Question: What Is Fep Film

The FEP film is the double-layered and transparent foil installed in the rack attached to the resin tank. It creates a clean way for the UV light to cure liquid resin during the whole printing process. Otherwise, the printer will not produce successful prints.

What is FEP film made of?

Norton® FEP fluoropolymer film is manufactured from flourinated ethylene propylene (FEP) resin by Saint Gobain Advanced films and Fabrics in four grades.

What is a FEP in 3D printing?

Material. FEP is a fully fluorinated polymer, a family of plastics well known for its anti-stick properties. FEP is an extrudable material and brings the properties of fluor-polymers to 3D printers. Apart from the anti-stick properties, it has a low coefficient of friction and very high weathering and UV stability.

What is FEP release film?

FEP Type RF, release film, is a clear or pigmented film manufactured from fluorinated ethylene propylene resin. High elongation and a smooth, low-gel film surface allow FEP to conform to complex mold contours and produce a smooth part finish. Perforated film is available to control out gassing and resin bleed.

What is FEP sheet?

FEP (fluorinated ethylene propylene) is a copolymer often used when chemical resistance, high purity, and low stiffness are required. FEP has outstanding electrical properties and UV resistance. FEP FDA compliant grade is available.

What can I use instead of FEP?

Laminating pouches are an alternative to FEP film on resin 3D printers. They do need preparation such as putting it in the oven to dissolve the EVA on one side for just 5 seconds. Once you’ve done this, put the PET side facing upwards in your resin vat and that should be done.

Is FEP waterproof?

Other brandnames are Neoflon FEP from Daikin or Dyneon FEP from Dyneon/3M. FEP is very similar in composition to the fluoropolymers PTFE (polytetrafluoroethylene) and PFA (perfluoroalkoxy polymer resin). FEP Maximum operating temperature 204 °C Water absorption (ASTM) <0.01 % after 24 hours Dielectric constant (Dk).

When should you change your FEP film?

FEP films should be replaced when they have major signs of wear and tear such as deep scratches, punctures, and regularly result in failed prints. Some can get at least 20-30 prints, though with proper care, FEP sheets can last several prints without damage.

How do you clean FEP film?

Ensure you are wearing gloves, disconnect your resin tank from the 3D printer and pour left over resin back into the bottle with a filter on top, scrape any hardened resin too. Gently dab some paper towels to clean any leftover resin. Use isopropyl alcohol to clean the resin vat and FEP film.

What thickness is FEP film?

The film that the Photon ships with is 0.015mm thick.

What does FEP stand for?

FEP Acronym Definition FEP Federal Employee Program FEP Front End Processor FEP Fluorinated Ethylene Propylene FEP Fraunhofer-Institut für Elektronenstrahl-und Plasmatechnik (German: Fraunhofer Institute for Electron Beam and Plasma Technology).

How do you replace FEP Phrozen?

Step 1: Spray some Phrozen Wash or 95% sanitizing alcohol, IPA, on the FEP film frame, and clean it with a paper towel or a fiber cloth. Step 2: Place the FEP film between the resin vat and the FEP film frame. Step 3: Slightly tighten the screws in the corners first. Then continue onto the sides.

What does FEP stand for resin printer?

3d printing FEP (Fluorinated Ethylene propylene).

Is FEP flame retardant?

Optimizing flame retardant loading is a challenge for compounders.Reduce Flame retardant loading in compounds. Product Fluoropolymer Fluoropolymer films Fluoro coatings Polymer additives PFA, FEP, CPT, PCTFE Properties Flammability UL-94 V-0 limit oxgen concentration (vol%) >95.

Is FEP flammable?

Among fluoropolymers, FEP has many favorable mechanical attributes including comparable tensile strength to PTFE and a comparatively low coefficient of friction. temperatures of 260 °C (500 °F) and 204 °C (400 °F), respectively. In this same vein, FEP has high heat performance, and it is UL 94-0 rated for flammability.

What is the difference between FEP and Teflon?

PTFE and FEP are similar in their material properties. The main difference between PTFE and FEP lies in the maximum operating temperature and the colour. PTFE is milky/white and FEP is clear transparent.

How do I cut in a photon workshop?

Click on the “Slice” button (bottom icon on the left). A dialog box should pop up where you can save your sliced model file. Select a location on your computer (or USB) and click the “Save” button. Another dialog box called “Slicing to Photon…” should appear, displaying the progress of the slicing.

Does IPA damage FEP?

The recommend use of warm water and disc-wash soap is a little messy. As I understand it, FEP is chemical resistant like PTFE (Teflon) and should not be damaged by alcohol (IPA). Other SLA printer manufacturers suggest using IPA/Alcohol for cleaning their FEP films.

How do you keep resin from sticking to FEP?

To stop your resin 3D prints sticking to the FEP, you should make sure you have enough bottom layers and bottom layer curing time, so it has enough time to harden. Use PTFE spray on your FEP film, let it dry, and this should create a lubricant to stop the resin from sticking to the resin tank.

How long does resin stay in vat?

Uncured resin can remain intact in the tank or vat of your 3D printer for many weeks if you keep it away from UV light exposure. The ideal condition for storing uncured resin is a cool, dark place. If the environment is not ideal, the UV resin may last for as short as a few hours or 1-2 days.

Does FEP thickness matter?

Very even thickness so less chance off distortion. Because it is a little thicker, less chance on rippling and it should last longer. If you want to be sure your highly detailed print or jewelery prints comes out perfect.

Is PTFE a wd40?

WD-40 Specialist® Dry Lube 10 oz. WD-40 Specialist® Dry Lube with PTFE is a dry lubricant that keeps your equipment running smoothly with long-lasting corrosion protection that does not attract dirt, dust, or oil.

Why do prints stick to the FEP?

But if the Fep is worn or too loose or too tight, it may affect the peel force, resulting in the sticking problem. The editing of the part itself, such as improper placement of the angle, hollowing, punching, etc. may result in excessive peel force/separation force, which may also lead to sticking.

Is PTFE a good lubricant?

Anti-Friction Dry PTFE Lubricant is a great lubricating spray for a number of scenarios and environments.
