I was asked to create and print a replacement handle for an Brewista electric kettle - here it is available to everyone.

First of all, definitely do not use standart PETG or PLA. Naively, I tried to make a replacement from PETG, and even though everything fit perfectly, the handle couldn't withstand the heat, and the threaded inserts literally slipped out.

The model is prepared for threaded inserts - I personally use inserts from CNC Kitchen. Here are the links to purchase/insert dimensions:

Given that the kettle's body is metal, you should consider the maximum possible temperature - which is very close to 100°C. Suitable materials for printing are likely ABS, ASA, or possibly extremely durable specialty materials that operate in this range.

As a last alternative, there is heat annealing – I personally have no experience with it, but I've seen a few videos on the topic. In any case, the final decision is up to you! For example, Fiberlogy HD PLA, which I’ve read has heat resistance up to 140°C after annealing in an oven.

I am attaching the instructions for Fiberlogy HD PLA, from which I personally draw information:

  • Print your project.
  1. Print temperature: 200 - 220 °C
  2. Bed temperature: 50 - 70 °C
(Heating the bed is not necessary if you are using pads, tapes, or adhesives that enhance adhesion.)
  • Allow the model to cool down after printing (with supports and raft still attached).
  • The print should be placed in the center of the chamber (oven), evenly spaced from the heating elements inside.
  • Gradually heat it to a temperature of approximately 80 °C.
  • Anneal (bake) for about 15 minutes at 80 °C.
        WARNING: The temperature in the chamber (oven) must be maintained precisely. 

We recommend monitoring the temperature with a suitable digital thermometer inside the oven. The print needs to be watched during the heating process. For large prints, you may gradually increase the temperature to 120 °C or extend the annealing time.

  • After annealing, remove the print along with the pad it was placed on in the chamber, and avoid touching it until it cools down (to room temperature).
  • Remove supports and raft.
  • You can now use the finished product, which has gained mechanical strength similar to ABS and heat resistance up to 140 °C. The model may soften at such high temperatures but will not melt and will hold its shape.

 

GOOD LUCK PRINTING!
