PolyWood vs WoodFill

15 Jun Les Imprimantes 3D compares PolyWood to WoodFill

Les Imprimantes 3D, a French news and forum company for the 3D printing industry have published a comparison of two popular wood mimic filaments, Polywood and Woodfill. Here is a translated version of their article.

Woodfill, Laywoo, Polywood … Today, there are many wood filaments on the market, and at first sight they all appear virtually identical. However, they each have their own characteristics and specific applications. I’ll be testing for you two wood filaments that I selected. The Woodfill and Polywood.

.

Presentation of filaments

 

PolyWood vs WoodFill

Polymaker’s Polywood and ColorFabb’s Woodfill side by side.

 

The Woodfill

Woodfill by Colorfabb as of today is the most popular wood filament available on the market. But it is not appreciated by all makers. Indeed, this filament is known to easily clog 3D printers, because it is composed of 30% very fine wood fibers that can burn and block the extrusion. At first glance, this filament is however very aesthetically pleasing with a matt appearance and a pleasant woody smell.

The Polywood

The Polywood is a wood mimic filament by Polymaker. Unlike Woodfill, it is not composed of wood but of plastic, with a colour and a texture comparable to those of wood. The risk of clogging the nozzle seems nonexistent with this filament. The material itself is slightly shiny, confirming the absence of wood fibers.  PolyWood is the first and so far the only 3D printable material with a foam core structure. The density of PolyWood is on average 0.8 g/cm³ which is 35- 40% lighter than regular PLA. This material density is very similar to natural wood giving the filament a woody feel.

The Test Parameters

 

For this test, we will print a filament object to award each of them a note. Here are the print settings appropriate for each filament that we will test:

For Woodfill:

  • Extrusion temperature: 220 ° C
  • Heated bed (optional): 40 ° C
  • Extrusion speed: 70 mm / s
  • Filling: 60%
  • Layer height: 0.2 mm
  • Printed piece: (a Bitcoin)

For Polywood:

  • Extrusion temperature: 205 ° C
  • Heated bed (optional): 40 ° C
  • Extrusion speed: 70 mm / s
  • Filling: 60%
  • Layer height: 0.1 mm
  • Printed piece: (logo Open Hardware)

 

Test results

 

And after an hour of printing, here’s the result:

Compare Woodfill VS Polywood

 

We note that the glossy appearance of Polywood has completely disappeared. Both models have almost the same texture, but not the same colour. We can also notice a big difference in quality between the two parts. Indeed, the Woodfill causes at times micro cavitation which prevents extrusion for one or two seconds. The piece thus has a few holes in some places.

Problems encountered

Polywood

With Polywood, I started with a print infill of 20%. The end result was poor because the last layers of the infill are not well covered spaces due to the relatively low load factors.

There is absolutely nothing wrong though. You just have to select an infill of at least 50% during the slicing process on the computer, and voila! Aside from that, the infill is of a very high quality, with a realistic wood appearance. The filament can withstand without problems very fast print speeds.

On the side of Woodfill

As soon as I started using Woodfill the problems began. Indeed, what I feared had happened: the nozzle is clogged twice because of the wood fibers, completely preventing extrusion and requiring discontinuation of the print. This material should not be extruded too slowly, otherwise the filament stagnates, and clogs the nozzle. On the contrary, it cannot be extruded too quickly because it breaks. We must find the right printing speed and at all costs avoid leaving the filament in the heated nozzle without extrusion (when the printer cools after printing for example).

 

Notes and Conclusion

Woodfill

Difficulty: 1

2 Originality:

Quality of room: 3

Price: 4

Final grade:  2.5 / 5

 

Polywood

Difficulty: 6

Originality: 7

Quality of room: 7

Price: 4

Final grade:  4/5

For the same price (about € 50 for a 1 kg spool), these two filaments are radically different. I am not convinced by the Woodfill because it is complicated to use and the quality of the final piece is average. The Polywood is itself very simple to use because it has the same properties as a conventional PLA. The infill once complete is of great quality, with a pleasant texture to the touch.

Although Polywood is for me better than Woodfill, I urge you to test these filaments to form your own opinions!

    Is the material hydrophilic or hydrophobic
    thank you

    I thought acetone vaporising only works with ABS. Polywood is not a ABS filament, correct?

      Yes Acetone normally only working with ABS and our PolyWood is a PLA based material so we were quite surprised to see one of our loyal customers test this and come out with such impressive results. We are in fact working on an extremely interesting product, which I beleive you will be very interested in.
