What is a 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.
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.
When should I replace my FEP?
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.
What thickness is FEP film?
The film that the Photon ships with is 0.015mm thick.
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).
What type of plastic is FEP?
FEP (fluorinated ethylene propylene) is a tough, flexible copolymer of tetrafluoroethylene and hexafluoropropylene. It is often used for flexible tubing and fluid processing equipment when chemical resistance, high purity, and low stiffness are required. FEP has outstanding electrical properties and UV resistance.
What is the difference between FEP and PTFE?
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.
What is the FEP on a 3D printer?
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.
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.
Can you cut FEP film?
Cut away the excess FEP film with a box cutter. Hold the edges of the excess FEP film in one hand and use a box cutter to slice them off. Cut the film as close to the metal pieces as you can so that nothing is sticking out.
How do you clean the screen on a resin printer?
Please apply a small amount of 95% sanitizing alcohol on the printer’s LCD screen to remove any cured resin, smudges, and/or fingerprints present on the LCD screen. Use a paper towel or a fiber cloth and wipe in one direction to thoroughly clean the surface of the LCD screen.
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 FEP oil resistant?
It is the user’s responsibility to evaluate and fully test the suitability of the product for their specific application.Chart codes. Chemical Oils, essential R Resistance R R.
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 FEP cable used for?
FEP is the compound of choice for high-temperature plenum environments and can be found in Galaxy’s Belden equivalent cable offerings. Another common use for FEP is as an insulation and filler material in TEC cable, used in the oil and gas industry.
Is FEP Teflon?
Fluorinated ethylene propylene (FEP) shares some of the same non-stick qualities of Teflon though its structure is slightly different. FEP is softer and therefore melts at a lower temperature than PTFE. This means it is less commonly used in cooking and baking.
What is FEP tubing?
FEP (Fluorinated Ethylene Propylene) is a semi-clear tubing product that maintains its strength and benefits in a wide range of temperatures and conditions. FEP tubing is designed with enhanced chemical resistance with advanced gas and vapor permeability properties and excellent UV transmission ratings.
Which is better PFA or PTFE?
PFA is superior to PTFE in terms of flexibility particularly when it comes to tubing applications. PTFE is slightly more resistant to heat than PFA. PFA is more affected by water absorption and weathering but is superior to PTFE when it comes to salt spray resistance.
Is PTFE a PFA?
PFA, or Perfluoroalkoxy, is a type of fluoropolymer. It has very similar properties as the more common polytetrafluoroethylene (PTFE), which is the more popularly known form of Teflon. PFA was conceived by DuPont Co. and given the brand name Teflon PFA.
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.
