Laser Microcutting Services

MLPC’s laser microcutting capability is an invaluable service for medical device OEMs, medical suppliers, and companies involved in medical research and development.

Production Overview

From prototype to full scale production, MLPC experts are ready to meet all your microcutting needs. Various types of cuts available with this process include: holes – to 0.001" in diameter; slots – to 0.001" wide; constant, variable pitch spirals; and flex tubes – interlocking links

Typical critical functions of microcut hypotube are torque transference, tensile strength, and radius of curvature. To find the right microcut pattern, FEA modeling can be utilized. Mound Laser's engineers specialize in developing microcut patterns to meet functional part needs.

Finite Element Analysis

Combining Finite Element Analysis (FEA) with early stage prototype development, allows for a customize cut pattern to meet the functional needs of the application. Through FEA, torque and tensile requirements can be tested and established prior to processing the first prototype. This analysis allows engineers to quickly develop the right geometry based on the applications path through the body.

To evaluate applications, Mound Laser uses the radius of curvature, tensile, and torsion requirements which are input into the FEA package. Upon the completion of the simulation, minimum and maximum strain patterns are plotted against the 3-D model to show areas of potential design improvement. Our engineers adjust design parameters to optimize product performance given the customers requirements.  The images above highlight FEA modeling of nitinol to be optimized through the aortic arch.  In our laser myth buster #3, we show that by utilizing FEA modeling stainless steel can be cut to mimic the performance of nitinol through the aortic arch.  To read more, click here.
