A Hot End And Material Database For 3D Printing

https://fed.brid.gy/r/https://hackaday.com/2026/08/18/a-hot-end-and-material-database-for-3d-printing/

I've been 3D-printing for around five and a half years. So I'm not a rookie, but I just made a #rookie #mistake.

I've spent the last couple of weeks making compartments and dividers and such for the toolboxes I take to the Repair Cafe. Lots of test #prints to check fits and footprints, full prints, changes to design based on lessons learned during use at the last cafe, etc. I've put around three kilograms of #filament through my printer in that time.

Then, in the last couple days, I started having various problems. At first they only showed up on big prints - #adhesion and #curling, which I've had before when pushing the limits of my bed size. But prints seemed to be getting #sloppier, and I had a couple of spaghetti explosions.

Tonight, I finally took the #hotend apart and looked at it closely - it's very difficult to do when the printer is fully assembled, because it's a #delta printer.

Lo and behold, the nozzle appeared worn. And that can account for all the problems.

I should have checked this sooner - but I've only been printing plain #PLA, nothing abrasive, so I didn't think of it. Lesson learned.

Pardon the shitty photo from a cheap digital magnifier. The old #nozzle #orifice is about 1.5x the diameter of the new one - so 2.25x the area. No wonder plastic was going everywhere but where it should go!

Seems to be printing *much* better with a new nozzle.

Slow hotend reaction time and slicer/firmware not ready to compensate the speed and temperature is what takes me a step back on all this fast 3d printing hypes. This tech is promising and would make fast 3D printing compatible with quality and strong layer bonding.

However, the road might be long as it's blocked by patents and the software side might be very dependant on the hardware (so we would need reliable automatic calibration). 1/2

Dear #Makers and #3DPrinting nerds, I'm looking for opinions. As I'm about to upgrade the #hotend/#heatblock of my #Prusa i3 Mk3S+ and have a favourite, I'd like to hear what you think! Have you upgraded your #3DPrinter and have some thoughts, or looking for an upgrade? What is your experience?

#Boosts are welcome!

#hotend und #nozzle vom 3D-Drucker reinigen ist kein Spaß ...

Looks like I'll be having a #hotend upgrade/refresh, either I want it or not. #fml

Remember kids, never leave your #3DPrinter unattended. That's my free #3DPrinting tip for you today.

How is this #hotend supposed to work efficiently?
1. The heatbreak is assembled inside the heatsink which creates a warmer environment for it (no fesh air)
2. The hot block is bolted to the heatsink which is again warming up the surrounding of the heatbreak
3. There is a lot of mass between the fins and the heatbreak tube. Ideally you want fins and airflow as close as possible to the heatbreak
4. As usual no recommended fan specs, what did they use for testing then?

So the upgrade is installed, the bed is releveled and the first testprint is done.
So far no leaking or any other problems with the new nozzle/hotend 😁 Now let's do a Calidragon and check how that will go 🧐

Got a massive clog on my ender 2 machine which requires me to disassemble the whole hot end 🙈 perfect timing to switch to an all-metal one 😁 The parts should arrive today. Looking forward to fix this dude 😎

Well, that was close...

Was printing two items in #byobject mode. First one was doing well so I decided to go grocery shopping and check remotely from time to time. Obviously I forgot about that and when I remembered, the print was about 50% into the second item but nothing on the build plate. 🙈 I cancelled it remotely, but of course was worried about the desaster on the #hotend.
#Lucky me, it was relatively easy to remove.

Don't leave your first layer unsupervised. 😅

One thing that is rarely tested is that the faster you print, the weaker the layer adhesion. I'm pleased to finally see a video demonstrating this problem. These tests are only made with PLA and a single hotend, but it is a great start to see how quickly it can drop.

One of the most interesting 3D printing tech video I have seen in a while. Building an extruder isn't just about push force and weight, it is a lot more complex. To the point it is really difficult to make an in depth review. We can see how advanced E3D is in their R&D. Also, some good questions from Stefan and Tom.

Hm, wie druckt man diese Luftnummer? Die Brücke (blaue Linien), machen einen Bogen.

Mit normalem Support unmöglich zu erreichen.

Tree-Support windet sich durch die Gänge, aber wie bekomme ich das wieder raus?

Hat jemand den Umbausatz für #Creality Ender 3 S1 pro auf den #Spider #Hotend schon gemacht?
