Comments related to etching technology:
From @chadr2604:
There is another way it involves stacking many layers of very thin material with an There is another way it involves stacking many layers of very thin material with an adhesive, pressing the stack, then either stamping or punching the blank then heating it to release the adhesive. The parts will not be as accurate the tolerance is limited to about .002″ but if its good enough its much faster.
From @chadr2604:
If you try to cut that stack with a laser you will just start a fire we had an aluminum fire trying that.

Modern precision sheet metal fabrication includes a common technique known as etching, which differs from traditional sheet metal fabrication in several ways. Here are some key differences between etching and traditional precision sheet metal fabrication:

  1. Principle: Traditional sheet metal fabrication typically involves mechanical processes such as cutting, bending, and punching to shape and form metal sheets. Metal etching by Metal Etching Machine , on the other hand, is a chemical process that uses specialized etchants to selectively corrode the metal surface, achieving precise etched patterns and features.
  2. Accuracy and Complexity: Etching offers advantages in terms of precision and complexity. By controlling the composition, concentration, temperature, and etching time of the etchant, extremely fine etching can be achieved with accuracy down to sub-micron levels. Additionally, etching allows for the creation of intricate geometries, microstructures, and patterns that may be difficult to achieve using traditional mechanical methods.
  3. Processing Speed and Cost: Etching generally offers faster processing speeds, particularly in large-scale production. In comparison, traditional mechanical fabrication methods may require more time and cost to achieve the same level of precision and complexity.
  4. Materials Compatibility: Etching techniques are applicable to a range of metal materials, such as copper, aluminum, stainless steel, and titanium. Traditional sheet metal fabrication methods may have limitations when it comes to certain materials or thicker metal sheets.
  5. Design Flexibility: Etching provides greater design flexibility. By incorporating techniques like photolithography or screen printing during the etching process, complex patterns and structural designs can be achieved. This makes etching suitable for applications in microelectronics, optical devices, microfluidic devices, and more.

Characteristics of Elgiloy:

Apart from the above features, Elgiloy has other notable characteristics, which make it a popular material in many industries. These include:

Excellent fatigue resistance: Elgiloy has excellent fatigue resistance, making it an ideal material for applications subjected to repeated stress or load cycles.

Biocompatibility: Elgiloy is biocompatible, making it suitable for medical applications such as implants.

Magnetic properties: Elgiloy exhibits magnetic properties, making it suitable for electromagnetic applications.

In conclusion, Elgiloy is a highly specialized material with unique characteristics that make it an ideal choice for chemical etching applications. Its high corrosion resistance, high strength, and good ductility make it suitable for various industries. Additionally, the excellent fatigue resistance, biocompatibility, and magnetic properties of Elgiloy make it a popular choice for medical and electromagnetic applications.
