3D Printing for Electronics & IoT

The problem you are actually solving

Off-the-shelf project boxes are the wrong size, have no cutouts where your connectors are, and no mounting bosses where your board needs them. You end up drilling, filing and bodging, and the result looks it.

The alternative, tooling a custom enclosure, costs lakhs and takes weeks, which is impossible to justify for a pilot deployment of forty units.

And for outdoor deployments there's a second problem nobody warns you about: most plastics degrade in Indian sun within a season.

Materials that suit this work

• PETG

  PETG

  The default for indoor enclosures. Tough, cheap, handles 75 °C.

• ASA

  ASA

  Mandatory for anything outdoors. The only UV-stable filament we stock.

• PC

  PC

  When the electronics run hot, 110 °C service temperature.

• TPU

  TPU 95A

  Printed gaskets, strain reliefs and shock-absorbing feet.

Not sure which applies to your part? Use the material selector , four questions and it tells you, with the reasoning.

The questions electronics & iot customers actually ask

• Will the connector cutouts actually line up?

  Tolerance stack-up between the connector on your board, the board in the enclosure and our ±0.20 mm means you should assume about ±1 mm of positional uncertainty. We oversize cutouts by 0.5 mm all round to absorb it, and for a critical port we recommend printing a small test coupon of just that face first. It costs the ₹350 minimum and eliminates the most common reprint.

• Can you make it waterproof?

  We can design for ingress protection, gasket channel rather than a flat mating face, 2 mm minimum walls, proper cable glands, sloped surfaces. What we can't do is certify an IP rating, because that's a test result, not a design intention. If you need a certified rating, the enclosure has to go to a test house.

• Will heat from the board deform the enclosure?

  It can, and this is the mistake we see most. PLA softens at 55 °C, which a warm regulator inside a sealed box reaches easily. Tell us the internal temperature and we'll pick a material with headroom, PETG to 75 °C, PC to 110 °C, and advise on vent placement.
