Gabby nailed the "Why did you come work for us" question. I would have said, "Cuz I was broke and you'd pay me!" But good episode and having a guest makes it more interesting being able to go back and forth. I think you should have a series where Gabby builds her own Voron.
Regarding TPU filament, I got my hands on some 98A hardness filament. The stuff is great! It’s somewhat pliable, but quite rigid when printed with solid infill and adequate thickness. I’ve used it to print a phone mount in my car, and it hasn’t warped like PLA and PETG have (I live in Central Florida). The filament itself has to be printed slowly, though. Even with the additional stiffness, it still binds up in standard extruders when printed quickly.
I know how much fun it is to try to manage/maintain multiple printers of different designs, however that's in a non-production/home environment. I recall that at one time Google was talking about their server reliability stats, with something like 20% of devices being offline at any given time (rough memory, might be 2%, but..) Mostly related to scheduled maintenance/replacement, but almost half of it was for hardware failures (board or drives. From a large 3d Print Farm perspective, what percentage of printers do you see as being down at any time is a good percentage? (All machines should have some scheduled maintenance, and I consider that part of this. Things like checking belt tension, making sure moving screws are properly lubricated, and associated things that affect end quality.) Then there are things like filament jams, hot end thermal failures, sensor failures. What sort of work are you doing to detect and remediate such things early. We know that a printer that's offline isn't making the company money. At the same time, monitoring and maintenance (generally in my view) when timed correctly, is very probably the easiest way to stay ahead of problems.
Hmm, I find that TPU is generally close to double the price of PLA, PETG or ABS. I also find that TPU tends to print slower than all of them and tends to be more hygroscopic or sensitive to moisture. I find that there's more trouble with stringing due to the sensitivity to moisture, more jams, and clogs and also more difficulty with build surface bonding (too much build plate adhesion on PEI). I'm using 95A but maybe these problems get better at higher durometers.
The algorithm showed me your channel. Off the top of my head I've learned a few things from it, one big one is how much injection moulding shapes how we think about plastic parts, when it isn't really a limitation of plastic, it is a limitation of the injection moulding process. You've reinforced some of the things I've learned in terms of CAD for 3D printing, as I only really CAD to repair or create things, and given me a bunch of ideas to help in future designs.
One question I have on tpu being a really great material is support material, as tpu generally fuses to support unless you use another material for support interface

I love you guys. So glad to have found your channel. Also Gabby seems to be excellent. I've got two questions. 1. What are some of the issues you have run into (or wish you knew going into this industry) on the topic of laws, regulations and such specific to starting a 3D printing business. 2. Any chance you would be willing to do a video really breaking down how to build one of your more recent revisions of the slant box? I know you guys revise them often and that you can't do revision videos all the time. But I'd love to see a recent one if possible. If not I absolutely understand. I'm in Texas and extremely interested in starting my own print farm/3d printing business, and these are currently my biggest questions. Thank you guys for all you do!
Thanks to both of you for a great video. I was wondering if you already have a video about what to due with scrap filament? I've got a 1/3 size blue recycle can I keep all of my filament waste in. Is there a place to recycle? Thank you.
Excited for the upcoming filament news. Personally, cost is a big factor for me, so those runs of purge would be pretty cool to purchase. Plus the variation in color can be interesting, even if unreproducible.
Since you take the step of building your own 3d printers i would assure you also developed your own software to run the farm. Do you see these two items as a potential product for you in the future? You said you would like to see more 3d print farms popping up and if these were available it would help and give you another market.
Great video and its nice to get to know more of the team. None of us are as strong as all of us. I look forward to getting to know the whole team as my designs get accepted into the market. Keep up the great info. 👍 🇺🇲
PETG prints well if you can understand basic slicer settings. It's really not that hard. PETG is also the ideal middle-ground filament when you want temperature resistance and tenacity, without moving up to something like polycarbonate. PLA is great for non-technical parts and other trinkets.
A request and a question: I'd like to see that robot arm toy. Q: what are people talking about when they say you want to minimize the surface area when 3D printing? Do they mean the amount of the plate that the base of the project takes up? Because the 3D printing that I've seen seems to tend to maximize the surface area by having lots of hexagons internal rather than it being a solid mass for example
Could you expand more on TPU, for mass production applications and the challenges it has, how to overcome them design-wise or just printing setup (ejection of the printplate ...), maybe a possible product design example. love this channel, and how it changed how i approach designing for 3d printing
Great video as always! I would love to here your point of view on manufacture at point of use (eg, making parts on a ship/plane/local mechanic/etc), you kind of touched on it in your future of mass manufacturing 3D printing and environmental impact. Great video as always!
Can you recomend book(s) on design for 3d printing? I have years of traditional manufacturing experience. It is time to embrace the new reality. Your videos are great.
Love the ‘guest’! Man… so much win. This channel rocks. I’m starting a print farm (probably) and I consider your channel an invaluable resource. I highly appreciate the time and effort you put into this and your work!
The thing about recycling PLA for instance, is that you have to mix it with about 50% virgin beads, as remelted plastic will lose a lot of its valuable properties. There are a few businesses out there that have dabbled in recycling and most are in Europe, where waste is heavily taxed. As far as I understand, these businesses are viable but only because of the taxing, ie. since printers have to track their waste and reduce it, or pay taxes for the disposal, it creates an opportunity for a recycling business. The recycling by itself appears to cost more than you'd get from selling recycled filament alone. I have a feeling a lot of that has to do with how complex it would be to control the properties of the resulting filament. Not all PLA is created equal, and you have no control over the source material when recycling, so you'll end up with some of the worse quality filament out there which will be a very poor value proposition for most consumers, forcing you to sell those rolls for a very low price.
This depends on the region of the globe. In Europe and Asia recycling is integrated into the general regional infrastructure. (deposit fees, and taxes to discourage waste) For North America this is not the case, and most post-consumer items are considered landfill waste. Of note, PLA is a corn-starch bio-based material. While other filaments are have different origins, it's the system around the material that makes recycling viable. For example for copper and aluminum, a larger percentage of that used in new manufacturing these days is recycled metal, not virgin mined material from the Earth.
Tripteron, it took me a while to figure out that was what you were trying to say. I like your videos, but sometimes I find it hard to hear what you say. About tripteron, it should reasonably be pronounced as a scientific name, as it, like most scientific names, is based on Greek, and it means "three winged". The tri-part means three, the p belongs to the pteron part of the word that refers to wings, and the p is more or less silent in English, more silent in American English.
I'm actually going to build my own 3d printing farm and your company is an inspiration, what technical suggestions do you have for me to prevent problems you had through this journey? I am Tohid by the way :D
That description of the STL format is completely wrong 😂 There are no "very small pyramids, like pixels" in there. STL files encode regular meshes as polygonal data (surface tessellations), just like most other 3D file format. The 3D surfaces (and surfaces only, no volumes) are basically encoded as a lot of triangles. The triangles are not necessarily small either. A large cube will literally be cut up into 12 large rectangle triangles, 2 for each face. I have a feeling you threw in this wrong information purposefully to generate engagement, because I doubt someone who works with 3D printers professionally really thinks STL files encode... pyramidal voxels? Anyway, great video otherwise!
Closer, but still not right. "Just like most other 3d file format" is wrong; specifically BREP solids, NURBS surfaces and Sub-d surfaces. No tesselated polygons involved in any of those geometry reps which are commonly used in 3D CAD.
I listen to the first three and a half minutes at. 5 playback speed. It was good information but I was about to quit because of how utterly Stoneed you both sound ed
How often you rant about people using 3D printing for things that shouldn't be 3D printed makes me now see how often people do that and I'm just like why. What are you doing? You got a 3D printer to do woodwork and then you complain about layer lines?😅

Different support settings and some changes to the material fix this.

How heat sensitive is PLA when left outside in the summer temps? Can a birdhouse take 100+ degrees temps for long?
There is no doubt whatsoever that Bambu Lab IS the best choice for a beginning inventor/entrepreneur designing new products.
Great video and its nice to get to know more of the team. None of us are as strong as all of us. I look forward to getting to know the whole team as my designs get accepted into the market. Keep up the great info. 👍 🇺🇲

Yeah, don't understand his hate for PETG. Way better heat resistance than PLA. I suspect their printers just can't print it reliably.
I am pretty new to 3d printing and after watching some of your design videos I have really improved my own designs. Thanks!
That was a nice change of pace!
Need a way to use your print on demain stuff for the Amazon sales model. Yes, there is the 'amazon tax', but etsy etc does that too.

TPU as a fantastic filament? Try using TPU with supports / so much stringing...
Great QnA, in an informative and fun format.

Yes more 3d print tech talk, and more Gabby.
Wow, no .3mf?

PLA also give off a almost as much emissions as ABS, it's just that ABS smells far worse.
You immediately lost me when you said ABS is horrible. Sorry, not sorry.
Yeah, different materials, different applications. Once my enclosed printer arrives, I'll print ABS exclusively
I think it was snoop Dogg that invented the g code lol
