Putting feet to the fire: A video test of Markforged’s Onyx FR’s flame retardant capabilities.
Time to play with matches! Because of the huge potential of an affordable & Flame-retardant composite plastic that can be 3D printed, we decided to put Markforged’s Onyx FR to the test.
In the video, we hung up two sample prints: One of Markforged’s standard-issue, chopped carbon fiber “Onyx” material (labeled ‘O’), and one of Markforged’s brand-new Onyx FR (labeled ‘F’).
After taking a blowtorch to the original Onyx Material for nearly 10 seconds, we saw it catch fire and start dripping melted plastic before the 10 seconds was even over! Putting the FR material in the blowtorch’s “hot-seat” for over 10 seconds barely affected it! As soon as we pulled the blowtorch away, the flame flickered out – not even a second later!
Below, you’ll find a short video showing the aftermath:
Hello, World! Matt Jones from Miller 3D here with the newest, exciting developments for the Markforged Metal X!
Today we decided to showcase the newest material that has been released by our partner: H13 Tool Steel.
You can check out the video to see our very first print of H13 Tool Steel in action in this post!!
If you didn’t know already, H13 Tool Steel is a game changer for manufacturing outlets demanding the strongest metal prints for their shops. H13 Tool Steel isn’t only well-known for its incredible strength: it has a very high wear resistance to thermal shock. The concentration of Vanadium in the material helps handle abrasion-focused applications at both high and low temps.
Because H13 also always provides a uniform and high level of machinability, this tool steel is often used for aluminum, zinc, and magnesium die casting.
H13 Tool Steel is also invulnerable to hot cracking, a problematic casting defect that the industry is all-too-familiar with the costly pains of reproduction.
