What is Acrylic?

Acrylic is a lightweight thermoplastic recognized for its crystal-clear appearance, sterilization resistance, weatherability, and dimensional stability.

Introduced in the 1930s as polymethyl methacrylate (PMMA), acrylic is available in clear and tinted forms and widely used in surgical tools, diagnostic housings, and laboratory equipment. Modern CNC machining enhances its precision and reliability for safe, high-quality medical components.
Advantages of Acrylic
- Excellent light transmission: Acrylic allows up to 92% light transmittance, offering superior optical performance for medical lenses and transparent enclosures.
- Low water absorption: It maintains dimensional accuracy and prevents swelling or warping in humid medical environments.
- Easy fabrication: Acrylic can be precisely cut, drilled, or shaped, supporting complex medical designs and custom prototypes.
- UV resistance: It retains clarity and color even after prolonged exposure to light or sterilization lamps.
- Chemical stability: Acrylic withstands exposure to disinfectants and cleaning agents without degradation.
- Cost efficiency: It provides a durable, glass-like appearance at a lower cost for high-volume manufacturing.

Can MedCNCParts provide rapid prototypes using acrylic?

Yes. We offer rapid CNC prototyping for acrylic parts, allowing medical device developers to test designs quickly before production. This service helps reduce lead time and speeds up regulatory validation.

Can MedCNCParts produce small and complex acrylic parts for medical devices?

Yes. Our precision CNC machines can produce detailed acrylic components as small as 0.5mm with tight tolerances up to ±0.005mm. MedCNCParts’s expertise in micro-machining ensures accuracy even for intricate geometries used in lab and diagnostic equipment.

How does MedCNCParts prevent cracking or surface stress in acrylic parts?

Acrylic can be prone to stress cracking if machined incorrectly. MedCNCParts’s engineers carefully control spindle speeds, feed rates, and cooling methods to minimize internal stress and ensure long-term durability under sterilization and handling.

What finishing options does MedCNCParts offer for acrylic medical parts?

We provide a range of finishing services such as flame polishing, vapor polishing, and surface buffing to achieve crystal-clear transparency. Optional laser marking is available for part identification, traceability, and branding.

Are MedCNCParts’s acrylic parts suitable for sterilization and medical compliance?

Yes. All acrylic components are produced under ISO 13485 and ISO 9001-certified processes. The material is compatible with standard sterilization methods, and each part is inspected for cleanliness and dimensional accuracy before delivery.
