3D printer films such as ACF and FEP are used in the printing process of photopolymer 3D printers. Here are the main differences between them:
1. Material:
- FEP (Fluorinated Ethylene Propylene) : This is a fluoroplastic film that has high chemical resistance and excellent transparency. It is commonly used in most 3D printers and is well suited for printing with photopolymers.
- ACF (Adhesive Coated Film) : This is a film with an adhesive coating that improves the adhesion of layers to the film, which can reduce printing errors and improve quality. ACF can be made from a variety of materials, including polyethylene and other polymers.
2. Transparency:
- FEP : Provides excellent transparency, allowing UV light rays to pass through the film without loss.
- ACF : May have less transparency than FEP, depending on the type and quality of material used.
3. Adhesion:
- FEP : May require the use of additional adhesion enhancers as some photopolymers may not adhere well to this film.
- ACF : Has better adhesion to most photopolymers, which reduces the likelihood of delamination and improves print quality.
4. Service life:
- FEP : May have a longer lifespan as it is resistant to chemicals and UV rays.
- ACF : Service life may vary depending on the material used and operating conditions.
5. Cost:
- FEP : Generally more affordable and widely used in industry.
- ACF : May be more expensive due to additional features such as improved adhesion.
The choice between ACF and FEP depends on your printing needs, the type of photopolymers used, and the desired quality of the finished product. If you need more control over adhesion, ACF may be the better choice. If high transparency and durability are important, FEP may be a better choice.
