Discover the unique properties, applications, pros, and cons of resin and filament in this ultimate guide.
Introduction
This article aims to provide a comprehensive comparison of resin and filament 3D printing materials, highlighting their strengths and weaknesses.
By understanding the differences between these materials, you can make an informed decision about which is best suited for your specific 3D printing project.
Understanding Resin vs Filament
3D Printing Resin
Resin is a liquid polymer material used in 3D printing processes like Stereolithography (SLA) and Digital Light Processing (DLP). In these methods, a laser or projector cures the resin layer by layer, solidifying the 3D model.
Resins are categorized based on their properties and applications:
Standard resins
General-purpose resins for creating detailed models and prototypes.
Examples include:
Clear resins: Ideal for showcasing internal features or creating molds for casting.
Gray resins: Offer a neutral base for painting and post-processing applications.
Flexible resins
Offer elasticity and durability, suitable for flexible parts and prototypes.
Castable resins
Designed for investment casting, allowing for metal replicas of 3D models. Examples include:
Lost wax casting resins: Burn out cleanly without leaving residue, ideal for creating jewelry or detailed metal parts.
Investment casting resins: Specifically formulated for various metals like silver or bronze, ensuring successful casting processes.
Biocompatible resins
Approved for use in medical applications, ensuring safety for dental models or surgical guides. Examples include Denture resins.
Resin 3D printing excels in producing highly detailed, smooth, and accurate parts. It's ideal for creating complex geometries, jewelry, dental models, and miniatures requiring precise dimensions.
3D Printing Filament
Filament is a thermoplastic material extruded layer by layer in Fused Deposition Modeling (FDM) or Fused Filament Fabrication (FFF) 3D printing. A heated nozzle melts the filament, depositing it onto the build platform to create the 3D object.
Common filament types include:
PLA (Polylactic Acid): Biodegradable and easy to print, suitable for prototypes and general-purpose objects.
ABS (Acrylonitrile Butadiene Styrene): Strong and durable, often used for functional parts and engineering applications. Examples include:
ABS blends: Combine the strength of ABS with other materials like fire retardant additives for specific applications.
High-impact ABS: Offers increased impact resistance for parts that may experience wear and tear.
PETG (Polyethylene Terephthalate Glycol: Tough, impact-resistant, and offers good clarity, suitable for various applications.
TPU (Thermoplastic Polyurethane): Flexible and elastic, ideal for creating rubber-like parts and prototypes.
Filament 3D printing is versatile and cost-effective, making it popular for prototyping, functional parts, hobby projects, and educational purposes. It offers a wider range of materials with varying properties and is generally easier to use compared to resin printing.
