The process begins with an initial discussion to define the project's goals and requirements. This conversation helps us understand:

• The purpose of the part to be printed.
• The technical requirements, such as strength, dimensions, and material selection.
• Desired finish and aesthetic preferences.
• The quantity of parts to be printed.

Through this discussion, we determine the best technology for your project and provide a clear plan of action.

After the consultation, we will provide you with detailed instructions on preparing your 3D file. If you don’t yet have a 3D model, we can create one for you based on a drawing, sketch, or reverse engineering.

• File Formats: We accept various file formats, such as STL, STEP, OBJ, and IGES.
• File Check: We review the file for errors, such as open surfaces or incorrect dimensions, to ensure it is ready for printing.

If necessary, we also offer support to improve the 3D model for optimal print quality.

Depending on the project specifications, we choose the right 3D printing technology. We have several technologies that we use for optimal results:

• FDM (Fused Deposition Modeling): Ideal for functional prototypes and parts in various plastics, from basic to advanced (e.g., ABS, PLA, PETG, Nylon). This is a cost-effective option for larger quantities.
• SLA (Stereolithography): Perfect for detailed and precise parts made from photopolymers. This technology delivers exceptional finishing and is suitable for small batches and complex geometries.
• SLS (Selective Laser Sintering): This technique is used for printing strong parts from materials like nylon. It is ideal for functional parts and end-products.

We will be happy to advise you on the best technology for your product, taking into account costs, speed, and the desired properties of the final product.

Once everything is ready, we begin the 3D printing of the part. In this phase, the file is transformed into a physical object by applying the chosen technology. We build the object layer by layer, giving us the freedom to produce complex geometries that would be difficult or even impossible to create using traditional manufacturing methods.

Depending on the chosen technology and material, the printing time can vary from a few hours to several days for larger or more complex parts. During this process, we ensure that everything is printed precisely according to the specifications, and that the result meets the desired quality standards.

After printing, the object undergoes a series of post-processing steps to achieve the desired finish and functionality. Post-processing is essential for enhancing the overall quality and appearance of the printed part. This can include:

• Sanding and Polishing: Removing print lines for a smoother surface and improved aesthetic value.
• Painting and Coating: Optionally, we can paint or coat the object for additional protection or aesthetic purposes.
• Assembly: If necessary, we assemble multiple printed parts into a complete product.
• Removing Support Materials: For certain printing technologies, support materials used during the printing process must be removed.

We also offer different finishes, such as glossy, matte, or even transparent finishes, depending on the requirements of your project.

Quality control is a critical part of our 3D printing process. Each printed part undergoes thorough checks to ensure it meets the pre-defined specifications. We inspect:

• Dimensions and Tolerances: Ensuring the part has the exact required measurements.
• Material Strength: We test whether the part meets the mechanical strength required for its intended application.
• Functionality and Fit: If the part has a functional application, it is tested to ensure it performs correctly in the expected environment.

At RRU 3D Services, we believe it's important that every part is in perfect condition before being shipped to you.

After successful quality control, we ensure fast delivery of the printed parts. Whether you need small quantities or larger productions, we ensure timely and safe delivery so you can proceed quickly with implementation.

Thanks to the flexibility of 3D printing, we can swiftly respond to last-minute design changes, rapid prototyping, or producing small batches of parts. For large production orders, we can also handle follow-up orders quickly, minimizing lead times.
