Who it fits
Good fit for
You should buy this if you own an ELEGOO Mars series printer, such as the Mars 2, Mars 3, or their Pro variants. It also fits Photon Mono, Mono 4K, and Sonic Mini 4K models. The 200x140mm size is ideal for users who need a standard replacement film. If you print regularly and want a durable, non-stick surface with high light transmission, this pack offers good value. The included instructions make it easy for beginners to replace their film correctly.
Who should skip it
You should skip this if your printer requires a different film size. This pack only includes the 200x140mm variant. If you use a larger printer like the Elegoo Saturn, you need the 260x200mm or larger options. Also, avoid this if you prefer a thicker film, as this is strictly 0.15mm. Do not buy this for SLA printers that do not use FEP film. Check your printer manual to confirm the required dimensions before purchasing to avoid compatibility issues.

Key specs explained for you
Dimensions: 140 x 200 x 0.15mm
This size matches the build platform of many entry-level resin printers like the Elegoo Mars series. The 0.15mm thickness is the standard for flexible replacement films. You need this exact dimension to fit your printer’s frame without gaps. If your printer uses a different size, this film will not work. Check your manual for the required dimensions before buying.
Release Film Type: FEP
FEP stands for fluorinated ethylene propylene. This material is chosen for its low surface energy and non-stick properties. It allows cured resin to release easily from the bottom of the vat. This reduces the force needed to lift each layer. You get smoother prints with fewer failed builds. This is the standard material for most resin 3D printing release films.
Light transmission: 95%
High light transmission ensures that the UV light from your printer’s LCD screen reaches the resin efficiently. A 95% rate means minimal light loss through the film. This stability helps maintain consistent curing depths. You get more reliable prints with fewer defects. Lower transmission rates can lead to under-cured layers. This spec is crucial for maintaining print quality over time.
Film Thickness: 0.15mm
This specific thickness balances flexibility with durability. Thinner films may tear easily during installation or use. Thicker films can reduce print resolution. The 0.15mm standard is widely supported by resin printer manufacturers. It allows for fine detail reproduction while remaining tough enough for repeated use. You should stick to this thickness for optimal results with your current printer model.
Design and build details
According to the listing, the KOYOFEI film is a clear FEP release sheet. FEP material provides the low-friction, non-stick surface you need for resin printing. This allows cured layers to release cleanly from the build plate. The listing notes excellent non-wettable properties, which helps maintain print quality over time. You get six pieces in this pack, offering ample supply for long-term use.
The dimensions are 140 x 200mm with a thickness of 0.15mm. This size matches the LCD screen area of many entry-level resin printers. The 0.15mm thickness is standard for flexible replacement films. It balances durability with the flexibility required to stretch over the printer frame without tearing. The listing states the film has 95% light transmission. This ensures high stability of UV lighting, which is critical for accurate resin curing.
The listing mentions heat-resistant properties and durable quality. These traits suggest the film can withstand repeated heating cycles during printing. The pack weighs 2.82 ounces and is compact for storage. Instructions are printed on the packaging to guide you through installation. This clear, straightforward design focuses on function. It suits users who need reliable, standard-sized replacement films for their resin printers.
Setup and daily use guide
Setting up the KOYOFEI FEP film is straightforward because the manufacturer includes clear instructions printed directly on the packaging. You do not need to search for a manual or visit a website. The guide explains how to change the film, which simplifies the process for you. This is helpful if you are new to resin printing.
The film dimensions are 140 x 200 x 0.15mm. This size fits many popular resin printers, including the Elegoo Mars, Mars 2, Mars 3, and their Pro versions. It also works with the Photon Mono, Mono 4K, and Sonic Mini 4K models. Check your printer’s build platform size before installing. The 0.15mm thickness is standard for flexible replacement films. It provides the right balance of durability and flexibility.
In daily use, the film offers a low-friction, non-wettable surface. This property helps cured resin layers release cleanly from the build plate. The material has excellent non-stick characteristics, which reduces the chance of parts sticking to the bottom. The listing states the film has heat-resistant properties and durable quality. This suggests it can handle long-term use without degrading quickly.
Light transmission is listed at 95%. This high percentage ensures stable UV lighting during the printing process. Stable light exposure contributes to consistent layer curing. The film is clear, allowing you to monitor the print process visually. You receive six pieces in the pack. This allows for multiple replacements as the film wears over time.
Before You Buy This Film
You need to verify your printer’s build area matches the 200x140mm dimensions. This film fits the Elegoo Mars series and similar models listed. It does not work for larger printers using 260x200mm or bigger sheets. The 0.15mm thickness is standard, but check your current film to ensure compatibility. You should keep a spare roll ready. Resin prints degrade FEP over time, so having extras prevents downtime. The packaging includes instructions for replacement, making swaps easier. You must handle the film carefully to avoid tears during installation. This pack offers six sheets, which is a practical quantity for regular users. Compare this size against other options in the guide. If your printer uses a different format, skip this item. The clear material ensures good light transmission for stable prints. Maintain your printer’s build plate to extend the film’s life. This product suits those who print frequently and need reliable replacements.
