UNBOXING & First Prints: Markforged Mark Two 3D Printer! 

Why was that your initial though... prior to knowing who and why someone bought it? Is it pricey, ie overpriced?

how much is that printer ?

@@danrusu The Mark Two is about 25000€ The Onyx Pro with can "only" print Onyx and Carbon fiber costs about 12500€

What’s the price ?

Unusefull printer you can not use a difetent materials and Onix is expensive compared with... This 3D printer do not allows you to set a temperature different than 275°C Does any body knows any way to modify the temperature in order to use it with a diferents material?

Make sure you have a proper nozzle for it so the filament doesn't destroy it.

Actually, i have seen no other FDM printer, regardless of filament, giving as nice surface finish as the markforged does, it comes down to a very good filament and extremely well optimized settings for the printer. Some other printers with CF filaments are getting close, but not as good.

The only FDM printer i have seen with better surface finish than the Mark Two, is the Markforged X7 running 50 micron layer height :-)

It better be a very tiny part running 50 micron layer height. I print most of my stuff at 320 microns because I have a 330 cubic print area and I only print small. If I ever print big I am going to an 800 micron nozzle and print around 400 or 500 micron layer heights. Even then my electricity here is too unstable to risk any prints over 8h.

Yes, you would not use the 50 micron setting unless your part demanded it, the standard setting on the X7 is to print with 100 microns without and 125 microns with fiber reiniforcement. We regularly run prints that takes a few days or even a week if we need it to have a good finish. On the other hand, our power situation is quite a bit different, with Sweden having one of the worlds most stable power grids, with on average of 1.2 power failures per customer and year. And these failures are mostly on the countryside with trees falling over powerlines and such, in our office (which is in the centre of the capital) i don't think we have had a single power failure this year.

That's silly, you can do it with an old toaster oven just fine.

I dont mean to be so off topic but does anybody know of a way to log back into an Instagram account..? I was dumb forgot the password. I love any tricks you can give me.

@Sergio Lucas instablaster :)

@Graysen Santiago Thanks for your reply. I got to the site on google and Im in the hacking process atm. Looks like it's gonna take a while so I will get back to you later when my account password hopefully is recovered.

@Graysen Santiago It did the trick and I finally got access to my account again. I am so happy! Thank you so much, you saved my account !

@Sergio Lucas You are welcome xD

thanks i was actualy considering buying this

Anonymouspock It's certainly expensive to buy and to feed, but with MF I feel like they're using the profits to fund the research into next year's model which will be even better. Stratasys seen happy to sell the same thing for a decade.

That’s just normal priced prints, if you calculate overhead, machine and machinist cost in you will be way above that price for one offs.

A Machinist to run a printer? Hell, I go to work 40 hours a week programming cnc's, my printer stays home printing.

Graydon Treude i remember that too

One of his hires got them into it.

You should be getting that quality out of a Prusa. If you want to get rid of the layer lines, purchase a hardened steel nozzle and some CF filled filament, and you will have the same result. There will probably be a bit of tweaking and testing to get it to print super perfect, but I'd suggest taking the filament manufacturer's suggested settings, printing some stuff and revising appropriately.

You can print with the Onyx chopped fiber reinforced material witgout laying in the carbon fiber stands on a Mark Two. You can also print in Nylon 6 un-reinforced for maximum value when it's properties are acceptable for the application.

@@jamesg8246 , what would be the reduction of costs when using onyx for the same part in the video? 50% less? And what if not using any reinforcement at all? 70% less? More: parts without reinf. are brittle? In other words, they can be compared to the ones produced by an hobbyst-cheap machine?

From the movie "Short Circuit" and its sequels.

Johnny 5 need more input.

You're kidding, right?

Google MarkForged instead - might get the right hit then. ;)

*More like Aluminum is only a bit better than plastic. Sorry, I have only worked with Steel and Stainless. This is all hyperbole and every material needs to be evaluated for each individual project. I bought my first 3D printer when I found out that I could print nylon gears.

What about FDM plastics printed with thousands of interfaces. Only one layer needs to fail and the part is failed. Yes, plastics are strong. 3d printed plastics, not so much.

Speaking in very general terms; With so many things in our lives tracked and controlled by computers, any kind of "failed layer" brings disaster. The failed layer can be a glitch in our computer banking, a cycle in our computer controlled automobile engine, a bad line of G-Code running my CNC Machine. Most hobby 3D printers do not adequately control all the variables which can cause failures. These are mostly mechanical or electrical in nature. A full understanding of the process is what gives reliability, not dogmatic adherence to generalities.

JohnHoranzy Okay, but that wasnt the question. Even in a perfect case scenario, this is still fdm printing. There will still be layers of material.

Much of the metal in your world is held together with fusion deposited welds. The base material breaks before the weld. I will say that RU-vid educated hobbyists using hobby level printers with unheated and open build chambers are prone to printing objects that are weak along the Z axis. There is so much bad information on RU-vid and it gets repeated.

lol happens to me all the time!

Great vids btw. Love this channel.

Antonio Zavala I don't get the obsession people seem to have with printing firearms. When you have a full machine shop you can make whatever sort of firearm you want without the risk of blowing your face off by making it out of layered plastic. Having a 3d printer doesn't change anything when it comes to arms manufacture, not about the materials you would want to use and not about the licenses you need to make the endeavor lawful. The only thing it might change would be prototyping to check fitup before using metal or injection moulded fibre reinforced plastics to make production parts, just like for any other type of product.

Steven Doesburg who said anything about "firearms" specifically. Printing is great for prototypes. And shit just doesn't blow up unless there is a miscalculation in a certain application

You are correct, I assumed you were talking about firearms. I don't see what other weaponry you might try to make out of plastics other than say blunt impact weapons, hence my assumption. You are also correct that when designed properly the part should not fail. The challenge with FDM is that the scatter on the strength of the material from one layer to another is higher than the scatter associated with the bulk material. The achieved strength depends on the exact parameter values used during the printing. This makes it hard to produce parts with a controlled strength. The design allowables become rather low compared to bulk material if you want to be sure that the part will not fail. Using injection moulded fibre reinforced parts allows for much higher stresses in the part compared to FDM parts both because of comparably favourable fibre orientations and because the process is much more controlled. If this is not economically feasible due to the part quantity it might be better to machine the parts out of billet material rather than printing them. You could also turn to Selective Laser Sintering metals but then we are talking about an entirely different class of machine.

Or what? You gonna pound your little fists and stamps yer leetle feets and hold yer breath until you pass out? Can I watch? lol

Not even the trumpflakes know sarcasm when they see it

John's not stupid enough to "make" something that might blow up in your hand after a few shots...

Diesel Ramcharger it a showcase of how much strength those pieces are, not for showing how cute look.

True that Ouija. More awesome education content the better. Plus the new microphone and recording sounds way better then the last video with Ed
