This process creates a smooth, matte finish using abrasive media, perfect for applications that require an improved aesthetic with uniform surface texture. It enhances the part’s surface while retaining strength.

Machined Surfaces

For parts that require extra precision, our machining process can further refine surface details, providing a high degree of smoothness and dimensional accuracy for tight tolerance applications.

Polished / Cosmetic Finishing

Achieve a glossy, mirror-like finish suitable for decorative or high-visibility parts. Polishing removes any surface imperfections, providing a smooth, aesthetically pleasing result ideal for consumer-facing applications.

Polished

Provides a high-gloss finish that enhances the appearance and smoothness, ideal for parts that require both beauty and function.

Cromado duro

Adds a thick coating that boosts hardness, wear resistance, and durability, perfect for high-stress parts like shafts and pistons.

Niquelado

A thin, electroplated nickel layer that enhances wear and corrosion resistance, providing an attractive finish for functional parts.

Óxido negro

A chemical treatment that creates a dark, matte black surface on steel parts. It offers mild corrosion resistance and reduces light reflection.

Design Guidelines for Direct Metal Laser Sintering (DMLS)

For optimal performance and cost-efficiency, understanding and following design guidelines for Direct Metal Laser Sintering (DMLS) is essential. These guidelines ensure your parts are fabricated with the highest strength, accuracy, and cost-effectiveness, meeting both functional and aesthetic requirements.

	Plásticos: 1.0 mm (required to prevent warping or structural issues)
Límites de tamaño de los elementos	Smallest features: 0.2 mm for precise detail and geometry.
	Larger features require careful balancing to ensure strength and structural integrity.
Support Structure Considerations	Use minimal support structures to reduce post-processing efforts. Ensure structures are easy to remove without damaging the part.
	Supports must be designed to avoid internal stresses and support complex geometries.
Orientation for Strength & Accuracy	Parts should be oriented to optimize mechanical properties in critical load-bearing areas.
	Maximize strength by aligning with the build direction.
Design Tips to Reduce Cost	Minimize the need for support structures by designing parts with self-supporting geometries.
	Keep geometries simple and avoid overly intricate features unless required for functionality.
Tamaño y profundidad de los orificios	Avoid excessively small holes (min. 0.2 mm) and ensure sufficient depth for chip removal.
Internal Geometries	Complex internal channels, like cooling channels, can be created but should have a minimum width of 0.5 mm.
Part Consolidation	Consider consolidating multiple components into a single part to reduce material waste and cost.
