Formed in place uses the same process to make an impression of the ear canal and outer ear and then turns that impression into the protector. Both types of custom molded earplugs are non-disposable with the laboratory made typically lasting for 3 – 5 years and the formed in place lasting for 1 – 2 years.

The first devices measured 1/4 inch by 1/8 inch (3.2 mm by 6.4 mm) and had 10 leads. [1] The flat package was smaller and lighter than the round TO-5 style transistor packages previously used for integrated circuits. Round packages were limited to 10 leads. Integrated circuits needed more leads to take full advantage of increasing device density.
Superparamagnetic microbeads: the monosized Dynabeads (scanning electron microscope image)Microbeads, also called Ugelstad particles [1] [2] [3] after the Norwegian chemist, professor John Ugelstad, who invented them in 1977 and patented the method in 1978, [4] are uniform polymer particles, typically 0.5 to 500 microns in diameter.
