptation & Reverse Engineering — Recreating or modifying existing components where suitable reference data, permissions and inspection capabilities are available.

• Production Preparation & Quality Checks — Reviewing manufacturing data, defining acceptance criteria and documenting relevant inspection results.

• On-Demand 3D Printing — FDM and resin-based printing for prototypes, functional components, housings, covers, brackets and fixtures.

• Low-Volume Manufacturing — Individual components and small batches without unnecessary investment in dedicated tooling.

Make what you need. When you need it.

Manufacturing should be appropriate to the product, application and required quantity. Not every component needs expensive tooling, large production batches or long-term physical storage.

By combining engineering expertise, in-house production and external manufacturing capabilities, iterator.de helps businesses find practical alternatives for low-volume components and spare parts — supporting repairability, resource efficiency and longer product lifecycles.

From individual components to small production runs, we help keep products and equipment in service.

Practical 3D Printing & Product Development Training

Build skills. Understand the process. Make ideas tangible.

iterator.de offers practical training courses for groups, students and businesses looking to develop their skills in 3D printing, technical product design and rapid prototyping.

Our courses combine engineering fundamentals with hands-on experience, helping participants understand how digital designs become physical products. From first-time users learning additive manufacturing to enterprise teams exploring new production methods, training is adapted to the group's experience, objectives and available equipment.

For educational institutions, our workshops introduce students to modern product development, CAD and additive manufacturing through practical, project-based learning. For businesses, we focus on applying these technologies to real workflows, supporting faster prototyping, design iteration and more informed manufacturing decisions.

Training can cover the complete workflow, from developing a CAD model and preparing a print to selecting materials, operating equipment and evaluating the finished part. Participants gain practical experience while learning about design constraints, process limitations, material behaviour and the potential of additive manufacturing.

For groups looking to continue beyond the course, we also offer equipment-inclusive packages featuring a Prusa MINI+ 3D printer, giving participants or organisations a practical starting point for continued learning and experimentation.

Our training services

• 3D Printing Fundamentals — Understanding additive manufacturing, print technologies, materials and practical applications.

• CAD & Product Design — Learning the principles of 3D modelling, design for manufacturing and preparing parts for production.

• Hands-On Group Workshops — Practical sessions for students, educational institutions, clubs and professional teams.

• Enterprise Training — Tailored workshops exploring how 3D printing and rapid prototyping can support existing engineering and production workflows.

• Printer Starter Packages — Training packages incorporating a Prusa MINI+ printer to support continued practice after the course.

• Custom Training Programmes — Content and delivery adapted to participant experience, group size and learning objectives.

Learn by making.

The most effective way to understand a manufacturing technology is to work with it. Our training connects technical knowledge with practical application, helping participants build confidence, solve problems and recognise where 3D printing can deliver real value.

Whether you're introducing students to digital manufacturing or equipping a team with new prototyping capabilities, iterator.de provides accessible, engineering-led training with an emphasis on practical skills and lasting knowledge.
