ESD

Parts that must not build up a charge.

Electrostatic dissipative parts in PETG-ESD and PA612-ESD, printed to order. For workplaces where a discharge you cannot even feel ruins a board.

An ordinary printed holder is an insulator. Slide an assembly across it and the friction builds a charge, and that charge leaves through the first conductive thing it meets. With electronics, that is the component itself. The damage is often invisible and only surfaces months later as field failures.

ESD materials solve that by bleeding the charge away slowly and in a controlled way instead of trapping it. The part is not conductive like metal, it is dissipative: high enough in resistance not to short anything, low enough not to charge up.

We print that in two materials: PETG-ESD, filled with a conductive compound, and PA612-ESD, a nylon. Which of the two fits depends on the heat the part has to take.

Materials

Two ESD materials, each for something else.

PETG-ESD

The workshop choice: trays, bins, holders and assembly aids on an ESD bench. Without load about 65 C, under load about 60 C (the heat deflection temperature from the manufacturer minus a 10 C margin).

PA612-ESD

For what has to take more heat than PETG-ESD allows: guides, stops and fixtures that components move along. Without load about 145 C, under load about 115 C, dry and after annealing. It is a nylon, so it takes up moisture and gets a little less stiff when damp; keep it dry.

When it does not fit

If your standard asks for a genuinely conductive part, or a measured surface resistance per piece, printed ESD material is the wrong answer; choose metal or a certified semi-finished product. We print dissipative, we do not measure resistance per unit.

Typical work: fixtures and trays for board assembly, holders for sensitive sensors, guides in a test rig, and replacement parts for existing ESD furniture the supplier no longer serves.

Neither material is held in stock; both are bought in for your job, which fits inside the Standard timing (production starts from 5 working days). The quote tool shows which speeds are possible for these materials; what to expect for your part is stated with your quote.
