Is resin or filament better for 3d printing [+ Comparison Chart]
Compare resin and filament 3D printing in this complete guide. Learn which material suits your project, and access Autofabx’s free material selection tool and datasheets to choose with confidence.
Introduction
Selecting the appropriate material for 3D printing is crucial for achieving optimal results in your projects. The two primary materials used are filament and resin, each offering distinct advantages and considerations. This comprehensive guide aims to provide an in-depth comparison to assist you in making an informed decision.Understanding Filament and Resin 3D Printing
Filament 3D Printing (Fused Deposition Modeling - FDM):
This method involves melting thermoplastic filaments and extruding them layer by layer to build an object. It's widely recognized for its versatility and cost-effectiveness.
Resin 3D Printing (Stereolithography - SLA / Digital Light Processing - DLP):
This technique uses a light source to cure liquid photopolymer resin into solid parts, layer by layer. It's renowned for producing high-resolution prints with smooth surface finishes.
What’s the Difference Between Resin and Filament Printing?
The core difference lies in technology and application. Resin printing offers higher detail and smoother finishes, while filament printing is known for strength, cost-efficiency, and ease of use.
Detailed Comparison
Aspect | Filament Printing (FDM) | Resin Printing (SLA/DLP) |
|---|---|---|
Print Quality & Detail | Moderate resolution; visible layer lines; suitable for larger, less detailed objects. | High resolution; smooth surfaces with fine details; ideal for intricate designs. |
Strength & Durability | Generally strong; suitable for functional parts and prototypes. | Can be brittle; best for detailed models not subjected to mechanical stress. |
Build Volume | Larger build volumes; capable of printing sizable objects. | Smaller build volumes; better suited for small to medium-sized objects. |
Material Costs | Lower material costs; filaments are more affordable. | Higher material costs; resins are more expensive. |
Post-Processing | Minimal; may require support removal and surface smoothing. | More involved; includes washing, curing, and handling of uncured resin. |
Safety & Handling | Safer; fewer hazardous materials; minimal ventilation requirements. | Requires careful handling; resins can be toxic; necessitates proper ventilation and protective equipment. |
Environmental Impact | Filaments like PLA are biodegradable; less waste produced. | Resins are less environmentally friendly; disposal requires special considerations. |
Which Material is Better for Your Project?
This depends on your specific application:
If your project requires fine details, smooth finishes, or small-scale precision parts (e.g., dental models, figurines, or molds): Resin is typically better.
If you need stronger, durable, and functional parts (e.g., enclosures, jigs, fixtures, or mechanical components): Filament is a better choice.
Applications
Filament Printing Example: The black custom tray in the image above was printed using FDM technology. It's a durable, practical part designed to organize and protect components during transport. This example highlights filament printing's strength and cost-effectiveness, particularly for industrial and functional parts.
