Desventajas
|
1. Fragility : Resin-printed items are relatively fragile and are not suitable for withstanding large forces or as long-term functional parts.
2. Material cost : The price of resin consumables is usually higher than that of filament consumables, and the cost is higher.
3. Post-treatment is complex : it requires post-treatment with specific chemicals to remove support structures and clean parts.
|
1. Surface roughness : The surface layer marks of filament printing are more obvious and rough, and additional polishing and post-processing are required.
2. Environmental sensitivity : Some materials such as ABS may produce irritating odors during printing and require good ventilation.

Usually no specific nozzle and hot bed temperature is required
|
1. PLA : The nozzle temperature is generally between 190-220 ° C, and the hot bed temperature can be set at 50-60 ° C.
2. abdominales : The nozzle temperature is generally between 230-250 ° C, and the hot bed temperature needs to be set at 90-110 ° C to reduce warping.
3. PETG : Nozzle temperature between 230-260 ° C, hot bed temperature between 80-100 ° C.

Introduction to Consumables
- Resin consumables: used for light-curing 3D printing (such as SLA and DLP technologies), with high precision and fine surface detail, suitable for making models and items such as jewelry.
- Filament consumables: used for fused deposition molding (MDF) 3impresión, common materials include PLA, abdominales, PETG, etc., suitable for rapid prototyping and functional testing.
Pros and Cons Comparison
Advantages of resin consumables: smooth surface, alta precisión, able to capture very fine details. Suitable for making fine objects, such as mini dolls, jewelry parts, etc..
Disadvantages of resin consumables: fragile, not suitable for functional parts that can withstand a lot of force or aging. Exposure of resin materials to sunlight will cause the printing effect to weaken over time. The material cost is relatively high, and attention should be paid to the impact on the environment during use.
Filament consumables advantages: good strength, good toughness, high collision resistance, stable durability, help accurate functional testing. A variety of materials, relatively low cost.
Disadvantages of filament consumables: The surface printing layer marks are obvious and rough. Irritating odor may be generated during the printing process, and temperature and humidity need to be controlled, especially for materials such as ABS.
Print Speed and Efficiency
Resin printing: When printing multiple parts, resin printers can keep the time fixed for each layer, and for situations that require a large number of parts, resin is usually faster.
Filament printing: Filament printers can produce individual objects very quickly, but if more objects are added to the print bed, the print time will increase proportionally.
Durability and Strength
Resin parts: Standard resin prints are quite fragile and are generally not suitable for functional parts that can withstand a lot of force or aging.
Filament components: Use thermoplastic materials with known thermoplastic properties, good strength and durability, especially for outdoor use components, materials with higher strength and heat/ultraviolet resistance can be selected.
Volume and Print Speed
Resin Printing: Entry-level resin 3D printers are built to be small and suitable for printing small, fine parts.
Filament printing: Filament printers typically have larger build volumes and are suitable for printing large parts.
Easy to Use and Post-processing
Resin consumables: post-treatment with specific chemicals is required to remove support structures and clean parts, which may increase the complexity of the operation.
Filament consumables: usually easier to handle, support structures are easy to remove, but may require more post-print sanding and finishing work.
Cost Considerations
Resin consumables: Although the cost per kilogram of resin is higher, the amount of resin used may be less due to the smaller build size of resin printers.
Filament consumables: material costs are relatively low, suitable for users with limited budgets.
Conclusión
The choice between resin and filament consumables depends on your specific needs, presupuesto, and the complexity of the printing project. If you pursue high precision and fine appearance details, resin may be a better choice. If you need to print functional parts with certain strength and heat resistance, or have a limited budget, filament consumables may be more suitable for your needs. Understanding the characteristics and requirements of these materials can help you make more appropriate material choices in 3D printing projects.
