How long does the resin tray last?
The resin tray lifespan depends on operating frequency and total usage time.
In most cases, the resin tray maintains optimal print quality for up to 1,500 hours or 6 months, whichever comes first.
Without accidental damage, good print performance is expected to last 3,000–6,000 hours or 1–2 years, whichever comes first.
To extend the resin tray lifespan, establish a maintenance schedule — thoroughly and carefully clean the tray every 2 to 4 weeks to achieve its ideal expected service life.
When should I turn the oxygen generator on or off?
When the printer is idle, you may turn off the oxygen generator to reduce wear.
Before starting a print, allow at least 5–10 minutes for the oxygen generator to stabilize at the proper flow rate and oxygen concentration. Once ready, verify steady airflow via the flow meter on the machine.
Cophoda casting-pattern 3D printers require an oxygen generator during operation. It forms a thin oxygen layer on the oxygen-permeable film, accelerating the printing process and reducing separation suction — resulting in shorter print times and better print quality.
How long can resin sit in the tray? How do I clean the resin tray?
We recommend giving the resin tray a rest period over weekends and holidays.
If resin remains in the tray, stir and mix it with a silicone spatula before morning operation. If the printer will be idle for several days, drain and filter the resin to protect it from light exposure, dust, and foreign particles.
After draining and filtering, store the filtered resin in a separate bottle to avoid cross-contamination with unused resin and to shield it from dust and debris near the machine. When draining, gently scrape off all resin with a silicone spatula to minimize waste.
What tool should I use to filter the resin?
A filter paper funnel is included with every resin purchase. Keep filtered and unfiltered resin separate to prevent cross-contamination.
How do I choose a cleaning solution?
We recommend preparing 2–3 beakers and high-purity alcohol or IPA (99%+) for subsequent use with an ultrasonic cleaner.
Debris on the resin tray is difficult to clean
Important: aside from lint-free wipes, silicone spatulas, and gloves, never allow sharp or hard objects to contact the resin tray film. If you encounter difficulty cleaning debris, drain the resin first before proceeding.
This can be tedious and requires care. Clean promptly whenever possible to reduce later cleaning difficulty.
Note: accidental damage to the resin tray is not covered under warranty.
English FAQ
How long is the lifespan of the Resin Vat?
The lifespan of the resin vat depends on the frequency of equipment operation and total usage time.
In most cases, the vat remains in "perfect printing condition" for up to 1,500 hours or 6 months, whichever comes first.
Provided there is no manual damage, the expected "good printing condition" lasts between 3,000–6,000 hours or 1–2 years, whichever comes first.
To maximize the vat's lifespan, please establish a maintenance plan to thoroughly and carefully clean the resin vat every 2 to 4 weeks.
When should I turn the Oxygen Generator on or off?
If the equipment is not actively printing, you may turn off the oxygen generator to reduce wear and tear.
When preparing to print, the oxygen generator requires at least 5–10 minutes of stabilization time to produce the ideal flow rate and oxygen concentration.
Once stabilized, confirm the flow via the airflow meter on the device.
The Cophoda White Wax machine must use the oxygen generator during operation. Oxygen forms a thin "dead zone" layer on the oxygen-permeable membrane, which accelerates the printing process and reduces separation suction (pull force), thereby improving print speed and quality.
How long can material stay in the Resin vat? How do I clean it?
It is recommended to give the resin vat a "rest and breathing period" during weekends and holidays by emptying it.
If material is left in the vat overnight, use a silicone scraper to stir and mix the resin thoroughly before running the machine in the morning.
If the device will not be used for several days, it is recommended to pour out and filter the material to prevent exposure to light or contamination from dust and foreign objects.
After filtering, store the used material in a separate bottle to avoid cross-contaminating unused resin.
When emptying the vat, use a silicone scraper to carefully remove all material to minimize waste.
What tools should be used to filter the material?
A paper filter funnel is included as a gift with your material purchase.
Please ensure that you keep filtered (used) material separate from new material to prevent cross-contamination.
How do I choose a cleaning agent?
We recommend preparing 2–3 beakers and using high-purity alcohol (99% or higher), which is convenient for use with ultrasonic cleaning tools.
What if debris on the Resin vat membrane is difficult to clean?
Reminder: Only use dust-free paper, silicone scrapers, and gloves. Strictly prohibit any sharp or hard objects from contacting the resin vat membrane.
If you encounter difficulties cleaning debris, it is recommended to pour out the resin for easier handling.
Cleaning fine debris can be difficult and requires patience and experience.
Note: The warranty does not cover resin vats that have been damaged by improper manual handling.
