Laywoo-D3 flex is a semi-flexible wood-fill filament.

Temperature: This printed nicely between 190°C and 255°C with varying colour as the temperature increases, if you print up to approximately 225°C the colour will be a lighter tone than 225°C to 255°C this is not a sudden change so allow 15-20 degrees difference to see the colour change.

Speed: Printing speed was ideal at 40mm/s or 85% of normal speed if 50mm/s is standard, for higher speeds temperature needs increasing.

Preferred settings: it would print nicely at 0.1mm, an initial layer height 0.2mm, speed 40mm/s, with lesser retraction settings, a little oil in the Bowden tube will help reduce the friction. Printed well with both standard Brass and Ruby nozzles, retraction didn’t eliminate stringing but helped a little with the flexibility and not wanting to squash the filament on the feeder, I would suggest just a little retraction. They recommend a minimum nozzle size of 0.5mm, and although would print with a 0.4mm nozzle it does require a good extruder, the stock UM2 and modified Roberts feeder would fail, but a bondtech feeder would print successfully with the 0.4mm nozzle.

Ultimaker Robot: Printed well looking like a wood effect bridging and overhangs could improve with reduced print speed, small sections like the hands and antenna printed a little darker due to the material being in the hot zone of the head for longer.

Tree Frog: Printed a nice model, good all round definition of the features with a slightly reduced speed, any stringing was easy to trim with this filament.

3DBenchy: A good build although has some stringing which I left on for the photos but is easy to trim away.

On thin walled or skinned components the print has some small flexibility, although on my standard test prints it was not very flexible.

Shrinkage - Length % Width % Height* % Dimension 60mm - 31mm - 32.5mm - Measurement and % Difference 59.85mm 0.25% 30.93mm 0.23% 32.46mm 0.12%

*As the vertical height can be effected by the distance of the bed-levelling to the nozzle the height of the “Top of the Chimney to the top of the box” should be more accurate for the comparisons

Conclusion: Although possibly needing a 0.5 nozzle or larger, or a very good feeder for printing with a 0.4mm nozzle, this was another nice filament from Kai Pathy, a good top surface on flat pieces was obtainable, this is well worth giving a try, but you will need a 0.5mm nozzle and to find your ideal print settings. Unfortunately I did not have enough sample to run all the test pieces but will update the findings at a later date.

Testing performed on an Ultimaker2, With a BondTec Feeder, an Olsson Block running a 35W heater and using a 0.4mm nozzle.
