Review the appearance
Evaluate proportions, visible surfaces, colour and texture with a sample you can handle.
CNC PROTOTYPES · 3D PRINTINGMake it tangible.
Make it tangible.
Refine it with confidence.
From appearance models to assembly and functional samples, combine CNC machining, 3D printing and finishing around the questions your prototype needs to answer.
Check the assembly
Review mounting points, interfaces, clearances and the order of assembly.
Evaluate the function
Agree the material and test conditions for the specific motion, load or environment being assessed.
01 / PROTOTYPING
Choose the route by what you need to verify
CNC and 3D printing serve different stages and features. A project can combine both, with acceptance requirements agreed for each part.
01 / CNC
CNC prototypes
Machine metal or engineering-plastic stock for samples with defined mating surfaces, holes, threads and structural features.
- Best discussed for
- Structural verification, material-based testing and machined interfaces.
- Review before machining
- Datums, critical dimensions, cutter access, thin walls and cosmetic areas.
02 / 3D PRINTING
3D printing for prototypes
Build samples layer by layer for shape reviews, intricate geometry and early assembly checks. Choose the process and material for the intended test.
SLA · Resin
Consider for detailed forms and appearance samples. Review support marks and the required surface finish.
SLS · Nylon
Consider for complex structural and assembly samples. Review texture, fit and the selected material properties.
For load, heat or repeated-use testing, confirm the specific grade, build orientation and test conditions.
FORM & SURFACE
Complex shapes, seen in detail
A sculptural sample brings fine textures, curved forms and the overall finish into view. Discuss the geometry, construction and surface target together before choosing a manufacturing route.
Fine surface detailCurves & transitionsAssembly & finish
02 / PROTOTYPING
Material and finish shape the result
Engineering plastics
ABS · PC · PMMA · POM
Match appearance, transparency, mating and use conditions to the exact grade.
Metal prototypes
Aluminum · Steel · Copper alloys
Consider rigidity, weight, contact surfaces and the final surface treatment.
Printing materials
SLA resin · SLS nylon
Review material data for the intended test; a similar appearance does not mean identical performance.
Surface preparation
Deburring, sanding and agreed surface refinement.
Appearance finishing
Review paint colour, texture, gloss and transparent surfaces against a sample.
Assembly details
Review threads, inserts, locating features and mating clearances.
03 / PROTOTYPING
A prototype should answer the right questions
Appearance & edges
Check agreed cosmetic areas, scratches, burrs, cleaning and transparent surfaces.
Dimensions & interfaces
Review critical dimensions, holes and threads against the approved revision.
Assembly & protection
Check specified mating parts; protect visible surfaces, thin features and threads for shipment.
04 / PROTOTYPING
A clear route from file to physical sample
- 01
Confirm drawings
Agree revision, quantity, material, critical features and the purpose of the sample.
- 02
Plan the process
Choose machining or printing; plan setups, toolpaths or build orientation.
- 03
Make & finish
Produce features and coordinate deburring, finishing and assembly details.
- 04
Inspect & deliver
Check agreed requirements, identify the revision and protect the parts for delivery.
05 / PROTOTYPING
Tell us what this prototype needs to prove
Include the model, drawing and sample purpose. We will review the process, finish and inspection requirements together.
Send your prototype enquiry- Model & drawing
- STEP / STP or IGES; pack printing STL files in ZIP; add a 2D drawing for critical dimensions.
- Purpose & quantity
- Appearance, fit or function; sample quantity and required date.
- Material & finish
- Grade, colour or reference sample, visible areas and assembly requirements.
06 / PROTOTYPING
Before you begin
Can you help choose between CNC and printing?
Send the model and explain the intended checks. We review material, geometry, fits and surface needs before recommending a route.
Can a printed sample replace a machined one?
It depends on the test. A shape model may answer an assembly question, while a load or thermal test may need a specific material and manufacturing process.
What affects cost and delivery?
Size, quantity, material, geometry, finishing and inspection all matter. Confirm these details before scheduling the work.
Can the prototype lead to repeat production?
After approval, review any changes in material, manufacturing route or acceptance criteria before a repeat order.
