Small parts manufacturing from acrylic and nylon is chosen when a very precise contour and clearly defined part geometry are required. Unlike wood-based materials, these plastics do not have a layered structure, so small parts retain their shape and edge accuracy even with dense cutting patterns.
Acrylic (PMMA) is valued in small parts manufacturing because laser cutting allows achieving extremely sharp contours and minimal deviation in cut width. In practice, it is important to distinguish the type of acrylic: cast acrylic is better suited for very small parts, as the cut edges are more uniform, while extruded acrylic is more sensitive to heat and may require larger spacing between elements.
Nylon is used for small technical parts where not only shape but also mechanical properties are important. It is not as brittle as acrylic, but it reacts more to heat during laser processing—the cut edges may be slightly softer, which is why nylon is more often chosen for functional rather than highly decorative small parts.
When designing small parts from acrylic, it is essential to consider the minimum wall thickness, as overly thin elements may break after production even if the cutting itself is precise. It is also important to know that very dense cuts close to each other can cause localized material overheating.
In the case of nylon, the main consideration is thermal behavior. In very small areas, the part may slightly deform during cutting, so design adjustments or test cutting are often recommended. If the parts are critical or must fit together precisely, a test cut is almost always the best solution.
