Markforged X7 - Continuous Carbon Fiber, Kevlar, Fiberglass 3D Printer: Fabtech 2019 Overview

Показать описание
Catching up with Brendan again, he takes us through the Markforged X7 and it's new features -- a bit larger, a bit improved, and featuring the fabled continuous-fiber technology.

While we work with open systems at Vision Miner, Markforged has a closed system that is hard to beat -- if you've got the extra cash. We basically say, if you have a ton of money and don't want to learn new things, go for the Markforged. If you want to learn your machine inside and out, save money, and have a plethora more options -- go with something open source.

On the Markforged, though, it's quite impressive the systems they've released the last few years, and their focus on manufacturing is helping the entire industry at large -- with plenty of use-case examples, you can really get an idea how this technology is being used in real-world applications.

Again, a great buy on an unlimited budget. However, the Onyx material is not only expensive, but not as strong as the open-material market's current offerings, such as 3DXTech's CarbonX Nylon. You're also limited to a single nozzle -- no support structures with this printer. Furthermore, because of the closed system, you're limited to their materials -- at their cost. Want to do a test run in a less expensive material? Nope, not going to happen.

With open materials systems, you do have to learn a lot more -- it's not ALL cost savings -- you need to learn the machine itself, a slicer program like Simplify3D or Cura, and each material you switch to will require some tuning -- figuring out the correct basic settings for your machine. While straightforward, this is not always easy.

Markforged stands out with flying colors because -- if you can afford it, you'll get a great-looking, strong part -- most of the time, without much effort.

At Vision Miner, we specialize in Functional 3D printing on open-material systems, especially high-performance plastics like PEEK, ULTEM, PPSU, PPS, CFPA, and more. Metal-replacement thermoplastics.

If you're interested in using functional 3D printing and materials in your business, feel free to reach out, and we can help you make the right choice for your application.

So cool, as strong as aluminium, unreal. So exciting where 3D printing is going. Puts my Ender 3 to shame but still love my Ender.

It's really misleading to say those parts are as strong as aluminum (1:1 for 6061). Ultimate tensile strength in the optimal direction on a part designed for the test, it achieves the tensile of 6061 but you can not replace MOST aluminum parts with these printed parts, even when ONLY considering room temp strength. I own a machine shop and have 3D printers capable of carbon fiber PEEK and Ultem. I make lots of parts from 6061 as well as 7075 Al and would LOVE it if I could print parts to replace most of the aluminum parts we make for customers. The reality is that plastic (even continuous carbon fiber reinforced) is not as strong as aluminum, particularly if you stray to far from room temp. There are few parts that can be swapped out. 1:1 for 6061 aluminum is BS. A huge stretch at best. This is a great printer and continuous fiber is better than a chopped fiber impregnated filament but this sales pitch is fantasy.

possibilities are exciting indeed. When you mentioned as strong as aluminium, i wondered how much stronger it could go?
