Eager followers of our Twitter account have noticed that we have been printing quite a bit recently with PLA/PHA Natural in recent weeks:

And there is a good reason for this. PLA/PHA is our signature PLA filament which we exactly launched 4 years ago this month. The added PHA makes our grade of PLA tougher and less brittle than generic PLA grades in the market. PHA (polyhydroxyalkanoate) is like PLA a bio-polyester, so our unique blend is still 100% biodegradeable. This material is available in 30 colors, but today we focus on the one without a color: PLA/PHA Natural.

Due to the work of Spectra3D we have found that our filament is perfectly suited for investment casting. You can read our previous blog on Spectra3D’s work here.

Using 3D printing in investment casting reduces cost and adds flexibility to the process. PLA is a natural choice for this process where the entire print is burned out.

The results are phenomenal if we say so ourselves and we took ourselves to the task to print technical parts for investment casting ourself. Check out the results:

These engine block parts are a great design and you will see more of this design soon… (and that’s all we are going to say about this).

Another part we printed is intended for steel casting:

Both parts were printed on an Ultimaker 2 with a 0.6mm nozzle and 0.2mm layer height, resulting in a flawless surface quality.

In the past years, after the initial launch of our line of PLA/PHA filaments, we have released many other 3D printing filaments, like woodFill, bronzeFill, colorFabb_XT and one of the bestselling filaments: nGen. For a full timeline, click here. It is good, however, to go back to where it all started and find applications for the filament that started it all.

PLA/PHA Natural has been a favorite of professional designers ever since we launched it four years ago and has been a bestseller since. Our PLA/PHA range has received very good reviews over the years.

It has proven to be an extremely reliable filament for prototyping and investment casting.

PLA/PHA Natural is on sale this week. Get your spool now at a discounted price and find out the benefits of this filament soon on your own printer! Click here to go to the product page.

In the meantime, we keep printing…
