Appreciated.. we need 4 of them.. trying to make it a teachable moment and get the kid exposed to CAD or at least a CAD like program. If he wants 'em, he can design 'em and print them off at the library.

ahh. tinkercad is a good one

The volume that you are cranking out is impressive! Is that about a days worth of printing?

8 hours each for them. each printer can knock out 3 a day assuming things are running well. Plenty of failures along the way. 7% is my factor currently.

These are part of a bi weekly batch so I spread them out between other jobs to not eat up the entire fleet. really nice jobs to run over night to keep printer rest time to a min.

thats about a weeks worth of filament. 1kg spool for reference on top there.

50ish KG a week is no small feat!
Always interesting to see how print farms are working, running the longer prints overnight makes complete sense too. Then the smaller prints can be run during the day when there is someone around to reset the printer.

Are you moving the whole farm to MN? or keeping some at home for prototyping?

How much scrap filament do you typically end up with? I'm not thinking about failed prints, rather the left over bits of filament from change overs, purging etc? Are you at a point where you could justify reprocessing the scrap?

I think about this a lot these days as my company is really thinking about the long term impact of all the plastic parts we produce. At least when dealing with scrap from molding the material type is well known so it does have value as regrind for uses where they are less concerned about the details of the materials.

The ideal is 2 prints a day. a short one and a long one.

This is an example of what I try to kick off for overnights: give a little lee way in start time but still plate is cold when 8am hits to manage.

very little left on spools. purge lines and poop really isn't much in the grand scheme of things for what we're doing. moving to 5kg spools so each printer might end up with 3 poops a week. purge lines i been meaning to change the start code to reduce the size. mainly cause the robot vacuum doesnt like the long ones.

spools themselves are a giant pain. not sure if shredding and running a recycling line would make sense. I'd rather end up just having my own filament production line and use the spools in a loop.

Spools do seem to be the biggest waste in 3d printing. Hopefully reusable spools and filament refills start becoming more the norm, not a fan of cardboard spools really.

Of course if you are big enough to justify a filament production line, then that would make good use of old spools.

I wounder if you use enough to justify getting resin in pellet form then processing it into your own filament. A while ago we were discussing where the cross over points on cost were. I think pellet resin, the form we feed into high volume mold machines, is something like 1/10th the price of filament on a spool. At some point it seems like it would be cheaper to buy the machine that forms the filament. Of course, it needs to be a clear advantage to take on the risk of a new machine and learning curve.

I was curious and found this machine (never heard of them prior to my search) for $7500.
It claims it can produce 2lb (~1kg)/hr. Assuming $1 for pellets vs $10 for filament it saves $9 per kg of resin (ignoring operating cost which aren't free). So assume you use 90kg per week, it would save ~$800/week in material. So that would take about 10 weeks to pay for the machine. The machine would also have to run basically non-stop for 4 days to keep up with demand. I could see it paying for itself in a year but I could also see complications that could really hurt that ROI estimate. If you run different filament types, have breakdowns, get lower quality output, if the dies wear out quickly.

Do you know if the big print farms extrude their own filament or perhaps get better prices from sources?

Better have a hell of a recycling agreement either way. Between the plastic, the spools, and the cardboard boxes, you'll need it. I thought more about the cardboard after your initial post than the plastics, but the above posts have good points. Im interested to see where you go with that.
Meanwhile on my one little measly printer I think about what to do with the dang boxes and some spools from my 1kg stuff. I am finding the boxes are nice for dividing and sorting hardware on active projects. They're disposable and seal up so they can't be dropped and dump out. They soak up oils, and are easy to write on (label). I do like that if one sticks to the Bambu system, you don't have all the extra spools at the end. You just buy the reloads. Its almost worth the shipping wait times in my opinion, for personal use of course. A business can't bother with that obviously.

refills are slowly making their way into market. I'm working with my china supplier to do just that. I hate paying for shipping of spools as its dead weight.

if I got into filament production it would need to be in the order of 20-30kg an hour production to justify.


you end up in the 10-20k range for the line.
1717773929725.png

plus 2 dryers:
1717773978531.png

then about a 1.50 a kg for raw PETG pellets in bulk.



But I'd need to sell filament as well which is a highly competitive market with minimal margins. I'd really just be doing it as a nonprofit to get better pricing on my supply to reduce my COG and maintain my own stockpile.


Maybe someday. until then i'm really happy with my under 7 a KG china suppliers.

i'd need to deal with it as well time wise. and run it 24/7. labor isnt free. so saving 800 a week in material gets burned by labor and then some.

15 printers. 1.2kg a day burn per printer. so I'd need two of them to maintain.

I'm working out 10kg reloads from china. which means designing my own spools for this style/concept. cardboard tube and strapped together.

Slowtwitch, I am happy to send some basic tutorial videos I made for teaching my students (OnShape). Walks them thru both some basic shapes, as well as slightly more complicated setup (90deg LB Conduit box). This was taught to 7th graders.
To be clear, I am happy to send them to anyone who wishes. I also have the same design videos for Solidworks as well.

Somebody who has a Prusa XL with the multi toolheads please chime in.

I have a need for multicolor TPU printing. I need the object to be flexible as it is worn as a hat, however I also need the lettering on said object to be semi-transparent. I have already picked my filaments but due to the bambu ams and the way it's configured theres no way I'm getting anywhere with that.

I'm curious if the multi toolheads on the prusa xl can handle this task. I'm currently working on getting my e3d toolchanger back up and running but trying to decide if it's worth it to buy the XL.

Hey guys.. I'm sure this has been answered numerous times, but here it goes again..

What's the best program to design a small part.. free and beginner friendly?

It's for a 24th scale RC truck wheel.. so about half dollar diameter, 1/2" or so thick.. a small cylinder essentially
with a hex on the back side.

Thanks.
Take a serious look at Microsoft 3D Builder. Cork sniffers will scoff at it but it’s stupid simple to use, very effective at achieving results and is a great introduction to conceptually understanding what you are trying to do from a design perspective. I have several patents from products I designed with it, and I’d bet if I had used my autodesk programs,I might not have completed those project.

its not the tool that counts, it’s the result.

I just took a look and I think I will try to show it to a few people (and kids). I've been a long time SW user but I've always wondered about a program that would be reasonably easy for people who don't have 3D modeling experience (and aren't used to thinking about how to build a model in parametric CAD). In particular it would be nice to have something that is reasonably easy for kids to use so they can successfully design then print something.

I know this is the 3D printer thread- but just reporting in on some more success with the Lowrider V3 CNC router that is mostly 3D printed. Attached is a stencil I cut with it this morning, I was able to use Fusion to make the design from the image file that Tesla has as their "Official" logo on their website. I think it worked pretty well. I'm currently struggling with making the machine do some carving, but it's not the machine, it's me and my Fusion abilities. I think I have it figured out, but just need to practice on some scrap.

Anyone have experience with the Flashforge Adventurer 5M? A friend is looking at getting one and asked me about it. I don't know but thought some here might know more than just want the YT videos show.

Speaking of PEI plate.....do they all scratch the coating off with the nozzle in a little spot in the very back of the plate before starting a print, or is it just mine?

I believe that's normal on the little tab at the back, my printer does it on all of the plates. From what I can see online, it's part of the nozzle cleaning process and is completely normal.

For single color prints that just need to work, I think the market will eventually trend towards pellet based 3D printers. I am still looking for an out of the box printer (at least 300x300x400) that can print ABS/ASA without any fuss (warping, lifting, etc.) I still use a CR10s in a hotbox, it's just slow and finicky at times.
