What is Rapid Prototyping?
Using digital manufacturing (CNC, additive, sheet metal, soft tooling) to convert CAD into physical parts quickly so teams can validate form, fit, function—and iterate without friction.
Why Choose KaiSpeed
Our Rapid Prototyping Services
Rapid CNC Prototyping Service
CNC milling and turning are ideal when you need parts in their final production materials. We machine from fully dense stock to deliver accurate, durable prototypes that behave like end-use parts—perfect for functional, thermal, optical, and assembly tests.
Metals (Al/steel/SS/brass/copper/titanium) and plastics (ABS/PC/POM/PEEK/PEI)
Finishes: bead-blast, anodize, hard-coat, chromate, passivation, plating, powder/paint, polish
CNC Milling: 3-/4-/5-axis milling, Milled plastic and metal parts
CNC Turning: All types of round CNC machined parts
CNC Grinding: Tight tolerance and good surface
CNC EDM: For deep pockets and sharp corners
Rapid Sheet Metal Prototyping
Fast, economical prototypes in final metals for enclosures, brackets, and chassis. We combine laser cutting, CNC bending, hardware insertion (PEM®), spot/TIG/MIG welding, and finishing for one-stop delivery.
Profile tolerance: ±0.10–0.20 mm
Bend angles: ±1–2° with proper setup
DFM guidelines: min slot/hole ≥ 1× t；hole-to-bend ≥ 1.5× t + R；inside radius start at ≈1× t (increase for 6061-T6/SS)
Rapid Prototype Injection Molding
When you need material-true prototypes or pilot runs, rapid tooling delivers repeatable parts with production-like behavior. We build aluminum or soft-steel tools, including family tools, insert-molding, and overmolding.
Materials: ABS/PC/PC+ABS/PA/PP/POM/PMMA/TPE/TPU/PEEK, etc.
Docs: Molding to drawing, QC reports, COC/material certs, FAI on request
Rapid Vacuum Casting Prototyping
Perfect for 5–50+ sets of cosmetic or elastomer parts with injection-mold-like look/feel—fast and cost-effective. We cast from SLA master patterns into silicone tools, offering rigid, clear, and rubber-like resins.
Shore hardness: 20A–90A, 60D+ rigid grades; tint/texture options
Lead time: up to ~20 parts in 7–15 days including pattern and curing
Rapid 3D Printing Prototyping
Fastest iteration for complex geometry. Choose SLA (cosmetic & clear), SLS/MJF (functional nylon), or FDM (large format & engineered thermoplastics). TPU options for flexible parts/seals.
SLA: smooth surfaces, clear/translucent; appearance models
SLS/MJF (PA12/PA11): durable functional parts, lattice structures
FDM: larger builds in ABS/PC/ASA/PEI (ULTEM)

We Support — From Prototyping to Production
Rapid Prototyping & Design Validation
Build fast, learn fast. We ship parts in days so you can validate form/fit/function, finalize materials and finishes, and iterate with low risk.
What you get: Engineer-led DFM, photos/build notes, golden samples, optional inspection reports (CMM/FAI).
Pilot Runs to Scaled Production
De-risk scale-up with bridge tooling and fixtures, then ramp to stable, repeatable output. We lock cycle times, yields, packaging, and logistics.
What you get: PPAP/CPK/SPC on request, control plans, lot traceability, consistent cosmetics, and flexible fulfillment (kanban/stock-&-release).
FAQs
It converts CAD into physical parts quickly so teams can test form/fit/function, gather feedback, and iterate—reducing risk before tooling and production.
CNC: best accuracy & end-use materials
SLA/SLS/MJF/FDM: fastest iteration & complex geometry
Sheet metal: enclosures, brackets, chassis in final metals
Vacuum casting: cosmetic sets & elastomers, 5–50+ pcs
Rapid tooling: material-true parts & pilot runs
CNC: typically ±0.05–0.10 mm (tighter by feature)
SLA/SLS/MJF: around ±0.2 mm (size/geometry dependent)
Sheet metal: ±0.1–0.2 mm profile, ±1–2° bends
We’ll confirm achievable tolerances during DFM.
Yes. We support mutual NDAs, secure file handling, and restricted vendor routing as required.
No strict MOQ—single prototypes to low-volume and bridge builds.
Yes—threaded inserts, bonding, fasteners, light assembly, plus anodize, powder/paint, plating, passivation, dye/texture, and laser marking.
Many projects ship in days after DFM approval. Send your CAD for a quote with schedule options; expedites available.
