If you’re using light curing 3D printing (Z.B., SLA, DLP technologies) Für Prototypen, Funktionsteile, or specialized components, understanding the cost per gram is critical for budgeting. Unlike FDM printing, light curing costs aren’t fixed—they range from 0.1 RMB/gram for basic applications Zu 10 RMB/gram for high-end, medizinische Teile. In diesem Leitfaden werden die wichtigsten Kostentreiber aufgeschlüsselt, bietet praktische Hinweise, gibt Tipps zum Kostensparen, und beantwortet häufig gestellte Fragen, um Ihnen dabei zu helfen, fundierte Entscheidungen zu treffen.
1. 5 Core Components of Light Curing 3D Printing Cost Per Gram
Light curing 3D printing cost per gram is a sum of tangible components, from raw materials to labor. Below is a detailed breakdown with real numbers to illustrate each part’s contribution:
(1) Resin Material Cost (The Largest Driver)
Resin type directly shapes the base cost—ordinary resins are affordable, while specialized options (Z.B., zahnärztlich, Hochtemperatur) command premiums.
| Kategorie „Harz“. | Kosten pro Gramm (RMB/Gramm) | Schlüsselmerkmale | Typische Anwendungen |
| Gewöhnliches Harz | 0.02 ~ 0.05 | Niedrige Kosten, grundlegendes Detail; Geeignet für einfache Prototypen | Hobbymodelle, nicht funktionsfähige Ausstellungsteile |
| Hochleistungsharz | 0.05 ~ 0.2 | Hitzebeständig (bis zu 120 ° C.), Ingenieursqualität (ABS-ähnlich, Herzöge) | Funktionsteile (Z.B., kleine Zahnräder, elektronische Gehäuse) |
| Spezielles Funktionsharz | ≥ 0.2 | Biokompatibel, leitfähig, or fluorescent; erfüllt Branchenzertifizierungen | Zahnmodelle, Medizinische Komponenten, Konduktive Sensoren |
Beispiel: A 200g ordinary resin part costs 4–10 RMB in material alone. The same part made with dental-grade resin costs ≥40 RMB—4–10x more.
(2) Abschreibung der Ausrüstung & Energieverbrauch
Light curing printers are more expensive than basic FDM machines, and their depreciation plus energy use adds to the per-gram cost.
| Kostentyp | Kosten pro Gramm (RMB/Gramm) | Schlüsseldetails |
| Abschreibung der Ausrüstung | 0.05 ~ 0.2 | Industrial-grade SLA/DLP printers cost 10,000–1,000,000 RMB; depreciation is spread over 5–10 years |
| Energieverbrauch | 0.01 ~ 0.05 | High-power UV light sources (30–100W) drive energy use; higher for large-format printers |
Schlüsselnotiz: Small desktop light curing printers (10,000–30,000 RMB) have lower depreciation costs (0.05–0.1 RMB/gram) than industrial machines (0.1–0.2 RMB/gram).
(3) Nachbearbeitungskosten
Nearly all light curing parts need post-processing—cleaning, Heilung, and finishing—which adds 0.1–1.2 RMB/gram depending on complexity.
| Nachbearbeitungsschritt | Kosten pro Gramm (RMB/Gramm) | Zweck |
| Reinigung (Isopropyl Alcohol) | 0.05 ~ 0.2 | Remove uncured resin from the part surface |
| Sekundäre Heilung (UV/Oven) | 0.05 ~ 0.2 | Improve part strength and durability |
| Schleifen/Polieren | 0.1 ~ 0.5 | Smooth surface roughness (Ra from 1μm to <0.5μm) |
| Sprühen/Beschichtung | 0.1 ~ 1.0 | Add protection (Z.B., Kratzerfestigkeit) or aesthetic effects (Z.B., mattes Finish) |
Beispiel: A 100g part needing cleaning + secondary curing costs 10–40 RMB in post-processing. Adding sanding and spraying raises this to 30–190 RMB.
(4) Arbeit & Servicegebühren
If you outsource to a service provider, Arbeit (Programmierung, Betrieb, Qualitätsprüfungen) can account for 50%+ of the total cost—especially for small batches or complex parts.
| Service Scenario | Kosten pro Gramm (RMB/Gramm) | Key Inclusions |
| Basic Service (Simple Parts) | 0.5 ~ 2.0 | 3D Druck + grundlegende Nachbearbeitung (cleaning/curing) |
| Premium Service (Complex/High-Precision Parts) | 2.0 ~ 5.0 | Custom programming + fine post-processing (sanding/polishing) + Qualitätsinspektion |
Beispiel: A 50g simple part from a basic service costs 25–100 RMB. A 50g high-precision part from a premium service costs 100–250 RMB.
(5) Material Waste Cost
Light curing requires support structures, which increase resin use by 20–50%. Das “waste cost” adds 0.004–0.1 RMB/gram to the total.
| Support Structure Density | Waste Rate | Added Cost Per Gram (RMB/Gramm) | Beispiel (100g Part) |
| Niedrig (Simple Parts) | 20 ~ 30% | 0.004 ~ 0.03 | 20–30g extra resin → 0.4–3 RMB added |
| Hoch (Komplexe Teile) | 30 ~ 50% | 0.006 ~ 0.1 | 30–50g extra resin → 0.6–10 RMB added |
2. Total Light Curing 3D Printing Cost Per Gram: Szenariobasierte Aufschlüsselung
To see how these components add up, below are three common scenarios—from low-cost prototypes to high-end specialized parts:
| Szenario | Resin Cost (RMB/Gramm) | Equipment/Energy (RMB/Gramm) | Nachbearbeitung (RMB/Gramm) | Labor/Service (RMB/Gramm) | Gesamtkosten pro Gramm (RMB/Gramm) | Beispiel (100g Part Total Cost) |
| Low-Cost Prototype (Gewöhnliches Harz + Basic Post-Processing) | 0.02 ~ 0.05 | 0.05 ~ 0.1 | 0.1 ~ 0.4 | 0.5 ~ 2.0 | 0.1 ~ 0.5 | 10 ~ 50 RMB |
| Mid-Range Functional Part (Hochleistungsharz + Standard Post-Processing) | 0.05 ~ 0.2 | 0.05 ~ 0.15 | 0.2 ~ 0.7 | 0.8 ~ 3.0 | 0.5 ~ 2.0 | 50 ~ 200 RMB |
| High-End Specialized Part (Special Resin + Complex Post-Processing) | ≥ 0.2 | 0.1 ~ 0.2 | 0.3 ~ 1.2 | 2.0 ~ 5.0 | 2.0 ~ 10.0 | 200 ~ 1,000 RMB |
3. 4 Proven Tips to Reduce Light Curing 3D Printing Cost Per Gram
You don’t have to compromise on quality to lower costs. Probieren Sie diese Strategien aus:
(1) Wählen Sie das richtige Harz für Ihre Bedürfnisse
- Use ordinary resin for non-functional prototypes (saves 75–90% vs. special resin).
- Reserve high-performance/special resin for parts that need their unique properties (Z.B., heat resistance for engine components, biocompatibility for dental models).
(2) Optimize Support Structures to Reduce Waste
- Verwenden Sie Software (Z.B., Eine Frühling, Lychee Slicer) to generate minimal but effective supports—cut waste rate from 50% Zu 20%, saving 0.03–0.07 RMB/gram.
- Design self-supporting angles (≥45° for most resins) to eliminate the need for supports in some areas.
(3) Batch Print to Lower Labor/Service Fees
- Group small parts into a single print job—service providers often offer 20–40% discounts for batches of 10+ Teile, reducing labor cost per gram by 0.5–1.5 RMB.
- For in-house printing, batch jobs reduce setup time, lowering equipment depreciation and labor costs.
(4) Überspringen Sie unnötige Nachbearbeitung
- Für nicht sichtbare Teile, skip sanding/polishing—save 0.1–0.5 RMB/gram.
- Avoid expensive coatings unless the part needs extra protection (Z.B., Nutzung im Freien). Basic secondary curing is often sufficient for most indoor parts.
4. Key Precautions to Avoid Unexpected Costs
- Account for Material Waste: Always calculate 20–50% extra resin for supports—underestimating this can add 10–30% to the total cost.
- Check Minimum Order Quantities (Mindestbestellmenge): Service providers often have MOQs (Z.B., 50g or 10 Teile). Smaller orders may have a “minimum fee” (50–200 RMB) Das erhöht die Kosten pro Gramm.
- Vergleichen Sie Technologien für einfache Teile: Wenn Genauigkeit/Oberflächenqualität nicht kritisch ist, FDM-Druck (0.1 RMB/Gramm) ist günstiger als Lichthärtung (0.1–0,5 RMB/Gramm) für grundlegende Prototypen.

FAQ
- Why is light curing 3D printing more expensive per gram than FDM?
Light curing uses more costly materials (Harz vs. PLA/ABS filaments) und erfordert spezielle Geräte (UV light sources) with higher depreciation. Nachbearbeitung (Reinigung, secondary curing) is also mandatory for light curing, adding costs that FDM often avoids. Zum Beispiel, FDM PLA costs ~0.1 RMB/gram, while basic light curing costs 0.1–0.5 RMB/gram.
- How much does material waste affect the total cost per gram?
Materialverschwendung (from supports) adds 20–50% to resin use, increasing the effective material cost by 0.004–0.1 RMB/gram. For a 100g part with 50% Abfall, you need 150g of resin—raising material costs by 50%. Optimizing supports can cut this waste to 20%, Reduzierung der Materialkosten durch 30%.
- Can I reduce labor costs by doing light curing 3D printing in-house?
Yes—if you print regularly. In-house printing eliminates service provider labor fees (0.5–5 RMB/gram), though you’ll incur upfront equipment costs (10,000–30,000 RMB for desktop machines). Zum Beispiel, printing 1kg of parts in-house costs 100–500 RMB vs. 500–5,000 RMB from a service—saving 80–90% for large volumes.
