5. Часто задаваемые вопросы: Common Questions About 3D Printing Device Models
1 квартал: Are 3D printing device models capable of printing functional parts?
Yes—depending on the technology. SLS models (using metal or nylon powder) can print functional parts (НАПРИМЕР., Небольшие шестерни) with strength similar to full-size SLS printers. FDM models are better for non-load-bearing parts (НАПРИМЕР., прототипы), while SLA models excel at high-detail, Неструктурные детали (НАПРИМЕР., dental molds).
2 квартал: How much do 3D printing device models cost compared to full-size printers?
FDM educational models cost \(200- )1,000 (против. \(1,000- )5,000 for full-size FDM printers). Industrial SLA/SLS models range from \(5,000- )20,000 (против. \(20,000- )100,000+ for full-size industrial printers)—a 50–75% cost reduction.
Q3: Can virtual 3D printing device models replace physical ones?
Virtual models (симуляции) are great for testing software or process parameters (НАПРИМЕР., скорость печати, высота слоя) without material waste. Однако, physical models are necessary for hands-on learning, Материальное тестирование, and validating part feel/function—so they complement rather than replace each other.
