Cleaning devices

Professional cleaning of printed objects

Cleaning printed objects is far more than just an intermediate step in 3D printing. It is crucial for the biocompatibility and mechanical properties of the finished objects. After the printing process, uncured resin must be completely removed - this is the only way to achieve optimum properties. Inadequate cleaning leads to reduced strength, thickened surfaces and impaired accuracy of fit. Biocompatibility can also be negatively affected by residual resin. Our developers and material experts work intensively with all components of dental 3D printing and have always been aware of the importance of cleaning. The two-stage cleaning concept we offer guarantees reliable results and creates the basis for subsequent post-curing.

The RS wash cleaning device

The RS wash cleaning device combines innovative technology with simple operation. The fully automatic system automatically selects the optimum cleaning programme in conjunction with RS printers. The patented two-stage pre-cleaning and final cleaning process ensures reliable results while minimising cleaning agent consumption. The intuitive touchscreen control makes operation particularly easy.

Cleaning 3D printers and other components

Cleaning the 3D printer and its components is also crucial for consistently high-quality printing results. We have developed a special cleaner that effectively but gently removes resin residues and impurities. The cleaning formula has been specially adapted to the requirements of dental laboratories. It is gentle on materials and easy to use: spray on, leave to act briefly, wipe off - done. Even hard-to-reach areas are reliably reached thanks to the spray application. The result: clean components for precise printing results and a longer service life for the devices.

Frequently asked questions about cleaning in 3D printing (post-processing)

Why is professional cleaning so important?

Cleaning is crucial to the subsequent properties of the printed objects. After the printing process, there is still uncured, liquid resin on the object, which must be completely removed. This is the only way to optimise post-curing, which is crucial for mechanical strength and biocompatibility. Inadequate cleaning can lead to thickened surfaces, reduced precision and impaired material quality.

What is the optimal workflow?

After the printing process, the post-processing phase begins. The object is first carefully removed from the build platform - care is required here to avoid damage. The subsequent cleaning ideally takes place in two stages: The first cleaning step removes most of the uncured resin. The second cleaning stage then ensures the final surface quality. Thorough drying is followed by light curing, which ensures the final material properties.

Which cleaning agents are suitable?

The most important aspects of cleaning:

• Isopropanol as a standard solution
• TPM (tripropylene glycol monomethyl ether) as an alternative
• Water-based solutions for easier handling
• optiprint clean, our special cleaning fluid for removing resin residues
• Follow the manufacturer's material-specific recommendations
  

What common mistakes should be avoided?

If the cleaning time is too short, resin residues are left behind, which can impair subsequent curing. At the same time, cleaning for too long, especially with alcohol-based solutions, can reduce the strength of the material. The choice of cleaning agent is also crucial: while isopropanol is ideal for most materials, ethanol is only suitable for certain resins. The manufacturer's instructions provide the most important points of reference here.

What needs to be considered when handling cleaning agents?

Handling toxic cleaning agents requires care. A well-ventilated workplace is essential. Gloves and safety goggles are part of the basic equipment. Special care must be taken when storing the mostly flammable cleaning agents and disposing of them properly. When working with ultrasonic baths, particular attention must be paid to the combination with alcohols, which can be explosive.

How can cleaning be organised in an environmentally friendly way?

Modern cleaning systems such as the RS wash work with closed cycles and minimise material consumption. The trend is increasingly moving towards water-based solutions, thereby reducing the environmental impact. Used cleaning agents must be disposed of properly.
