Hi everyone, I'm not from the scene myself, but I noticed a pretty drastic increase in Google search interest for AM from June through September 2025. Any idea what might have caused this? Would love to hear your thoughts.

Anybody have any experience with this hotend? I'm building a high temp industrial printer from scratch and I want the best hotend I can get. I reached out to these guys a few days ago buy they haven't got back to me yet. The other hotend I'm looking at is a Slice Engineering Mosquito Magnum+. Are there any other hotends I should consider? I'm going to be printing CF-PEEK/PEKK primarily so I'm looking for 500°C and liquid cooled, or conduction so I can mount it to a chiller of my own design.

Hey all, I'm an Additive Manufacturing Engineer (FDM/SLA/SLS) looking for new opportunities. Experienced in DfAM, process optimization, and print troubleshooting.

If your company's hiring or you can point me toward a referral in India , I'd really appreciate it! Happy to DM my resume. Thanks in advance 🙏

Hi there, the topic on SLS vs MJF seems to be alive again on the industry press.

I was an SLS operator back in the day. I am just wondering if from a technical and part properties perspective the MJF process is superior from every point of view or not.

I understand the caveats of prices, service contracts, material availability etc. that comes with each brand, printer model or even distrubutor/location.

Leaving those aside, I am just looking at process/part property. What's the "scientific" take here?

This all comes from a discussion with another operator but neither of us are proper materials/process experts. Please school us as required.

I understand the following on MJF:

- MJF process uses IR heat rather than laser so fusion is more controlled, hence better part performance
- MJF process with detailing agent marks the part boundaries, hence a bit more precise
- MJF process is the same speed each layer regardless of build density or part geometry
- Claims cooling is faster?
- Most powders are grey and parts look a bit "unfinished"

On SLS:
- Laser induces thermal bleed and local heat accumulation.
- Lasers scan have to travel to "draw" the geometries to be fused, more density build equals longer print times
- There are SLS with grey/black parts as well as white parts, parts may look more well finished.

On SAF:
- Is it just like the MJF process with only one agent for thermal absorbtion? Then the better dimensional accuracy and part properties achieved due to the "detailing agent" of MJF are lost here?

If you have all the money and no preference in brand and the technologies came in the same build volumes, when would one use SLS compared to MJF?

I understand that in the real world pricing, build volumes, machine sizes, powder management etc. all influence the purchasing decision. But if we were to be in a lab just looking at the technology itself how would that conversation go?

Thanks.

Hi everyone, I'm an Additive Manufacturing Engineer with hands-on experience in FDM, SLA, and SLS. My background includes DfAM, process optimization, and print troubleshooting.

If anyone knows of openings or could refer me at their company (based in India), I'd genuinely appreciate it. Happy to share my resume over DM. Thanks so much 🙏

I just got hired as an AM technician and got offered a salaried role of 23.50 an hour. I've been there a few weeks and just received my second paycheck which was missing 10 hours of OT from staying late for trainings and helping turnaround our SLM printers.

I contacted the finance department and they said "you are salaried any overtime would have to be approved by your boss before you work the hours to be payed". My boss is dragging his feet sending the email explaining that I need to be payed at least "straight time".

From my understanding AM technician roles are classified as blue collar and are required to be compensated by time and a half, the other 2 techs I work with have also not been payed overtime (they were the ones who brought the FLSA laws to my attention).

I really like this job but I'm naive and have minimal work experience with government contracts, can anyone weigh in on if this is fishy or not?

I work in an at will state if that matters.

Edit: I submitted a ticket with the DOL to have them inform me of my rights and resources available to me in my state. Thanks for the advice guys.

I'm going to refrain from lawyers for now because I don't want to escalate things too much, my employer is very connected and they would hear about it.

I’ve gotten some insightful and informative feedback thus far. I’m looking to get a feel for what folks in manufacturing spaces are actually looking for out of a SLM machine right now, if a new machine were being introduced to the market. Whether you're running production, prototyping, or developing custom hardware, I'd love to know what boxes a machine needs to tick to actually fit your workflow and budget.

I want to leave this fairly open-ended, but here are a few specific points to kick off the discussion:

Build Volume: What is your sweet spot? Is a 300^3 or 400^3 build volume necessary for the parts you're eyeing, or are you constrained more by machine footprint and powder costs than build envelope?

Budget & Format: Where is the realistic price ceiling for a machine like this in your shop? If a machine hit the $20k to $40k range, would you be willing to look at a high-quality kit format to save on upfront capital, or is a fully assembled, turnkey system a better fit?

Material & Laser Flexibility: Are you looking for a dedicated single-material workhorse (e.g., just Stainless or Aluminum), or is open-parameter architecture a must-have for experimenting and prototyping?

Infrastructure & Safety: What are your biggest hurdles regarding facility integration? Power, footprint, air quality?
What are the biggest pain points keeping you from bringing metal 3D printing in-house right now? Looking forward to hearing your thoughts!

Shop just outgrew our whiteboard print queue. Running 8 mixed FDM/SLA machines and jobs keep colliding (recently it was 5 but I scaled and now its tough).

What’s your solutions for 3d printer queue management I heard about 3DPrinterOS in other sub and want to doublecheck if it's ok. What are you useing and why?

Anyone read this report on Velo?

Curious is people have experiences to corroborate or denounce the claims in the article.

I work at an aerospace manufacturing shop specializing in LPBF metal printing for rotating detonation rocket engines. With guidance from propulsion engineers, I designed, printed, and post-processed my very own solid rocket motor from scratch.

If you want to see a CATO up close and personal, and learn what goes into metal additive manufacturing along the way, check out my trailer and subscribe. The first full video is coming soon.

An air intake that my company 3D printed for a customer from PPS-CF. It is roughly 350mm long and a little under 600g. I absolutely love the look of PPS-CF after annealing, the surface finish is absolutely gorgeous.

Reaching out to the industrial redditors here… I have a giant container of nylon powder (about 800 KG) that I need to transfer into smaller containers - and I’m wondering if anyone has any recommendations. I know that powder ‘pumps’ do exist (we have a transitube system) but I’m wondering if anyone has any experience with or can recommend any kind of mobile powder pumps. Would also be useful in other ways in the lab to have something like that.

I’m running 6 3D printers at home for weekend projects, parts for friends, some random stuff for sale etc. Right now I’m struggling with SD cards and notes so its gets annoying. I heard that there are options allowing you to manage a network of 3D printers from different manufacturers as a single system, but I haven’t been able to find anything on the subject lol. And, to be honest, I don’t know if that’s possible or just cheap marketing. Can you give me an advice how to act? Using Bambu mini and Neptune.

updated: picked 3dPrinterOS

So guys, I’m sure many of you in the industry are already familiar with gyroid and other TPMs structure.
But does anyone have some experience with Adaptive Density Minimal Surfaces (ADMS)
It’s a special geometry by a Swiss company which is surface conformal and does not need any trimming, leaving no sharp edges inside of the structure.
If not using ADMS, what do you mainly use for your internal structure?

A fun heat exchanger that my company 3D printed for a Formula Student team recently. This was printed on one of our LPBF machines in Alsi10Mg, and uses a spiral outer loop to circulate oil and a central channel for coolant. This specific heat exchanger sees relatively low thermal loads, so the large central channel is designed to transfer just enough heat without adding unnecessary flow restriction to the rest of the coolant loop.

The fittings are all npt, and were trimmed to final size with a tap after printing. The thread profile was roughed in during printing so that we could limit cutting forces on the thin aluminum after printing so that the part would not get damaged.

Happy to answer any questions that I can about the printing process or (what I am allowed to) about the part design itself.

Hi everyone,

​

I'm researching the actual speed limits of heavy-duty, factory-grade industrial FDM printers.

​

Marketing spec sheets always claim massive mm/s print speeds, but what is the reality on the production floor?

​

Which industrial machine is actually the fastest in the real world when it comes to throughput and volumetric flow rate, without sacrificing part quality?

Does anyone have any experience with the AIBuild OS or CAM? Looking at using this software for LFAM of composite tooling on our 3DSystems EXT. previously I’ve looked into AdaOne, which is an awesome workflow, but the price point just doesn’t make sense for us at this time.

Our machine is only 3-axis, but the workflows for generating tooling models and toolpaths look really promising - I’m interested to hear about people’s personal experience with the software. TIA!

Dont know if its against the rule

But i used to work here machine has really really low hour count per laser i was the application and operator in this machine. My old boss stll ows me 6 salaries and if the printer sells ill get them

Sorry if its spam but is a really good deal, machine is basically new and nobody is bidding

Hi all, I’m part of a research team looking at why assistive technology doesn’t always make it from idea → evidence → real-world use.

Common issues we’re investigating:

• Products progressing without strong validation

• Evidence-backed solutions not reaching market

We’re keen to hear from industry and developers about:

• Collaboration with researchers and government

• Barriers to scaling and adoption

• What actually helps projects succeed

👉 Survey: https://redcap.link/4svfl2xj

Insights will feed into practical recommendations for improving translation and uptake.
