You are wrong. Let me put it like this. I said the A1 mini takes “about 17m” to do a regular .2 benchie. My estimate was only 3m off. My A1 mini can do a benchie in 20m exactly. It does a good speed benchie in exactly 17m.
If you think the A series takes 42m to do a benchie, you are wrong. Do you have an a series?
CNC Kitchen did had the h2d do the .2 benchy and it came out to exactly 47m.
CNC Kitchen did had the h2d do the speed benchie and it came to a poor quality at 23m.
Others also did the benchie on the h2d and regardless of exact numbers it takes over 40 min!
I remember when I bought my mini and all the people way up in praises that it could do a benchie in around 20 min. I’m looking at my screen right now it does a benchie from startup to finish in 20m. They were not praising a fast benchie at 42min that is twice as slow. The Prusa One takes even longer around 54m for a benchie. That’s just ludicrous.
Not sure what you are looking at on your screen, but Im talking about stock 0.20mm profiles on both machines. Its a bit faster with Bambu PLA Basic but still around 40 min. Im sure you can push the A1M to faster speeds as its got a lighter moving mass, but thats not what I was referring to.
Somehow my post got deleted. I’m looking at the screen of the machine. I have an a1 mini in front of me. The official 3d Benchy by Creative Tools which comes on the sd card. I don’t know where you got that 3d benchy or why it is slicing at over 40m but I am talking about the defaults on the machine. I’m talking real world.
Google how long an a series takes to print a benchy and you will get around 20 min I mean this is something practically every 3d enthusiast knew and praised like crazy. It’s not a secret by any means and 0.2 layer is a standard quality setting its nothing difficult or special. So why does the H2D take 47m to print the benchy? The Prusa One takes even longer.
Thats an official #3DBenchy, feel free to go to creative tools and download it and slice it yourself. FYI the one on the SD card is a super optimized pre-sliced one with a bunch of shortcuts, wider extrusion lines etc (would not qualify for the speed boat race either). Again you have to compare apples to apples if we talking speed comparisons. Bottom line is all of the Bambu printers in the lineup print at a very similar speed to each other.
The crux of it is this, my mini Prints a good looking benchie at 20min. It’s not missing any parts. It’s beautiful. The H2D takes 47m to print something that looks the same. The h2d speed benchy prints at 23m and its ugly.
I’m not buying the H2d until I can see it print a nice benchy in 20 min. I don’t care how its cut. I don’t want to see it on a slicer i want to see it in a real world test. How can you compare apples to apples on the slicer. Don’t make sense to me especially how the settings are right now. Real world results is where I am at. The h2d has a new settings so the slicing isn’t even exactly comparable to a different machine.
When the h2d can print a benchy as beautiful as my a1m in 20m I’ll buy one. I don’t care how it’s sliced.
I have an a1m and a P1S with 2 AMS and I’ve been waiting for the H2D for over a year. Was a bit disappointed at first. Been going back and forth whether to buy the H2D and the only thing holding me back from buying it is the speed. Seems like sometimes it is faster and sometimes it is not. Obvious there are certain color situations that are way faster that I know and understand. Taking 47m to print a benchy just seems so slow to me no matter how its sliced.
The H2D is a little slower, than the P1 and X1 series for some things, but not 20 mins slower for a benchy. Maxmit is right, you are comparing apples to oranges. You have to compare the normal benchy to normal benchy or pre-sliced-hotrod cheating benchies to each other.
The H2D hot-rod benchy is also 20mins (from the preloaded file). But if you slice it normally, with normal layer heights and normal line widths at modest 100% consistent speeds, you’re gonna find it and most printers still take 40+ minutes.
Even the VzBot 235mm (with 50,000mm/s2 acceleration and 2000mm/sec speeds) still takes 39 minutes for a basic profile “real” benchy. But make no mistake, that can be done much faster too if you tweak the line widths, walls, floors, speeds, and layer heights. I’ve seen sub 8 minutes benchies from that machine when tweaked. You simply can’t compare speed benchy settings to default profile benchies.
I understand where he is coming from. He is probably wondering why the hand tuned benchy off comparable quality and speed wasn’t released on day 1 like all the other printers. Its absence is creating doubt rather than reassurance if it were there. He’s from Missouri.
Is that a fair restatement?
Nobody trusts written specs. It’s no surprise. By hook or by crook, that benchy has become the proof test.
The explanations were well written though. Good reading.
Is this in reference to the H2D? If so, maybe it’s just a misunderstanding. The H2D shipped with a 20-minute speed benchy, just like the X1/P1/A1 series printers.
However, there was an unintended bug in the H2D’s speed benchy. For those that bought the HF Nozzle (which is largely useless for speed), the pre-sliced benchy won’t load. Basically, it cites an incompatible hardware profile (High Flow nozzle installed vs sliced for standard nozzle). I can’t run the 20-minute benchy on the machine as they sliced it without swapping out the HF nozzles for the standards. Seems odd, since an HF nozzle can easily run slower with no degradation.
This brings up the HF v Standard nozzle issue. I would have expected the high flow nozzle to give a tangible improvement in speed, but I’m not seeing that. It may help in cosmetic consistency of the extrusion and layer bonding but seems like there are no speed improvements (or at least no significant speed improvements). It’s difficult to simulate but you have to make sure the slicer is using the settings you set on the nozzle you are expected to use, and the filament profile is set to the high flow nozzle (not sure why this isn’t always automatic). So, for anyone looking to check for themselves, there is a lot of check and confirmations you need to do in the slicer (not automatic).
I’m traveling at the moment or I would run the test to answer this question, but how does the quality of the 20 minute H2D benchy compare? If the same, then i think we’ve answered his question quite completely.
At the end of the day the H2D is NOT marketed toward benchy speed demons. It is marketed for accuracy (vision encoder) and ability to print complex parts with dedicated supports from engineering materials ABS/PAHT/PPA/PPS.
Yes it is bigger than X1/P1 but that is really not the main point but a side effect of the dual nozzles. As a printer gets bigger and you have more moving mass, speeds come down as a result, its just physics. Expecting a larger printer to be faster is what “doesn’t make sense to me” if I can quote you.
I am the target audience for the H2D, and I could not care less how long a benchy takes even if it was 1 hour. As long as its faster/better with dual material use and able to produce dimensionally accurate functional parts. It ticks all the boxes for me: heated chamber, air filtration, dual nozzles, HF hot ends, 350c temp etc.
You want a fast big printer? Get an FLSun S1 Pro. Its bad at dimensional accuracy but if you dont care about that and want a faster benchy thats your printer.
I sent a model I’m working on and have printed on the P1P with Orca to the H2D with Bambu Studio 2 and was surprised to see the H2D take way longer. I thought it was Bambu Studio but checked a few models until I noticed the lack of print quality presets and knew what was up. I was just so excited to run the new machine I didn’t notice.
No the 23m speed benchy does not print as good as the normal 20m benchy does on an a series. The speed benchie on an a series is 17m and its comparable or better than the h2d sample i saw.
But anyways I am not talking about the speed benchy versions. I am talking about the normal benchy of comparable visual quality. It takes twice as long to print on the H2D
You are saying you don’t care about speed, only quality. That sounds like what Prusa and Prusa fans said when Bambu came along and proved that it could do prints with both speed and accuracy.
You don’t care if a benchy takes an hour as long as it is accurate? Well maybe you have plenty of time on your hands. I don’t know your reasons for purchase. I don’t have all the time in the world and buying the H2D would be for my business. It’s a $2000 machine. I can’t wait double the time and more for parts to come out of the machine. For me it’s for my business. I sell printed parts. You say to go to FL sun for faster and worse parts. Why do I need to do that when I have Bambu printers that can prints fast and beautifully? I am just expanding my operation to a third printer. But if the H2D is slow how much slower is it on a 1 color print? If its too slow then it’s going to have to be an X1C or a Creality K2plus.
Time is money and Bambu proved they can get prints done fast and accurate on the a, p, and x series printers. It’s a shame if the H2D at its price point steers away from that speed and quality.
Fist it was “When the h2d can print a benchy as beautiful as my a1m in 20m I’ll buy one.”
Then it was “But if the H2D is slow how much slower is it on a 1 color print? If its too slow then it’s going to have to be an X1C or a Creality K2plus.”
Which one is it? You want a fast pre-sliced cheater benchy or you want real world results? Those are two very different things.
It all depends on the item, but on real world 1 color prints in general the H2D is virtually identical to the X1, and if its slower it is by a tiny amount due to 8k vs 10k acceleration, all other speeds are virtually identical on “standard” profiles. With HF hot ends installed and HF filament with good max volumetric flow it can be a bit faster than X1 on large prints with lots of infill and long extrusion lines as it can do infill at 600mm/s vs 330mm/s on the X1.
I believe the K2 Plus will be faster, I wish you luck if you go that route.
Well what I mean is I can deal with it if its a little slower on single color because multicolor is faster especially if its just 2 colors. I do a lot of multicolor that stays under 20 filament swaps because the way I design the model.
Tomorrow is April 8th reorder day, and I still don’t know. I really like the Bambu ecosystem so I’m trying to stay with it.
There are no other printers on the market as reliable as bambu and Ive been printing for years and owned many other brands. No other brands have their own printer firmware, they are all using Klipper. I have 8000 hours on my machines and except for a couple of problems that were easy to fix (with parts that are very affordable), its been mostly smooth sailing. H2D is not a proven machine yet, but bambu has earned my trust that why i ordered one as soon as it dropped.
I would not give creality my money again. Just go to youtube and search for “K2 problems” to get an idea of what involved with owning one.
As long as its faster/better with dual material use and able to produce dimensionally accurate functional parts. It ticks all the boxes for me: heated chamber, air filtration, dual nozzles, HF hot ends, 350c temp etc.
I think this is the biggest thing for the H2D. Not every car is a sports car. A speed boost compared to other machines would have been nice, but I can appreciate a design focused on printing the difficult filaments that can’t be printed in any of their other machines.
Back to the speed difference: Has someone managed to get an apples to apples hands on test?Was it some kind of software bug or badly configured profile?
if we talking speed comparisons. Bottom line is all of the Bambu printers in the lineup print at a very similar speed to each other.
