The new Markforged materials make additive production a reality.
Professional 3D printing has never been so real
The last one was a month (and a year) of revelations for Markforged. Three new materials have been announced and others will follow as planned by the American company.
In late 2018, Markforged added H13 tool steel to its range of materials available and printable on the revolutionary Metal X. H13 is an ideal steel for working in a high temperature environment. The new material has joined the 17-4 PH stainless steel in the list of materials that Metal X can print.
But the material list has recently been expanded with the launches of White Nylon, Onyx FR and A2 tool steel.
White Nylon is stronger, stiffer and more reliable than traditional Nylon (Nylon Tough). The material has a smooth, non-abrasive surface finish and can be reinforced with any Markforged continuous fiber material.
Advantages of White Nylon
The material has many advantages over conventional nylon:
- Easier to print
- Stronger (and stiffer)
- More resistant to moisture (which improves room durability)
- Easy to paint
- Has a smoother final printing surface
The other great advantage is that the new material can be printed on the same extrusion head as Onyx (the other basic material for printing composites). In the past it was necessary to have two extrusion heads, one for nylon and one for onyx. Now we no longer need to change the nozzles when we want to print another material.
Which printers can print white nylon?
The 3D X7 and Mark Two printers
After the White Nylon, at the beginning of May 2019, was presented Onyx FR, the first fireproof plastic “reinforced” with continuous carbon fiber.
Onyx FR, flame retardant, is the new class V-0 flame retardant material designed for industries such as aerospace, automotive and defense. This material can be used for the industrial printers of the Markorged series (X3, X5 and X7).
The advantages of Onyx FR:
- Flame Retardant
- High quality surface finish
- High strength and low weight, especially when reinforced
- Heat and chemical resistant
- Reinforceable with continuous fibres
But, as mentioned, May was a “rich” month in terms of novelty and a few days ago, Markforged just announced the creation of a new material: A2. Especially Markforged is the only global company that can supply this new material.
What is A2 tool steel?
A2 is a cold working tool steel stamped on metal X.
It is found in tooling and assembly applications as well as in stamping and mold making workshops because it has a hard, wear-resistant edge.
It is applied for a larger number of applications requiring hardness and wear resistance above H13.
Why use A2 tool steel?
- Widely used general purpose tool steel
- Easy polymerization thanks to air cooling
- Higher wear resistance and hardness than H13
And Markforged has no intention of stopping as it is working on the development of new materials such as:
- 316L stainless steel (corrosion resistant and excellent weldability)
- Different tool steel variants (D2)
- Titanium (Ti-6AI-4V) ideal for lightweight prints with high mechanical resistance (especially in the aviation sector).
- Inconel 625 to develop parts that combine mechanical strength and heat resistance.
And much more…
