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.
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.
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 long can you leave resin in the 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.
Can you leave resin in the vat?
You can leave resin in your 3D printer’s tank or vat between prints and things should be just fine. It’s a good idea to use the plastic scraper that comes with your resin 3D printer to move the resin around and detach any hardened resin before printing another model.
How long should I cure my resin prints?
Generally, a 3D resin print, will take 1-5 minutes to cure, if being cured under a UV lamp. If your 3D print is a miniature, it will be around 1 minute to cure. But if it is a little larger, and more averagely sized, it can be around 3-5 minutes to fully cure.
Is FEP Teflon?
Fluorinated ethylene propylene was invented by DuPont and is sold under the brandname Teflon FEP. FEP and PFA both share PTFE’s useful properties of low friction and non-reactivity, but are more easily formable. FEP is softer than PTFE and melts at 260 °C; it is highly transparent and resistant to sunlight.
Can you laser cut FEP?
We can help you with laser cut FEP sheets at any quantity. We only sell high quality European Dupont – Teflon FEP film with high transmittance and strength.
How do you remove cured resin from an LCD screen?
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.
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.
Is PTFE a good lubricant?
Anti-Friction Dry PTFE Lubricant is a great lubricating spray for a number of scenarios and environments.
Why are my Resin prints sticky?
Left-Behind Resin Makes Sticky Prints If enough uncured (or partly-cured) resin is left behind after part washing, it contaminates a print’s surface and makes it sticky. This happens in one or both of the following ways: The IPA used to wash parts is dirty. The alcohol evaporates, and the resin is left behind.
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 do you remove resin from FEP?
The resin will harden, making it harder to clean the FEP film, which could reduce its overall lifespan. After printing, gently use a soft scraper to scrape cured resin off the FEP film. If this doesn’t work, use your fingertip to push the bottom of the FEP film, like the GIF down below.
Why do my Resin prints keep failing?
There are many reasons that can cause the resin 3D prints to fail halfway. It can be caused because of the wrong exposure time, unbalanced build platform, not enough support, bad adhesion, wrong part orientation, and many more. Resin is Contaminated. LCD Optical Screen is Too Dirty.
Why are my Resin prints not sticking to the build plate?
The slant raft or bottom may cause the failures for the generation of supports. Then the print job fails. Besides, if the distance between the screen and the build plate is too huge, your print won’t stick properly to the build plate. If printed too fast, the first layer do not have time to bond to the build plate.
Why is my resin 3D print not sticking to the bed?
If your 3D print is not sticking to the bed, check the distance between the bedplate and the nozzle. If the nozzle is too close to the bed, then the filament will not be able to come out, or the extruder could damage or drag the previously printed layer.
