If you’re using light curing 3D printing (НАПРИМЕР., СЛА, DLP technologies) для прототипов, функциональные части, 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 к 10 RMB/gram for high-end, Медицинские детали. This guide breaks down the core cost drivers, provides practical references, shares cost-saving tips, and answers common questions to help you make informed decisions.
1. 5 Core Components of Light Curing 3D Printing Cost Per Gram
Стоимость светоотверждаемой 3D-печати за грамм представляет собой сумму материальных составляющих., от сырья до труда. Ниже приведена подробная разбивка с реальными цифрами, иллюстрирующая вклад каждой части.:
(1) Resin Material Cost (The Largest Driver)
Тип смолы напрямую влияет на базовую стоимость: обычные смолы доступны по цене., в то время как специализированные варианты (НАПРИМЕР., стоматологический, высокотемпературная) командные премии.
| Категория смолы | Стоимость за грамм (юаней/грамм) | Ключевые характеристики | Типичные приложения |
| Обычная смола | 0.02 ~ 0.05 | Бюджетный, основная деталь; подходит для простых прототипов | Модели для хобби, нефункциональные части дисплея |
| Высокоэффективная смола | 0.05 ~ 0.2 | Теплостойкий (до 120 ° C.), инженерный уровень (Абс, Герцоги) | Функциональные части (НАПРИМЕР., Небольшие шестерни, Электронные корпуса) |
| Специальная функциональная смола | ≥ 0.2 | Биосовместимый, проводящий, или флуоресцентный; соответствует отраслевым сертификатам | Стоматологические модели, Медицинские компоненты, кондуктивные датчики |
Пример: 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) Амортизация оборудования & Energy Consumption
Light curing printers are more expensive than basic FDM machines, and their depreciation plus energy use adds to the per-gram cost.
| Тип стоимости | Стоимость за грамм (юаней/грамм) | Ключевые детали |
| Амортизация оборудования | 0.05 ~ 0.2 | Industrial-grade SLA/DLP printers cost 10,000–1,000,000 RMB; depreciation is spread over 5–10 years |
| Energy Consumption | 0.01 ~ 0.05 | High-power UV light sources (30–100W) drive energy use; higher for large-format printers |
Ключевая нота: 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) Post-Processing Costs
Nearly all light curing parts need post-processing—cleaning, выклятый, and finishing—which adds 0.1–1.2 RMB/gram depending on complexity.
| Поступ-обработка шага | Стоимость за грамм (юаней/грамм) | Цель |
| Уборка (Isopropyl Alcohol) | 0.05 ~ 0.2 | Remove uncured resin from the part surface |
| Вторичное отверждение (UV/Oven) | 0.05 ~ 0.2 | Improve part strength and durability |
| Шлифование/полировка | 0.1 ~ 0.5 | Smooth surface roughness (Ra from 1μm to <0.5мкм) |
| Распыление/покрытие | 0.1 ~ 1.0 | Add protection (НАПРИМЕР., Сопротивление царапин) or aesthetic effects (НАПРИМЕР., матовая отделка) |
Пример: 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) Труд & Service Fees
If you outsource to a service provider, труд (программирование, операция, качественные проверки) can account for 50%+ of the total cost—especially for small batches or complex parts.
| Service Scenario | Стоимость за грамм (юаней/грамм) | Key Inclusions |
| Basic Service (Simple Parts) | 0.5 ~ 2.0 | 3D Печать + basic post-processing (cleaning/curing) |
| Premium Service (Complex/High-Precision Parts) | 2.0 ~ 5.0 | Custom programming + fine post-processing (sanding/polishing) + качественная проверка |
Пример: 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) Стоимость отходов материалов
Light curing requires support structures, which increase resin use by 20–50%. Этот “waste cost” adds 0.004–0.1 RMB/gram to the total.
| Support Structure Density | Waste Rate | Added Cost Per Gram (юаней/грамм) | Пример (100g Part) |
| Низкий (Simple Parts) | 20 ~ 30% | 0.004 ~ 0.03 | 20–30g extra resin → 0.4–3 RMB added |
| Высокий (Сложные части) | 30 ~ 50% | 0.006 ~ 0.1 | 30–50g extra resin → 0.6–10 RMB added |
2. Общая стоимость светоотверждаемой 3D-печати за грамм: Разбивка по сценариям
To see how these components add up, below are three common scenarios—from low-cost prototypes to high-end specialized parts:
| Сценарий | Resin Cost (юаней/грамм) | Equipment/Energy (юаней/грамм) | Пост-обработка (юаней/грамм) | Labor/Service (юаней/грамм) | Total Cost Per Gram (юаней/грамм) | Пример (100g Part Total Cost) |
| Low-Cost Prototype (Обычная смола + 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 юаней |
| Mid-Range Functional Part (Высокоэффективная смола + 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 юаней |
| High-End Specialized Part (Special Resin + Сложная пост-обработка) | ≥ 0.2 | 0.1 ~ 0.2 | 0.3 ~ 1.2 | 2.0 ~ 5.0 | 2.0 ~ 10.0 | 200 ~ 1,000 юаней |
3. 4 Проверенные советы по снижению затрат на грамм светоотверждаемой 3D-печати
You don’t have to compromise on quality to lower costs. Try these strategies:
(1) Выберите подходящую смолу для ваших нужд
- 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 (НАПРИМЕР., heat resistance for engine components, biocompatibility for dental models).
(2) Оптимизация вспомогательных структур для сокращения отходов
- Используйте программное обеспечение (НАПРИМЕР., Весна, Lychee Slicer) to generate minimal but effective supports—cut waste rate from 50% к 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) Пакетная печать для снижения затрат на рабочую силу и обслуживание
- Group small parts into a single print job—service providers often offer 20–40% discounts for batches of 10+ части, 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) Пропустить ненужную пост-обработку
- For non-visible parts, skip sanding/polishing—save 0.1–0.5 RMB/gram.
- Avoid expensive coatings unless the part needs extra protection (НАПРИМЕР., на открытом воздухе). Basic secondary curing is often sufficient for most indoor parts.
4. Ключевые меры предосторожности, позволяющие избежать неожиданных затрат
- 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 (Могил): Service providers often have MOQs (НАПРИМЕР., 50g or 10 части). Smaller orders may have a “minimum fee” (50–200 RMB) that inflates the per-gram cost.
- Compare Technologies for Simple Parts: If accuracy/surface quality isn’t critical, ФДМ-печать (0.1 юаней/грамм) is cheaper than light curing (0.1–0.5 RMB/gram) for basic prototypes.
Взгляд Yigu Technology на стоимость грамма светоотверждаемой 3D-печати
В Yigu Technology, Мы верим balancing cost and performance is key to maximizing value from light curing 3D printing. Many clients overspend by using special resin for simple prototypes or over-processing non-critical parts—for example, using dental resin (≥0.2 RMB/gram) for a display model when ordinary resin (0.02–0.05 RMB/gram) Работа. Our team helps optimize costs: we recommend desktop printers (lower depreciation) for small-batch in-house use, design support structures to cut waste by 20–30%, and offer batch discounts for service clients (20–40% off for 10+ части). For high-end needs, we prioritize cost-effective steps—e.g., using sanding instead of expensive coatings—to keep per-gram costs 10–15% lower than industry averages. Our goal is to make light curing accessible without sacrificing quality.
Часто задаваемые вопросы
- Why is light curing 3D printing more expensive per gram than FDM?
Light curing uses more costly materials (смола против. PLA/ABS filaments) и требует специализированного оборудования (UV light sources) with higher depreciation. Пост-обработка (уборка, secondary curing) is also mandatory for light curing, adding costs that FDM often avoids. Например, 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?
Материальные отходы (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% напрасно тратить, you need 150g of resin—raising material costs by 50%. Optimizing supports can cut this waste to 20%, снижение затрат на материалы 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). Например, printing 1kg of parts in-house costs 100–500 RMB vs. 500–5,000 RMB from a service—saving 80–90% for large volumes.
