Product Design Internship
Sketch, model, validate, render. You will take a product from a concept to a CAD model that could actually be manufactured, and present it like a real design studio.

Anyone can model a shape. Few can model a part
Wall thickness, draft angles, snap fits, tolerances, assembly order. The difference between a render and a product is whether a factory can make it.
- 1You sketch broadly and pick a direction with reasons
- 2You model parametrically so changes stay cheap
- 3Your mentor reviews it for manufacturability
- 4You render, prepare drawings and present
No prior CAD needed. Weeks 1 to 3 cover sketching and SolidWorks from zero.
Eight things you will actually be able to do
Design sketching
Fast concept sketching, perspective and communicating an idea in thirty seconds.
Parametric CAD
SolidWorks and Fusion 360 modelling with a feature tree that survives revisions.
Assemblies
Mates, sub-assemblies, interference checks and exploded views.
Design for manufacture
Wall thickness, draft, ribs, bosses, snap fits and injection moulding constraints.
Technical drawings
Dimensioning, tolerances, GD&T basics and drawings a factory can read.
Prototyping
3D printing for fit testing and iterating on physical prototypes.
Rendering
KeyShot materials, studio lighting and photoreal presentation images.
Presentation
Boards, exploded views and pitching a design to a non-designer.
The 12-week plan
Four phases. Each one ends in a deliverable that is reviewed and graded before the next opens.
Sketch and CAD
Ideas fast, then geometry precise.
- Concept sketching, perspective and ideation volume
- SolidWorks fundamentals, sketches and features
- Parametric thinking and a maintainable feature tree
- Reading a product brief and defining constraints
Thirty concept sketches narrowed to one direction, plus a first parametric CAD model.
Parts and assemblies
From one part to a product.
- Multi-body parts, surfacing and complex geometry
- Assemblies, mates and sub-assembly structure
- Interference detection and motion studies
- Design revisions without breaking the tree
A complete multi-part assembly with zero interferences and a clean, editable feature tree.
Manufacturability
Making it a product, not a shape.
- Wall thickness, draft angles, ribs and bosses
- Snap fits, fasteners and assembly sequence
- Material selection and process constraints
- 3D printed prototypes and fit testing
A DFM-audited assembly plus a printed prototype with a written fit and tolerance report.
Present it
Drawings, renders and the pitch.
- Technical drawings, dimensioning and tolerances
- KeyShot materials, studio lighting and renders
- Exploded views, boards and presentation layout
- Portfolio case study, CV rewrite, mock interview
A full product package: CAD, drawings, renders, prototype photos and a presented pitch.
Every intern designs one manufacturable product
You take a real brief (an enclosure, a consumer product, a fixture) from sketch through DFM-checked CAD to a prototype and a presented package.
- Parametric CAD that survives revisions
- Audited for manufacturability, not just looks
- Prototyped, rendered and presented







What every Ezitech intern gets
Three things that make this different from a course you watch on a screen.
Live client briefs
You work on real Ezitech projects with real deadlines and real revision rounds, not recycled practice exercises.
A mentor, not a playlist
Weekly reviews with someone who does this work for a living, plus a team of interns around you to build with.
Portfolio and experience letter
You finish with shipped work you are allowed to show and a letter that says exactly what you delivered.
Verified certificate
Issued by Ezitech Institute and verifiable by employers.
Experience letter
On company letterhead, stating exactly what you delivered.
A presented product
CAD, renders and a specification sheet for one product.
Interview preparation
CV rewrite, portfolio case study and a technical mock interview.
A route into the team
Top performers are considered first for paid junior roles.
Confidence in review
Twelve weeks of defending your own work to a senior practitioner.
Built for you if
- You are a student or fresh graduate in industrial design or mechanical engineering
- You like both the sketching and the engineering side
- You want portfolio work that shows CAD and presentation
- You are interested in how things are actually made
Not a fit if
- You want a certificate without doing the work
- You cannot give 25 hours a week for 12 weeks
- You are looking for a purely theoretical course
- You want to skip review and work alone
Questions people ask
Everything applicants email us about, answered before you apply.
Do I need to be good at sketching?
How many hours a week does it take?
Is it remote or onsite?
SolidWorks or Fusion 360?
Can final-year students apply?
How do I apply?
Not sure Product Design is the one?
Every 2D/3D architecture internship runs three months, hybrid, with the same mentor model. Or take the six-month All-in-One flagship.
3D Floor Plan
2D drawings turned into furnished, lit 3D plans that sell a space.
View trackCivil Architecture
Draft and model buildings to scale, then present walkthrough-ready renders.
View track2D/3D Animation
Rig, animate and render sequences from storyboard to composite.
View trackJewellery Design
Precision jewellery modelling with files ready for 3D printing.
View trackDesign something a factory could build
Three months, one shipped piece of real work, a mentor who reviews you every week. Registration takes five minutes.
