nGen_FLEX by colorFabb
Heat resistance 130C | Steam Sterilizable | Great layer-to-layer adhesion | Tough prints
nGen_FLEX was developed with Eastman chemical company. Based on their work with co-polyesters nGen_FLEX makes a very compatible materials with other Amphora grade materials. This means you can expect to mix both materials with good adhesion properties to truly form a dual extruded model.
* nGen_FLEX was designed to work with a Buildtak 3D printing surface and we find it does not adhere well to PEI (Lulzbut) print plates. If you have a PEI plate please consider Cheetah as an alternative.
With just the right amount of flex, nGen_FLEX is best described as a semi flexible materials. Still capable of being fed through a Bowden tube and printed at regular PLA speeds.

Heated platform – 80/100C
Advice on Using BuildTak – when printing on a brand new buildTak make sure the first layer is not pressed into the buildTak. There should be enough space between nozzle and buildTak, most likely more then you would normally use on a regular glass build surface.
Part removal from a BuildTak plate – when removing a part from the buildTak plate we advice to cool down completely and reheat to 80C. With a thin spatula, slide underneath the brim from all sides, then carefully continue with the rest of the model.
Build plate adhesion – most slicers will have the option for adding a brim around the printed object. colorFabb highly recommends to use this feature, removal after printing is very easy, the brim peals right off after making an initial cut.
Printing temperature – 240/260C
To reach higher speed / output of material, you might need to increase temperature. The material handles higher temperatures very well.
Minimal layer time
For colorFabb nGen_FLEX it’s also important to adjust the minimum layer time when you want to print without cooling for best layer adhesion.
PLA retraction values should be a good starting value for most machines. One can expect slightly higher values of retraction speed and retraction length. For more specific values have a look at our table above.
Coasting is a nice option included in Simplify3D. This is the act of stopping the extrusion just before a travel move is triggered, this helps get rid of the pressure in the hot-end and therefor also making a retraction move more effective.
