3D modelling, visualisation and engineering design for product development.
I turn a sketch or a requirement into finished 3D geometry – engineered
on my own responsibility, agreed with you, and handed over in a form you
can actually work with.
Parts and assemblies, built parametrically so they stay editable –
from a sketch, from measurements taken off an existing part, or from
CAD data you already have.
SOLIDWORKS · Blender
Photorealistic visualisation
Renderings of products that do not exist yet – for quotations, trade
fairs, catalogues and internal decisions.
Blender
Product development
From the requirement through evaluated variants to production-ready
geometry – including cases where no drawing exists yet.
Concept · Variants · Detailing
Data preparation and handover
Design data prepared so that manufacturing, suppliers and sales can
work with it directly.
Manufacturing · Presentation · 3D printing
Animation and motion
Assembly sequences, operation and working principles as animation –
where a still image cannot show how something works.
Assembly · Operation · Working principle
Process
How a project runs
You describe the goal – I make the engineering and design decisions and
put them to you for approval.
Briefing
What needs to be built, and what already exists. You get an estimate of the effort up front, as a fixed price if you prefer.
Concept and engineering
I develop the solution myself – model structure, joining principle, and for visualisations the composition and lighting.
Review
Intermediate results as views or test renders. Two revision rounds are included.
Handover
Result data in the agreed formats. Source files are kept so changes remain possible later.
Projects
What I have worked on
Commissioned work for a manufacturer of water fittings and water
treatment equipment, an ongoing project in medical technology, and one
product development of my own. For the commissioned work I will name the
clients and the products on request.
Engineering · Product development
Pleen – fully automatic raised bed
A development of our own: a raised bed that waters its own plants.
Water tank, pump, filter and soil sensors sit in the base unit, and
an app guides the owner through the growing cycle.

Engineering · Visualisation
Fitting family with cantilever arm
One fitting across several equipment levels: parametric models from
which every variant can be derived.

Device for medical technology
Ongoing commission: engineering and visualisation of a medical
device, plus animations showing assembly and operation.
The concept is currently in the patent application stage, so no
image is shown yet. I will publish the rendering as soon as the
client has released it. I am happy to show you work samples
directly on request.
About
Briefly, about me
I am Lian Sessinghaus. I work from Wetter an der Ruhr in western Germany
and have been freelancing as a 3D modeller and visualiser since
13 November 2025. Engineering is done in SOLIDWORKS,
modelling and rendering in Blender. Projects run
remotely across Europe.
Contact

Write me a short note about what you want built – a hand sketch is
enough to start. I usually reply within 24 hours on working days.
