OPAM is a new all metal jot end with water cooling from Singapore developed by Leong Khit. It will be open sourced when the Indiegogo campaign finishes.The design is simplified by:
- Combining the nozzle, heater block and heat sink into 1 single piece of SS304
- Using water cooling as it is far more effective than air cooling
- Removing any PEEK or PTFE material
The benefits of a One Piece design are as follows:

Here is a detailed review by well known Thomas Sanladerer:
- No leaks/jams between the nozzle and heater block's contact surface
- No galling of the nozzle's thread (since it is built-in as part of the design)
- 1 piece construction (the nozzle, heater block & heat sink is combined into 1 single piece of SS304) to eliminate jams
- Water-cooled for high temperature extrusion of up to 350°C
- Short & Sharp transition from cold to hot portion (just 4mm)
- Built-in stainless stain nozzle
- Compact design (Light weight of 40 grams) for high speed printing
- Price: 60 USD for early-bird backers on IG
