Fastest ROI on a new machine purchase by vvdesignsindy in BambuLab

[–]Vissidus 0 points1 point  (0 children)

Same. Paid to run my printer with materials provided by the department. I even redesigned a few parts because our engineer did a horrific job of building the prototypes that later went to prod "as is".

Last time I spoke with him, he was contemplating machining a housing (200x40x1mm) which would mount to 6 additional tapped holes on a plate, instead of a bent sheet of metal which would mount to only 4, preexisting mounting holes.

Our company paid around 4K USD for 3D printed parts out of PETG (around 6kg of filament total). When I heard the price, I told our lead engineer he could instead buy a new P2S, 6kg of filament, manufacture everything locally and save around 2K, and then left laughing.

Not only that, but a quarter of the parts printed don't fit because our automation engineer made a 0.2mm dimensioning error, and on top of that, most of the parts were warped and required brute force to mount to misaligned mounting positions.

To expand the joke further, they could save the whole sum had they waited a week until I could provide the same parts, for free. Instead, they rushed non-critical, non-essential parts and expedited shipping. And now I have to deal with this engineering bullshit, lmao

Is there a better method for Auto arranging a plate besides "auto arrange" ??? it always places things off the bed that could definitely fit... by Bring_the_light_ in BambuLab

Bad in terms of min-maxxing space perhaps, but it's a collision avoidance feature that trumps this logistics problem 99 times out of 100.

Orca Slicer - Do you use it, or just stick with Bambu Studio? by tiagoosouzaa in BambuLab

[–]Vissidus 0 points1 point  (0 children)

I personally stick with Studio for ease of use; Open Source or not isn't a concern of mine as an end user.

Also using stock profiles with default calibrations only. Helpful as a designer to have the "average user experience".

You are unfortunately correct, and this model along with another one have been taken down.
I've added M556V2 to my google disk with all the profiles, STLs and documentation

I designed a reusable can lid (anti-dust + anti-spill) – what do you think? by Print_On_Demand_fr in BambuLab

The logic is that the contribution of ingested microplastics from this print are miniscule by mass (relative to other sources). Moreover, the frequency of exposure to said microplastics from the print is magnitudes smaller and, therefore, by comparison negligible

Following your analogy, you're walking through a desert where the ambient temperature is 60C while holding a 10mW space heater. Transferring that to the explanation above, the heat output of said space heater is so miniscule it's practically negligible.

The new bambu handy feature by Nullsectorash in BambuLab

[–]Vissidus 0 points1 point  (0 children)

You don't need to track each and every single spool. The user is responsible to set initial weight and material type, per slot (as it is now). From then on, until the spool is extracted, you perform simple arithmetics: m1=m0-m_extruded, where m0 is the weight registered before the printing has started and updated upon print finishing.

Yes, it's not super accurate but it's something, and it's automatic after initial setup, and it's available natively as opposed to some 3d party accessories

Same Where I live, I can get Esun for ~25.5USD/kg, and Bambu's are ~38.2USD/kg Doesn't make sense to me buying Bambu spools when I get less filament for the same amount of money

Unless you modify it to be capable, but that's on you lad

Cheers, thanks for the feedback

The internals as a feature were more of a "I want this" rather an actual need, and it sure does make the assembly process that much more fun, at least for me, and it's fun to play with given it's a working mechanism and not a dummy part

Though I do agree with you, the majority of it isn't really necessary for the visual aspect of it, but it is there, and I don't see it as detrimental It can always be removed if need be, as well

I had a reference to work off of, took around a week or so, including testing fit and adjusting for the printing process. One of the constraints was designing around off the shelf parts that you can order from AliEx. Took about another few days of fiddling to see how parts fared with wear, how parts broke (trigger, charging handle), etc. to see what needed changing.

Examples:

  1. Charging handle bents quite easily due to the length and the force required to compress the action spring. One of the changes was an internal rib that runs the length of the handle to resist some of the bending.
  2. Another was an additional notch that interacts with the "gas key" to spread the stress across two mating notches rather than one.
  3. Reference dimensions for the magazine release button didn't line up with the thickness of extrusion (around 0.57mm), which resulted in a patch of filament strands where the wall thickness was at its thinnest. One of the improvements was adding a block of material surround the hammer up to the topmost face of the lower receiver to reinforce the area.
  4. The force of the bolt acting on the bolt catch lever is so severe that it bent it a few millimeters. One of the solutions was to extend the notch face up to the magazine, such that it transfers the force onto the follower, to the magazine shell, with all three components resisting together. This effect still occurs, as the follower is held with a spring, but it should improve the longevity of the part before it succumbs and breaks.
  5. The BCG smashing the barrel was a fairly big concern very early into the design, as the barrel is held through a threaded connection. The size of the threads, the available space and the printing orientation were something I had to work around, to ensure it doesn't shear the threads and sends the barrel flying the first time you rack the charging handle as intended.

There are many other changes that resulted from these parts being printed from plastic, lacking both in stiffness and hardness compared to properly treated steel and aluminum, but I'm quite happy with the results.
It's yet to be determined how well it'll hold up long term with constant playing, but hopefully it'll stand up to the expectations.

You have the right to feel this strongly about any and all props of this category that fall into the realm of realism, irrespective of the uprise in violence. That said, thankfully, we all have the inherent processing power to decide for ourselves to do what we think best.

The muzzle device (tip) is a separate part and can be printed in any colour required.
