One Order, Two Processes — How Combined SLS and SLA Transparent 3D Printing Solved a Security Electronics Manufacturer's Multi-Variety Small Batch Challenge
When a security equipment company needed 28 components across 5 different part types — including durable structural housings and a fully transparent waterproof enclosure — traditional manufacturing presented a dilemma: which process to choose for such a diverse mix?
The answer: both. This article presents a real-world delivery case demonstrating how ChanHonTech's combined SLS (Selective Laser Sintering) and SLA (Stereolithography) 3D printing services enabled a single-order, dual-process solution — eliminating mold costs, compressing lead times, and delivering all 28 parts as a unified batch. For manufacturers across ASEAN facing similar multi-material prototyping needs, this case illustrates a practical path to faster, more flexible product development.

1. Industry Background: The Security Electronics Manufacturing Landscape
The global security electronics market — encompassing access control systems, video surveillance, intrusion alarms, and electronic locks — was valued at approximately $58.2 billion in 2025 and is projected to grow at a CAGR of 8.4% through 2030 [est. based on industry reports]. The Asia-Pacific region accounts for over 35% of this market, with Southeast Asia's security infrastructure investment accelerating significantly.
Vietnam's security equipment imports have grown steadily, driven by urban infrastructure development, smart city initiatives, and industrial park expansions [est.]. Indonesia, as Southeast Asia's largest economy, similarly shows rising demand for electronic security products across both commercial and residential sectors.
Manufacturers in this sector face a persistent challenge: product variety is high, batch sizes are small. A typical electronic security product — such as an access control panel or alarm system — may require 8–15 distinct plastic components: housings, brackets, covers, buttons, indicator windows, and cable management parts. Each component has unique material and functional requirements.
| Manufacturing Challenge | Impact on Security Equipment R&D |
|---|---|
| Multi-variety parts per product | 8–15 different components per device [est.] |
| Small prototype batches | 4–8 pieces per part type, not thousands |
| Mixed material requirements | Some parts need strength; others need transparency |
| Frequent design iterations | 2–4 design cycles before finalization [est.] |
| Time-to-market pressure | Competitive launches demand rapid prototyping |
The combination of these factors makes traditional mold-based manufacturing economically unviable at the R&D and early production stages. This is where industrial-grade 3D printing — particularly the combination of SLS and SLA processes — provides a compelling alternative.
2. Technical Solution: SLS + SLA — Two Processes, One Supplier
ChanHonTech equipped the security electronics manufacturer's prototyping needs by deploying two complementary additive manufacturing technologies in a single production batch:
SLS — Selective Laser Sintering (Black-like ABS Nylon)
SLS uses a CO₂ laser to sinter nylon powder particles layer by layer, producing durable, impact-resistant parts with ±0.3mm accuracy. SLS nylon offers mechanical properties comparable to injection-molded ABS — making it the preferred choice for structural components such as housings, brackets, covers, and load-bearing parts.
SLA — Stereolithography (Transparent Resin)
SLA uses a UV laser to cure liquid photopolymer resin layer by layer, achieving ±0.1mm accuracy and smooth surface finishes. Transparent SLA resin was specifically chosen for the waterproof box component, enabling visual inspection of internal electronic assemblies while maintaining the enclosure's integrity.
| Parameter | SLS (Polyamide / Nylon 12) | SLA Transparent Resin |
|---|---|---|
| Material | PA12 (Nylon) — Black-like | UV-curable transparent resin |
| Layer Thickness | 0.08–0.12mm | 0.05–0.1mm |
| Dimensional Accuracy | ±0.3mm | ±0.1mm |
| Tensile Strength | 48 MPa | 48–52 MPa |
| Elongation at Break | ~20% | ~10–15% |
| Surface Finish | Slightly textured (matte) | Smooth, can be polished to clear |
| Heat Deflection Temp | ~90°C | ~60°C |
| Max Build Size | 600 × 600 × 400mm | 600 × 600 × 400mm |
| Post-Processing | Tumbling, dyeing, sealing | Wash, UV cure, sand, polish |
All specifications based on industrial-grade Farsoon equipment operated by ChanHonTech, a Farsoon-authorized service provider.
3. Small-Batch Manufacturing Comparison: 3D Printing vs Injection Molding vs CNC Machining
For the security electronics manufacturer's specific requirements — 28 parts across 5 part types — the table below compares the three available manufacturing approaches:
| Criteria | Injection Molding | CNC Machining | 3D Printing (SLS + SLA) |
|---|---|---|---|
| Tooling Investment | ★★★ $12,000–$40,000 (5 molds) | ★★☆ Moderate (programming) | ★☆☆ Zero (no mold needed) |
| Lead Time (28 parts) | 4–6 weeks | 5–10 business days | 2–4 business days |
| Multi-Variety (5 types) | Separate mold per type | Separate program per type | Single file batch, no extra cost |
| Mixed Materials in One Order | Requires separate lines | Difficult for transparent parts | SLS + SLA seamless |
| Minimum Quantity | 1,000+ pieces | 1 piece OK (but high unit cost) | 1 piece OK |
| Design Change Cost | $3,000+ per mold revision | Moderate (re-program) | Free (edit 3D file) |
| Surface Quality | Excellent | Excellent | Good (SLS matte / SLA smooth) |
"Using a single supplier for both SLS structural parts and SLA transparent parts streamlined our entire prototyping process. One RFQ, one order, one delivery — two material properties." — ChanHonTech Database, Real customer delivery record, 2026
4. Real Case Study: 28-Piece Security Equipment Component Set
The Client
Shenzhen Gujin Security Technology Co., Ltd. — a security and safety electronic equipment manufacturer based in Shenzhen, China. Their products encompass access control systems, surveillance equipment, alarm systems, and related electronic security hardware.
Close-up of the 3D printed security equipment prototype set — the transparent SLA resin enclosure allows visual inspection of internal electronics.
The Requirement
The client needed a complete set of prototype components for an electronic security device. The order comprised 5 distinct part types totaling 28 pieces, each with specific material and functional requirements:
| Part Type | Material Requirement | Function |
|---|---|---|
| Handle Cover | Durable, impact-resistant (SLS black ABS-like) | Mechanical engagement, daily use |
| Battery Cover | Dimensionally stable, snap-fit capability (SLS) | Secure battery compartment closure |
| Cable Protection Cover | Flexible, durable (SLS) | External cable routing protection |
| Motherboard Bracket | Rigid, precise mounting (SLS) | Internal PCB mounting structure |
| Waterproof Box | Transparent, sealed enclosure (SLA transparent resin) | Internal component visibility + sealing |
The Challenge
With only 4–8 pieces needed per part type, the economics of injection molding were prohibitive: 5 separate molds would cost tens of thousands of dollars — an unacceptable investment for a prototype run. CNC machining could produce individual parts, but combining opaque structural parts with a clear transparent component would require different material feeds, multiple setups, and extended lead times.
The Solution
ChanHonTech proposed a unified dual-process approach:
- 4 structural part types → SLS black-like ABS nylon — delivering durability, impact resistance, and the ability to test snap-fits and mechanical assembly
- 1 transparent enclosure → SLA transparent resin — delivering optical clarity for internal electronics inspection while maintaining a waterproof enclosure design
- All 28 parts coordinated as a single order, in a single production slot, shipped as one batch
The Results
| Metric | Traditional (Mold + CNC) | 3D Printing (SLS + SLA) | Improvement |
|---|---|---|---|
| Total Cost (prototype) | $12,000–$40,000 (5 molds) | Under $2,000 [est.] | ~90% savings |
| Lead Time | 4–6 weeks | 2–4 business days | ~85% faster |
| Material Processes | 2+ suppliers needed | 1 supplier, 2 processes | Streamlined |
| Design Flexibility | Costly to change | Free design iteration | Highly agile |
| Part Precision | ±0.1mm (mold) | ±0.1–0.3mm | Functional fit OK |
"For our security equipment prototype run, having both SLS black ABS and SLA transparent parts from the same supplier simplified logistics and eliminated mold costs entirely. The dual-process approach was exactly what we needed." — Client Engineering Team [ChanHonTech Database — Real customer delivery record, 2026]
