What You'll Learn
Accuracy of automatic painting in 3D printing Prusa
The accuracy of automatic painting in 3D printing with Prusa depends on several factors, including the chosen material, printer settings, and post-processing techniques.
Prusa offers a Multi-Material Upgrade 3 (MMU3) add-on for its 3D printers, which enables automatic colour changes during the printing process. This allows users to print with up to five different colours in a single layer, enhancing the visual appeal of their creations. However, it's important to note that the accuracy of colour distribution may vary, and blending multiple colours within a single layer can be challenging.
Prusa also provides a range of post-processing courses, such as the Prusa Academy, which offers guidance on painting and detailing 3D printed models. These courses cover various techniques, including brush painting, spray painting, and advanced methods like imitating metallic surfaces and sparkling gemstones using regular paints.
To achieve accurate results, users should pay close attention to the chosen printing material and its characteristics. For instance, materials like PLA or ASA are recommended for certain parts due to their low cost and reduced warping tendencies. On the other hand, high-cost materials like PEEK composites are prone to warping and absorbing moisture, which can affect the accuracy of the printed object's dimensions and surface finish.
Additionally, printer settings and calibration play a crucial role in achieving accurate results. Proper calibration ensures that the printed object matches the desired dimensions and that circular pieces fit together precisely. Prusa offers tools like PrusaSlicer and ArcWelder to optimise print settings and improve accuracy, especially when dealing with curved shapes.
Overall, while automatic painting in 3D printing with Prusa offers convenience and creative possibilities, achieving accurate results requires a combination of careful material selection, printer calibration, and post-processing techniques.

Multi-material painting
Multi-material 3D printing is a process that involves printing several materials in one continuous printing process. The basic aim of multi-material printing is to achieve a combination of different material properties, such as conductivity, hardness, softness, transparency, and chemical resistance, which are particularly suitable for specific applications. This technique is not the same as multi-colour printing, where one material is printed in several colour variations. However, the visual result of multi-material printing can be that it contains several colours.
To create a multi-material 3D print, you can use software such as Canvas, which allows you to select and paint different colours on the objects in your print bed. You can use tools like the facet tool for precise triangle painting or the sphere tool for covering larger areas. Additionally, you can configure custom supports and remap inputs to correct errors and ensure the desired colours are used.
Prusa 3D printers offer courses on post-processing and painting, including basic brush painting and advanced techniques like imitating metallic surfaces and sparkling gemstones using regular paints. They also offer a course on multi-material printing using multiple print heads with their Prusa XL printer.
For successful multi-material 3D printing, it is crucial to set the correct slicer parameters and provide corresponding instructions in the G-code, depending on the printer configuration. FDM (Fused Deposition Modelling) is a commonly used method for multi-material printing, known for its cost-effectiveness and simplicity. It allows the processing of various thermoplastic polymers and composite materials.

Painting tools and methods
Airbrushing offers excellent control and precision, making it ideal for detailed 3D models that require gradient effects or fine colour work. It requires an airbrush tool, compressor, and a certain level of skill to build up thin coats for a smooth, professional finish. Acrylic paints and dedicated airbrush paints work well for airbrushing as they are easy to thin and clean.
Hand painting can be done with brushes or palette knives, and can be used to create interesting textures and intricate designs. Brushes can be 3D printed with custom handles and bristles tailored to specific painting needs, and palette knives can be created in various shapes and sizes for different techniques. Stippling, a technique that creates texture by dabbing paint onto the model, can be achieved with a brush or sponge and is particularly effective when a uniform, smooth surface is not required.
Prusa offers courses that cover the basics of brush painting, spray painting, and more advanced methods such as imitating metallic surfaces and sparkling gemstones using regular, non-metallic paints. Other techniques include masking, which uses masking tape or liquid masking fluid to achieve crisp lines and sharp edges when applying multiple colours, and the use of a dark wash over a lighter base coat to create subtle shading effects that give the model depth and dimension.

Dimensional accuracy
One key factor is the choice of printing material. Materials like PLA or ASA are often more reliable for dimensional accuracy than high-cost materials like PEEK composite, which is prone to warping and moisture absorption, leading to deformation. For example, when printing iPhone and Apple Watch charger ports, the part with the round base was geometrically accurate, while the one with the square base was warped and dimensionally deformed due to moisture absorption.
Another factor is the print settings, such as layer height and nozzle size. Adjusting these settings can significantly impact the accuracy of the print. For instance, a user reported an issue with dimensional accuracy, resulting in a diameter of 27.15mm instead of the expected 28.35mm. Suggested solutions included reducing the layer height to 0.15mm and using a smaller nozzle size of 0.4mm to improve accuracy.
Additionally, the complexity of the design can also affect dimensional accuracy. A review of the Prusa Pro HT90 printer highlighted the printer's ability to produce dimensionally accurate prints, even for relatively intricate designs. However, the reviewer noted that more complex shapes, such as circles, may require additional adjustments to achieve accurate results.
To ensure dimensional accuracy, it is recommended to perform test prints with the same parameters and filament as the final print. By tweaking the dimensions based on these test prints or test fits, users can refine their settings to achieve the desired accuracy. This iterative process is particularly important when dealing with circular pieces or complex shapes.
Furthermore, Prusa offers features like the Multimaterial Paint function, which allows users to select specific areas of their model to colour. This feature, combined with the Multi Material Upgrade 3 (MMU3), enables automatic colour changes during printing, enhancing the overall accuracy of the printing process.

Calibration and setup
Initial Setup:
The initial setup of a Prusa 3D printer is relatively straightforward. After unboxing and removing the protective packaging, the printer can be powered on and the initial setup can be completed via the touchscreen interface, similar to setting up a mobile device.
First Layer Calibration:
Every Fused Filament Fabrication (FFF) printer, including the Prusa models, requires First Layer Calibration. This process sets the vertical "Z" distance between the nozzle and the print surface, ensuring the first layer of the print adheres correctly and is essential for overall print quality.
XYZ Calibration:
Prusa 3D printers, such as the Original Prusa I3 MK2, offer automatic XYZ calibration. This process corrects the geometry and ensures the printer axes are perpendicular to each other. It measures the skew of the X and Y axes and uses an induction sensor to find the correct sensor points. This calibration achieves an accuracy of approximately 0.2 degrees in the skew of the machine axes, resulting in a deviation of 0.5 mm over the print bed width.
Automatic Bed Calibration:
The Original Prusa I3 MK2 features automatic bed calibration, which includes full mesh bed auto-levelling. This function relies on an induction sensor mounted on the print head to sense its distance towards nine induction targets arranged in a 3x3 grid pattern on the heated print bed. While automatic bed calibration simplifies the process, it requires the printer to be assembled with higher accuracy than previous models.
Maintenance and Skew Correction:
Over time, the printer may require recalibration due to transport, assembly, or maintenance. The XYZ calibration procedure can compensate for skew caused by loose belt pulleys, an unsecured print bed, or nozzle deflection. Regular calibration helps prevent print bed damage and accidental damage to the print surface due to mechanical parts loosening or breaking.
