Processing methods of toy prototypes refer to the techniques used to transform design concepts into physical toy models—each method differs in cost, Präzision, and suitability for specific toy types (Z.B., Aktionszahlen, plush toys, or mechanical toys). Choosing the right method is critical for validating design feasibility, Testfunktionalität, und Beschleunigung von Zeit zu Markt. This article breaks down the core processing methods, ihre Workflows, comparative strengths, troubleshooting tips, and real-world applications to help toy developers make informed decisions.
1. What Are the Core Processing Methods of Toy Prototypes?
Each method is tailored to different toy complexities, batch sizes, and budget constraints. The table below details their key traits, Workflows, und ideale Anwendungsfälle.
Verarbeitungsmethode | Kernprinzip | Schritt-für-Schritt-Workflow | Ideal Toy Types | Schlüsselvorteile |
3D Druck | Layer-by-layer deposition of plastic (PLA, ABS) or resin to build 3D models from digital designs. | 1. Modellvorbereitung: Export 3D CAD files (STL -Format) and optimize for printing (Fügen Sie Unterstützung für Überhänge hinzu).2. Parametereinstellung: Choose layer thickness (0.1–0.2mm for smooth surfaces), Füllung (10–30% for structural stability), und Druckgeschwindigkeit (30–60 mm/s).3. Druckenausführung: Load filament/resin into the printer (FDM für PLA/ABS; SLA for resin) and start printing.4. Nachbearbeitung: Entfernen Sie Stützen mit Zangen, sand with 200–1000 grit sandpaper, and polish to remove layer lines. | Complex-shaped toys: Action figures with movable joints, puzzle toys with intricate grooves, or miniaturized models. | – Schnelle Turnaround (4–24 hours per prototype).- No mold needed (low upfront cost for small batches: 1–10 Einheiten).- Erfasst schöne Details (Z.B., 0.5mm-thick facial features on a doll). |
CNC Fine Carving | Computer-controlled cutting tools remove material from solid blocks (Plastik, Holz, oder Metall) to shape toy parts. | 1. Design Import: Convert 3D models to G-code (machining instructions) using software like Mastercam.2. Materialfixierung: Secure the material block (Z.B., POM plastic, Acryl, or aluminum alloy) to the CNC machine bed.3. Toolpath Optimization: Set cutting depth (0.1–0,5 mm pro Pass) and tool speed (10,000–15.000 U/min) to avoid overheating.4. Carving & Fertig: Machine the part, then sand (400–800 Grit) or sandblast the surface to improve smoothness. | High-precision toys: Mechanical toy gears, wooden toy blocks, or metal toy components (Z.B., hinges for a toy box). | – Ultrahohe Präzision (±0.05mm for critical features like gear teeth).- Durable parts (suitable for load-testing, Z.B., a toy car’s axle).- Works with rigid materials (Z.B., POM for wear-resistant toy wheels). |
Silikonformung & Replication | A master prototype (3D-printed or CNC-machined) is used to create a silicone mold, which is then filled with materials like PU resin to produce multiple copies. | 1. Master Prototype Making: Create a high-quality master (Z.B., a 3D-printed resin toy figure).2. Silicone Mold Production: Encase the master in a mold box, pour liquid silicone (500–2000 cP viscosity), and cure at 25–80°C for 4–24 hours.3. Entformen & Replication: Remove the master to reveal the mold, then inject PU resin/epoxy into the mold and cure.4. Trimmen & Montage: Cut off excess material (Tormarken) and assemble multi-part toys (Z.B., a toy robot’s body + Waffen). | Small-batch toy production: 10–50 units of a doll, toy animal, or decorative toy (Z.B., Christmas ornaments). | – Cost-effective for batches (lower per-unit cost than 3D printing).- Preserves master details (Z.B., texture on a toy’s fur or clothing).- Fast replication (3–5 days per batch). |
Handwerk | Manual shaping of materials (clay, Holz, Schaum, or fabric) using tools like carving knives, Kleber, and paint—ideal for artisanal or one-off toys. | 1. Materialauswahl: Choose clay (for sculpting), Schaum (for soft toys), oder Holz (for traditional toys like wooden trains).2. Gestaltung & Bildhauerung: Carve, Schimmel, or sew the material into the toy’s shape (Z.B., sculpt a clay doll’s face or sew a plush teddy bear).3. Fertig: Sand wooden parts, paint details (Z.B., eyes, Muster), and add accessories (Z.B., a toy’s hat or scarf). | Artisanal toys: Custom plush toys, hand-painted ceramic figures, or traditional wooden toys (Z.B., a hand-carved top). | – No specialized equipment needed (lowest upfront cost).- High customization (easy to adjust designs on the spot).- Suitable for unique, non-replicable toys (Z.B., a one-of-a-kind art doll). |

- Choice: Handwerk. It allows full customization (embroidery, fabric selection) without equipment constraints.
3. What Are the Critical Post-Processing Steps for Toy Prototypes?
Post-processing enhances appearance, Funktionalität, and safety—critical for toy prototypes (especially those for children).
3.1 Oberflächenbearbeitung
Schritt | Zweck | Verfahren & Werkzeuge | Beispiel |
Schleifen & Polieren | Remove processing marks (Ebenenleitungen, tool scratches) and create smooth surfaces (avoids sharp edges). | – Sand with 200→400→800→1000 grit sandpaper (grob bis gut).- Polish with polishing paste (Ceriumoxid) and a soft cloth for a glossy finish. | Sanding a 3D-printed doll’s face to eliminate layer lines; polishing a CNC-machined wooden toy car to a smooth shine. |
Färbung & Dekoration | Match design aesthetics (Farben, Muster) and add brand identity (Logos, safety labels). | – Spray Coating: Apply primer (für Haftung), base color (acrylic/model paint), and protective paint (matt/glänzend).- Water Transfer Printing: Add complex patterns (Z.B., cartoon skin, camouflage) to curved surfaces (Z.B., a toy truck’s body).- Seidenvorführung: Print small details (Z.B., “Ages 3+” labels, Markenlogos) on flat surfaces. | Spraying a toy robot’s body blue; using water transfer to add tiger stripes to a plush toy’s fabric. |
3.2 Montage & Funktionstests
Schritt | Zweck | Verfahren & Werkzeuge | Beispiel |
Komponentenbaugruppe | Join multiple parts (Z.B., a toy’s head + Körper + limbs) securely and safely. | – Glue: Use non-toxic instant glue (für Plastikteile) or fabric glue (for plush toys).- Befestigungselemente: Use small screws (M2–M3) für mechanische Teile (Z.B., Spielzeuggänge) or snaps for easy disassembly. | Gluing a doll’s arm to its body; using snaps to attach a toy’s removable hat. |
Funktionale Validierung | Ensure moving parts work smoothly and safely (no jamming or breakage). | – Test joint mobility (Z.B., bend a toy’s leg 100 times to check for durability).- Verify electronic features (Z.B., a toy’s sound module plays the correct “beep” when a button is pressed). | Testing a toy car’s wheels to ensure they spin freely; checking a light-up toy’s battery life (≥8 hours of use). |
3.3 Safety Compliance
Schritt | Zweck | Verfahren & Standards | Beispiel |
Edge Blunting | Eliminate sharp edges (hazard for children under 3). | File or sand edges to a radius of ≥0.5mm; use a deburring tool for CNC-machined parts. | Blunting the edges of a wooden toy block to avoid splinters. |
Small Part Check | Ensure no detachable parts (≤3cm) pose choking hazards (per ASTM F963 or EN 71 Standards). | Use a “choking hazard tester” (a 31.75mm diameter cylinder) to check if parts fit inside—if they do, secure them with glue. | Gluing a toy’s small button eyes to its face to prevent detachment. |
4. What Are Common Problems & Troubleshooting Tips?
Even with careful processing, issues can arise—here’s how to fix them.
Problem | Grundursache | Lösung |
3D Printing Layer Lines Visible on Toy Surfaces | Layer thickness too high (≥0.2mm); insufficient post-processing. | – Reduce layer thickness to 0.1–0.15mm during printing.- Sand with 800→1000→2000 grit sandpaper, then polish with paste. |
CNC-Machined Toy Parts Have Rough Surfaces | Cutting tool dull; feed rate too high. | – Replace the cutting tool with a sharpened one (Z.B., carbide end mill).- Reduce feed rate by 20–30% (Z.B., from 1000mm/min to 700mm/min).- Sandblast the surface for a uniform matte finish. |
Silicone Mold Deforms During Replication | Silicone hardness too low (<50A); no release agent used. | – Use higher-hardness silicone (70A - 80a) for the mold.- Apply a silicone-compatible release agent (Z.B., petroleum jelly) to the master before mold making. |
Handcrafted Toy Has Uneven Paint Coverage | Paint applied too thick; brush strokes visible. | – Apply 2–3 thin coats of paint (allow 30 minutes drying time between coats).- Use an airbrush for large surfaces (Z.B., a plush toy’s body) or a fine-tip brush for details (Z.B., eyes). |

Perspektive der Yigu -Technologie
Bei Yigu Technology, we see choosing the right toy prototype processing method as a “cost-time-quality balance act.” Too many clients overspend on CNC machining for simple toys or rely on 3D printing for large batches—wasting time and money. Unser Ansatz: We analyze toy complexity (Z.B., “Does it have moving parts?”) and batch size to recommend the best method. Zum Beispiel, we helped a toy startup cut costs by 40% by switching from 3D printing 50 doll prototypes to silicone molding (using a 3D-printed master). Auch die Sicherheit steht bei uns an erster Stelle: Wir stellen sicher, dass bei der Nachbearbeitung alle scharfen Kanten entfernt werden und verwenden ungiftige Farben für Kinderspielzeug. Für Spielzeugentwickler, Bei der richtigen Methode geht es nicht nur um die Herstellung eines Prototyps – es geht darum, Designs effizient zu validieren und gleichzeitig die Sicherheit von Kindern zu gewährleisten.
FAQ
- Kann ich mehrere Verarbeitungsmethoden für einen einzelnen Spielzeugprototyp kombinieren??
Ja – hybride Ansätze sind weit verbreitet. Zum Beispiel: 3D Drucken Sie den komplexen Kopf eines Spielzeugs (mit Gesichtsdetails), CNC-Bearbeitung seines starren Körpers (für Haltbarkeit), und fertigt seine Kleidung aus weichem Stoff in Handarbeit an. Dies gleicht Präzision aus, kosten, und Anpassung.
- What’s the most cost-effective method for 10–15 units of a detailed toy (Z.B., a doll with painted features)?
Silicone molding is best. Make a single 3D-printed resin master (captures painted details via texture), then produce 10–15 PU resin copies. Total cost is 30–50% lower than 3D printing each unit separately.
- How do I ensure a CNC-machined toy part meets safety standards (Z.B., keine scharfen Kanten)?
- Design parts with ≥0.5mm edge radii in the 3D model (avoids sharp corners during machining).
- Post-process with a deburring tool to remove burrs, then sand edges with 400+ Schleifpapier.
- Test edges with a “choking hazard tester” and a soft cloth (no snags or sharp points).
