- SLS and MJF review
- Metal printing feasibility review
- Post-processing and painting coordination
Service overview
Select the additive process around the prototype question.
Industrial 3D printing supports rapid evaluation when teams need to check geometry, assembly, handling, appearance, airflow, or functional behavior before committing to tooling or more expensive production processes.
SLA, SLS, MJF, and metal additive options serve different requirements. Process selection is reviewed against size, wall thickness, resolution, strength, temperature, surface, color, and the purpose of the prototype.

Key capabilities
Process planning connected to the drawing and end use.
The manufacturing route is reviewed around geometry, material behavior, critical features, appearance, inspection, and downstream assembly.

Typical parts
Parts commonly reviewed for 3d printing.
Appearance housings
Fit-check covers
Functional clips
Ducts and manifolds
Assembly fixtures

Industries
Applications supported across engineering teams.
Materials
Material options linked to technical guidance.
Surface Finishes
Surface Finishes reviewed for material and application fit.
Tolerances and design guidance
Define what is functionally critical.
Printed-part accuracy and surface depend on process, orientation, support strategy, geometry, material, post curing, and finishing. Critical fit features should be identified and may require secondary machining or design allowance.
DG 01
Choose the process based on the validation goal, not only appearance.
DG 02
Provide minimum wall, hole, and clearance needs for functional review.
DG 03
Expect support or build-orientation effects on selected surfaces.
DG 04
Mark surfaces that require sanding, painting, polishing, or secondary machining.
Quality assurance
Inspection planning starts with the drawing.
Inspection points are selected from the controlled drawing, functional risk, process behavior, appearance criteria, and documentation requested for the project.
Build file and revision check
Orientation and support review
Post-process dimensional and appearance inspection
Fit or assembly check when mating information is provided

Manufacturing workflow
A controlled route from RFQ to shipment.
The exact route changes with process and project risk, but each stage keeps the approved drawings and requirements in view.
- 01
Prototype objective review
Define whether the part is for form, fit, function, appearance, or testing.
- 02
Process and build planning
Select material, orientation, supports, build method, and finishing route.
- 03
Printing and post-processing
Build, clean, cure or depowder, finish, and inspect the part.
- 04
Validation handoff
Deliver parts with agreed inspection or assembly feedback support.

3D Printing questions from engineering and sourcing teams.
What should I provide for a 3D printing quotation?
Send a 3D CAD file when available, a 2D drawing for critical dimensions and tolerances, material, quantity, finish, inspection, and delivery requirements. An engineer reviews the package before quotation.
Which 3D printing process should I choose?
SLA is often reviewed for fine detail and appearance, SLS or MJF for durable nylon prototypes, flexible processes for soft parts, and metal additive for geometry that justifies the route. Final selection depends on the application.
Can printed parts be painted or machined?
Selected printed parts can be sanded, painted, polished, tapped, fitted with inserts, or secondarily machined. The base process and geometry must be compatible with the requested result.
How is lead time determined?
Lead time depends on geometry, material availability, quantity, tooling or setup requirements, surface finishing, inspection, and delivery needs. Timing is reviewed with the quotation rather than presented as a fixed promise.
