Rapid prototyping examples from real manufacturing projects are the most reliable guide to what a supplier can actually deliver — more reliable than capability lists, more revealing than certifications, and more useful for setting accurate expectations than any price guide. This page documents eight rapid prototyping examples from Manufyn’s workshop: real projects, real clients (anonymised where confidentiality applies), real technologies, real lead times, and real cost outcomes.
Each rapid prototyping case study describes the client’s engineering challenge, the technology selected and why, the DFM issues identified and resolved, the rapid prototyping product outcome, and the path from prototype to production where applicable. These examples of rapid prototyping cover medical devices, aerospace, automotive, consumer electronics, HVAC, jewelry, defence, and sheet metal enclosures — the eight primary industry verticals Manufyn serves.

Example 1: Medical Device Surgical Instrument Housing SLA + CNC, USA
Client and Project Background
A medical device startup based in Indianapolis, Indiana was developing a Class II surgical instrument for minimally invasive orthopaedic procedures. The product required a rigid polymer housing (for the first validation prototype) transitioning to stainless steel 316L for production. The engineering team needed 6 physical rapid prototyping product samples for an FDA pre-submission meeting — 3 in polymer for ergonomic evaluation, 3 in stainless for dimensional verification.
Technology Selected Why SLA and CNC
The ergonomic evaluation samples were produced in SLA biocompatible resin (ISO 10993 Class I) — the correct rapid prototyping material for a Class II medical device housing that will be handled by surgeons and evaluated for grip comfort, button reach, and instrument balance. The dimensional verification samples were produced in CNC stainless steel 316L — required because the FDA pre-submission dimensional report must reference samples produced by or closely equivalent to the intended production process. See the full medical device rapid prototyping guide for FDA documentation context.
DFM Issues Identified and Resolved
- SLA parts: wall thickness in two areas below the minimum stable thickness for the SLA resin. Resolved by adding 0.3mm to wall thickness in affected areas no functional impact.
- CNC stainless parts: a through-hole feature with L/D ratio of 8:1 required gun-drilling rather than standard CNC drilling. Flagged in DFM, customer agreed to increase hole diameter from 3mm to 4mm to allow standard CNC deep drilling.
- Both part types: NDA signed and counter-signed before drawing review. IP protection confirmed before any DFM analysis began.
Rapid Prototyping Product Outcome
- SLA biocompatible resin samples (3 pieces): 3 working days fabrication + 4 days air freight to Indianapolis = 7 days door-to-door
- CNC stainless 316L samples (3 pieces) with FAIR: 7 working days fabrication + 4 days air freight = 11 days door-to-door
- Cost: SLA 3 pieces total USD 620 | CNC 316L 3 pieces with FAIR USD 1,840 | combined rapid prototyping services cost USD 2,460
- US domestic equivalent rapid prototyping services cost (quoted by client’s previous supplier): USD 6,800
- Saving: 64%
- Outcome: FDA pre-submission meeting proceeded on schedule. SLA ergonomics samples led to three minor design changes which were incorporated in a second CNC iteration before production commit.
Example 2: Aerospace Topology-Optimised Bracket DMLS Ti6Al4V, UK
Client and Project Background
An aerospace Tier-1 supplier in Bristol, UK was developing a structural bracket for a commercial aircraft interior installation. The production bracket required topology optimisation reducing mass by 40% versus the conventional machined design while maintaining structural compliance under the specified load case. The engineering team needed 4 DMLS titanium rapid prototyping product examples for structural testing under AS9100 first article requirements.
Technology Selected Why DMLS Titanium
The topology-optimised geometry contained lattice infill structures and curved load paths that cannot be machined by any CNC process. DMLS in Ti6Al4V Grade 23 was the only feasible rapid prototyping method. The part required CNC post-machining of the two mating bolt holes to achieve the ±0.05mm positional tolerance called out in the drawing a common hybrid DMLS + CNC approach for aerospace rapid metal prototypes. See rapid prototyping for aerospace for the full context of AS9100 documentation requirements.
DFM Issues Identified and Resolved
- DMLS support structure design: the original orientation would have placed supports inside an internal channel, making removal impossible without damage. Manufyn’s DFM team recommended a 15° reorientation and modified support design customer approved.
- Post-machining datum setup: the bolt hole positions required a custom fixture for CNC post-machining to hold the DMLS part accurately. Manufyn designed and built the fixture in-house as part of the project.
Rapid Prototyping Product Outcome
- DMLS Ti6Al4V 4 pieces + CNC post-machining of bolt holes + AS9100 FAIR: 12 working days fabrication + 4 days air freight to Bristol = 16 days door-to-door
- Cost: USD 6,200 for 4 pieces with FAIR documentation, mill certificates, and CMM report
- UK domestic rapid prototyping services cost equivalent: GBP 8,400 (approximately USD 10,500) for 4 pieces
- Saving: 41%
- Outcome: all 4 samples passed structural testing at first attempt. The bracket is now in low-rate initial production with Manufyn supplying 50 pieces per quarter.

Example 3: Consumer Electronics Enclosure Vacuum Casting, Singapore
Client and Project Background
A consumer electronics startup in Singapore was developing a smart home IoT hub for market launch at CES. They needed 25 production-equivalent cosmetic samples in the launch colourway (RAL 9010 gloss white) for press reviews, retail buyer presentations, and regulatory pre-submission packaging assessment. Budget was constrained — full injection mould tooling was not viable before product launch confirmation.
Technology Selected — Why Vacuum Casting
Vacuum casting rapid prototyping was the correct choice: production-equivalent cosmetic quality, the correct quantity (25 pieces) within a silicone mould’s lifespan, production-equivalent ABS-like polyurethane in the specified gloss white colour without painting, and a rapid prototyping services cost 60% lower than 25 pieces of CNC machined and painted parts. See casting and moulding for rapid prototyping for the full vacuum casting process description.
Rapid Prototyping Product Outcome
- 25 vacuum cast ABS-like polyurethane pieces in RAL 9010 gloss white: 13 working days fabrication (SLA master + silicone mould + 25 shots) + 2 days air freight to Singapore = 15 days door-to-door
- Rapid prototyping cost: SGD 3,800 (approximately USD 2,840) for the full batch of 25 pieces
- Singapore domestic rapid prototyping services cost equivalent: SGD 9,500+ for equivalent quality
- Saving: 60%
- Outcome: product received positive press at CES. Three cosmetic changes were made after CES, a new silicone mould was produced from an updated SLA master, and 30 additional samples were produced for retail buyer presentations before production tooling was committed.
Example 4: Automotive EV Battery Enclosure Sheet Metal, Australia
Client and Project Background
An Australian automotive aftermarket company in Melbourne was converting a classic vehicle to full electric drivetrain. The EV battery enclosure was a custom multi-component sheet metal assembly in 3mm mild steel, powder-coated satin black, with welded corner joints and internal aluminium extrusion mounting rails. They needed 3 first-article prototypes for vehicle fitment validation, weight measurement, and customer presentation.
Technology Selected Why Sheet Metal
Sheet metal rapid prototyping was the only correct choice: the production assembly would be mild steel, the fitment validation required real sheet metal bend angles and welded corner geometry, and the weight measurement required actual material density. A 3D-printed or CNC-machined model would have answered none of these questions. See sheet metal rapid prototyping guide for full process details.
Rapid Prototyping Product Outcome
- 3× mild steel DC01 sheet metal assemblies (4 components each), MIG welded, powder-coated RAL 9005 satin black, with aluminium mounting rails: 10 working days fabrication + 6 days air freight to Melbourne = 16 days door-to-door
- Cost: AUD 3,200 (approximately USD 2,100) for 3 complete assemblies
- Melbourne domestic rapid prototyping services cost equivalent: AUD 7,800 for equivalent work
- Saving: 59%
- Outcome: fitment validated. Two bracket positions needed adjustment a second iteration was produced in 8 working days. Production is now at 50 assemblies per year through Manufyn’s sheet metal fabrication service.
Example 5: HVAC Ductwork Prototype Sheet Metal, UAE
Client and Project Background
A Dubai HVAC contractor was tendering for a large commercial building fit-out and needed fabricated prototype ductwork sections and transitions to demonstrate fit and quality to the building client before awarding the supply contract. Three duct sections (rectangular 400×250mm, 1.5m length) and two 90° elbows in 1mm galvanised steel DX51D+Z275 were required within 10 days.
Rapid Prototyping Product Outcome
Galvanised steel ductwork sections and elbows fabricated and air-freighted to Dubai in 9 working days total (7 fabrication + 2 days air freight to UAE). Cost: AED 4,200 (approximately USD 1,145). Dubai domestic rapid prototyping services cost equivalent: AED 9,800. Saving: 57%. Outcome: the contractor won the tender. Manufyn is now supplying all production ductwork for the project see sheet metal fabrication HVAC guide for details on HVAC sheet metal fabrication capabilities.
Example 6: Jewelry Investment Casting Pattern SLA, Germany
Client and Project Background
A jewelry designer in Munich was producing a limited edition ring collection in 18-carat yellow gold. The complex floral motif required investment casting — the geometry was too intricate for CNC or stamping. SLA castable resin patterns were needed for the lost-wax casting process at a German goldsmith workshop.
Technology Selected Why SLA Castable Resin
SLA castable resin is the standard rapid prototyping material for lost-wax investment casting. The resin burns out at ceramic firing temperatures without carbonaceous residue that would contaminate the metal casting. See jewelry and luxury goods rapid prototyping for the full SLA-to-investment-casting workflow.
Rapid Prototyping Product Outcome
- 12× SLA castable resin ring patterns: 2 working days fabrication + 5 days air freight to Munich = 7 days total
- Cost: EUR 380 (approximately USD 415) for 12 patterns
- German domestic rapid prototyping services cost equivalent: EUR 850–1,100
- Saving: 55–65%
- Outcome: all 12 castable patterns burned out cleanly. Gold castings passed quality review. The collection sold out within 3 weeks of launch.
Example 7: Industrial Drone Airframe SLS Carbon Nylon, Canada
Client and Project Background
A Canadian drone technology company in Edmonton was developing a heavy-lift industrial drone for oil-field inspection. The airframe arm assemblies required carbon-filled PA12 SLS nylon for maximum stiffness-to-weight ratio. 6 arm assemblies were needed for the first full flight test prototype build.
Rapid Prototyping Product Outcome
6× SLS carbon-filled PA12 drone arm assemblies: 5 working days fabrication + 6 days air freight to Edmonton = 11 days total. Cost: CAD 2,100 (approximately USD 1,555). Edmonton domestic rapid prototyping services cost equivalent: CAD 5,200. Saving: 60%. Outcome: airframe passed 40-flight test cycle. Manufyn is now producing 50 sets of arm assemblies per quarter for the production version. See rapid prototyping for defence and aerospace suppliers and rapid prototyping services in Canada for the full Canadian context.
Example 8: CNC Stainless Steel Hydraulic Manifold CNC, Germany
Client and Project Background
A German industrial machinery manufacturer in Stuttgart needed a CNC stainless steel 316L hydraulic manifold prototype for pressure-cycle testing. The manifold had 8 ported faces, 4 internal intersecting channels, and 3× M16 thread ports. ISO 2768-f tolerance on all critical features. FAIR and hydrostatic pressure test to 350 bar required.
Rapid Prototyping Product Outcome
2× CNC 316L SS hydraulic manifold prototypes with FAIR and hydrostatic pressure test documentation: 10 working days fabrication + 5 days air freight to Stuttgart = 15 days total. Cost: EUR 3,400 (approximately USD 3,700) for 2 pieces. German domestic rapid prototyping services cost equivalent: EUR 7,800. Saving: 56%. Outcome: both manifolds passed hydrostatic testing at 350 bar. See CNC rapid prototyping guide and rapid prototyping services in Germany for full CNC capability and German market details.
