3D Printing and Prototype Design
Guenzo designs prototypes that exist to answer a question — fit, function, ergonomics, manufacturability. We prepare 3D-printable CAD, STL files, and iterate quickly between print rounds so you reach a working design with the fewest possible iterations.
Who this service is for
- Hardware startups validating concepts
- Product teams testing fit and function
- Companies needing visual or marketing prototypes
Problems we solve
- Prototypes that print but do not answer the engineering question
- Walls too thin, supports in the wrong place, parts warping
- Too many iterations between design and physical test
- No clear path from prototype geometry to production geometry
Deliverables
- 3D-printable CAD (FDM, SLA, SLS)
- STL and 3MF files
- Material and process recommendations
- Print-ready geometry (wall thickness, supports, orientation)
- Iteration plans between print rounds
Software we use
- SolidWorks for print-ready CAD
- Slicers for FDM / SLA / SLS preparation
- STL / 3MF / STEP exports
- KeyShot for visual prototypes
Supported manufacturing methods
- FDM (PLA, PETG, ABS, ASA, Nylon, Polycarbonate)
- SLA / DLP resin printing
- SLS (Nylon PA12)
- Multi Jet Fusion (MJF) for functional parts
- Low-volume CNC / sheet metal for bridge production
Example projects
- Functional prototype of an electronics enclosure
- Concept models for design reviews and pitches
- Jigs and fixtures for production lines
- Low-volume end-use parts
Process
- Define the question: What does this prototype need to prove?
- Design: Print-aware CAD with the right walls, supports and tolerances.
- Iterate: Adjust based on physical testing.
- Transition: Move proven prototype designs toward CNC or molding.
Frequently Asked Questions
Can you support prototyping?
Yes. We design prototype-ready CAD, provide STL files, and can manage print rounds and iteration with our supplier network.
Do you work with companies outside Latvia?
Yes. We work remotely with companies across Europe and internationally. Most projects are run by email, video calls, and shared cloud folders.
What CAD file formats can you deliver?
Native SolidWorks (SLDPRT, SLDASM, SLDDRW), STEP, IGES, Parasolid, STL for 3D printing, DXF for laser/waterjet/sheet metal, and PDF manufacturing drawings.
Can you sign an NDA before we share project details?
Yes. We routinely sign NDAs before reviewing concepts, sketches, or existing CAD data.
