What is the difference between concept design and new product development (NPD)?

Concept design is the early ideation and industrial-design phase — sketches, form studies, and aesthetic direction. New product development (NPD) is the full end-to-end process that carries that concept through parametric CAD, mechanism design, DFM analysis, and prototyping until it is ready for production. Concept design is one phase inside a complete NPD program.

What is SPM engineering?

SPM stands for Special Purpose Machine — a custom-built machine designed for one specific task, such as automated assembly, inline inspection, or a dedicated manufacturing process, rather than a general-purpose machine tool. APJ 3D designs and engineers SPMs including mechanism layout, actuator selection, and control integration.

What deliverables do I receive from an APJ 3D NPD project?

Depending on project scope, deliverables typically include a concept design package, native parametric CAD models (NX, CATIA, Creo, or SolidWorks), 2D manufacturing drawings with GD&T, a bill of materials, a DFM/DFA feasibility report, and a functional prototype.

How long does a project take from concept to production-ready prototype?

Timelines vary with product complexity, but a typical concept-to-functional-prototype cycle runs through five phases — concept design, mechanism design, parametric modelling, DFM analysis, and prototype development — each with its own review and sign-off before moving to the next.

THE FUNDAMENTALS

What Is Concept Design & New Product Development?

Three connected disciplines, run as one workflow — from the first sketch to a production-ready, automated manufacturing line.

Concept Design

The earliest phase of building a physical product — industrial-design sketching, form studies, and aesthetic direction that balance how a product looks with how it needs to function.

New Product Development (NPD)

The full process that carries a concept through: parametric CAD, mechanism design and kinematics validation, DFM/DFA review, and a functional prototype ready for production. Concept design is the first phase inside it — not a separate service.

SPM Engineering

Special Purpose Machine design — for a custom assembly line, an inline inspection station, or a dedicated test rig. Run as an integrated part of the same NPD workflow, alongside the product itself.

ENGINEERING LIFECYCLE

Concept Design vs. NPD vs. SPM Engineering — Where Each One Fits

These aren't three competing services — they're three scopes of the same project, and most manufacturing programs need all three at different stages.
