For specific details, you can consult your after-sales specialist or call our after-sales hotline for assistance.
You can consult with your after-sales specialist to make an appointment for professional operation training services, or find the tutorial videos you need in the "Resources - Video Gallery - Metal 3D Printers" through the top/bottom bar.
The power supply for a metal 3D printer must meet the following requirements:
1. Leakage protection switch 220V, 64A;
2. Voltage 220V, voltage fluctuation ±10% (please equip with a voltage stabilizer), must be grounded;
3. Frequency 50/60Hz; Rated power 4-4.5KW, operating power 2.5-3.5KW (including cooling system and circulation filtration system);
4. Maximum current consumption 16-20A;
5. High-frequency radiation-emitting devices or devices with interference signals are not allowed around the equipment.
There are several differences between metal 3D printers for printing titanium-related products and those for printing cobalt-chromium alloy products:
1. Different circulation systems: Metal 3D printers capable of printing titanium-related products have an additional external circulation and two oxygen content meters compared to those printing cobalt-chromium alloy products;
2. Special vacuum cleaner required for printing titanium-related products: Different types of powders should not be mixed in the vacuum cleaner;
3. Different printing gas requirements: When printing titanium-related products, argon gas cylinders are required, with a purity requirement of 99.999%, and a maintenance flow rate of 1-2L/min; inflation pressure less than 0.7mpa; maintenance pressure 0.3mpa, oxygen content needs to be lowered further before printing begins;
4. Different printing processes: After each print of titanium-related products, "blowback" is required 3-4 times;
5. Different filter cleaning steps and frequencies: Metal 3D printers for printing titanium-related products need to clean the external filter every month, and the process requires adding water first, with safety protection in place;
6. Different sieving methods: Manual sieving is recommended for titanium-related powder;
7. Different requirements for annealing furnace: When post-processing titanium-related products, the vacuum annealing furnace needs to strictly control the vacuum degree, and the vacuum pump should be kept on at all times. At the same time, different temperature curves should be set according to the printing requirements of different materials to ensure printing effects and material properties;
8. Fire extinguisher configuration: A Class D metal fire extinguisher should be kept next to the equipment, and the recommended model is 2 MFZ/D2 (Sodium chloride dry powder fire extinguisher).
You can consult with your after-sales specialist, or find the tutorial videos you need in the "Resources - Video Gallery - Metal 3D Printers" through the top/bottom bar.
A metal 3D printer that has printed cobalt-chromium alloy products has already been contaminated in its pipeline and should not be directly converted to print titanium-related products.
If you wish to switch a metal 3D printer used for printing cobalt-chromium alloys to one that prints titanium-related products, please contact your after-sales specialist or call our after-sales hotline for payment and upgrade. (If your equipment model is: M-150pro, you can freely switch between cobalt-chromium alloy printing and titanium printing modes)
The power supply requirements depend on the specifications of the annealing furnace. If the annealing furnace power is 4KW, the required current is 20A; if the annealing furnace power is 9KW, the required current is 40A; if the annealing furnace power is 12KW, the required current is 55A.
Generally, vacuum extraction is sufficient. If high vacuum requirements are needed, protective gas (only nitrogen or argon) can be introduced.
The air compressor must have sufficient power and flow rate; the gas storage tank must have sufficient capacity; a three-stage filtration cold dryer must be equipped to ensure the gas is oil-free and moisture-free.
Air Compressor:
1. Power: For the entire factory: 10kw; Only for the nitrogen generator: 7.5kw
2. Pressure value: 0.7-0.8 mpa
3. Flow rate requirement: At least 0.4 m³/min
Gas Storage Tank:
1. Storage requirement: 0.3 m³/min, 8 kg
2. Capacity: 300L
3. Working pressure: 0.8 mpa
Purified or distilled water free of impurities and ions.
It is conventional to replace the water every half a year to a year. In areas with high temperatures, it is recommended to replace it every three months. Water should be added when the level is below the minimum line. Purified or distilled water free of impurities and ions should be used.
When the indoor temperature is 15℃-20℃, the maximum humidity is 80%;
when the indoor temperature is 20℃-25℃, the maximum humidity is 60%;
when the indoor temperature is 25℃-30℃, the maximum humidity is 45%.
If the indoor temperature is too high, it will cause the water cooler to issue a high-temperature alarm. If the indoor humidity is too high, the metal powder is prone to dampening and clumping, which affects the printing results.
You can check and adjust according to the following list. If the printing deformation problem still occurs after adjustment, you can contact your after-sales specialist or call our after-sales hotline for assistance.

1. Check the printing effect, whether the support is broken or detached during printing, the first layer of powder needs to be a thin layer exposed to the metal surface;
2. Check for deformation, whether the correct support parameters are used. For bridge implants, it is recommended to use a full-cone support and add crossbars and T-bars;
3. If it's not a deformation issue but a hole problem, replicate several identical implants and print them with different compensation values to see which range fits best.
The rough surface of the printed metal dental crown due to powder adhesion may be caused by the following factors. You can check and adjust according to the following list. If the problem still occurs after adjustment, you can contact your after-sales specialist or call our after-sales hotline for assistance.
1. Incorrect support parameters. Check whether the correct support parameters are used, whether there are any broken or detached layers in the support, the first layer of powder should be thin, as thickness can lead to detachment;
2. The circulation is blocked, the air volume is too small, and the black smoke of oxides are not sucked away in time during the printing process. Please check the situation of the black smoke being blown away during printing, check the air speed, whether the circulation valve is open, and clean the circulation pipeline;
3. The powder is not sieved in time, and there are too many mixed oxides. Please clean the circulation and sieve the powder on time, and maintain the equipment in a timely manner;
4. The powder is damp and clumped. The powder needs to be dried;
5. The lens is not wiped in time, blocking the light and causing the laser energy input to be too low. Please wipe the lens with lens paper before each printing;
6. The equipment's sealing is not good, and the oxygen content is too high. Check the equipment's airtightness to ensure that the oxygen content during the printing process is not higher than 0.3;
7. The equipment's optical path is abnormal, and the laser focus position has changed, with too much defocusing causing low energy. Timely contact the after-sales technician to check the equipment's optical path and ensure the focus position is appropriate.
The conventional recommendation is to use a layer thickness of 25-30 for dental crowns and 30-35 for RPDs.
The smaller the layer thickness, the finer the printing effect, but the printing time will be correspondingly longer.

When using titanium-related powders, pay attention to the following:
1. Titanium-related powders should be sieved manually, using a plastic basin to catch the powder. Electric sieves have a high vibration frequency, which can easily cause frictional static electricity and lead to ignition;
2. After sieving, do not pour the titanium-related powder into a can, as the closed space inside the can can easily cause ignition. It is advisable to use a plastic basin or shovel to add the powder to the equipment's powder tank;
3. When sieving titanium-related powder, be sure to wear insulating gloves and anti-static wristbands, and wear anti-static clothing to avoid causing the powder to ignite due to human static electricity.
