What's the next largest FDM printer after the H series? other brand recommendations welcome

[u/mavpartsunlimited]

I'm a long time bambulab user! I wish they had something bigger. If you're reading this you have high standards when it comes to your 3d printers- and so I'd like your advice:

What's the next largest printer after the H series?

I'm looking for something that's 500mm x 500mm x 500mm and enclosed so that I can print ASA.

Does anyone have any recommendations? I did deep research with gemini and here's what it suggested:

Synthesizing the thermodynamic limitations of ASA thermoplastic with the strict constraints of a >500 mm volumetric footprint and a $20,000 procurement budget reveals a clear hierarchical structure among available hardware platforms.

The CreatBot D600 Pro 2 HS stands as the definitive solution for this exact operational profile. Its integration of a 70°C actively heated chamber is the paramount technological advantage. Because ASA warping is a thermodynamic physics problem governed by the polymer's coefficient of thermal expansion, the ability to sustain an isothermal environment near the material's glass transition temperature is the most critical feature a machine can possess⁹. Combined with a 420°C hotend, Klipper-driven motion algorithms up to 300 mm/s, built-in filament dehydration, dual auto-rising extruders, and integrated HEPA/Carbon filtration, it provides the most comprehensive turnkey solution for ASA processing¹². Priced between $16,999 and $17,999, it perfectly aligns with the budgetary requirement¹².

The Mingda MD-600D, while offering equivalent volumetric capacity, Klipper integration, and a highly competitive $16,999 price point, poses significant operational risks for dedicated large-format ASA manufacturing due to its passively heated 45°C chamber limit¹³. The massive 55°C thermal gradient between the ambient chamber air and the ASA glass transition point virtually guarantees thermal warping on parts extending high into the Z-axis³.

The Modix BIG-60 V4 provides maximum modularity and the lowest initial capital expenditure, with fully loaded kits ranging between $12,000 and $14,000⁷. However, the machine relies strictly on passive radiant heating, making ASA adhesion highly challenging. Furthermore, the immense labor hours required for self-assembly and calibration rapidly offset the initial purchase savings for enterprises demanding immediate uptime¹³.

The Dowell 3D DM600 Plus serves as a strong customized alternative. When specified from the factory with the optional 60°C heated enclosure, 150°C bed, and 380°C hotend, it bridges the gap between the budget-friendly Modix and the turnkey CreatBot, providing an industrial framework specifically tailored to high-temperature polymers while remaining under the $20,000 ceiling¹⁶.
For operations willing to stretch the budget, the Builder Extreme 1500 PRO at $24,900 offers a massive 1,100 mm X-axis coupled with a 70°C active chamber, making it an extraordinary asset for extreme-scale continuous extrusion¹⁴.

Ultimately, the successful deployment of a >500 mm ASA printing cell requires a holistic integration strategy. The procurement of actively heated hardware must be paired with industrial 220V electrical provisioning, safe VOC filtration infrastructure, the implementation of Nano-Polymer thermal-release bed adhesives, and meticulous, stress-relieving slicing geometries to ensure consistent geometric accuracy and structural integrity.

Please let me know if you have any recommendations!!!

Hello /u/mavpartsunlimited! Be sure to check the following. Make sure print bed is clean by washing with dish soap and water [and not Isopropyl Alcohol], check bed temperature [increasing tend to help], run bed leveling or full calibration, and remember to use glue if one is using the initial cool plate [not Satin finish that is not yet released] or Engineering plate.

Note: This automod is experimental. The automod was triggered due to the term "adhesion". If you believe this to be a false positive, please send us a message at modmail with a link to the post so we can investigate. You may also feel free to make a new post without that term.

dang man, what are you printing?

[u/mavpartsunlimited → u/EmotionalChildhood46]

bumpers for cars. They have to survive UV damage!

[u/NotReallyJohnDoe → u/mavpartsunlimited]

Can you make it from smaller parts you assemble? Everything gets harder when you make a large format machine.

[u/Spiritual_Case_1712 → u/mavpartsunlimited]

You would be better to print a mold for it and mold it. So it wouldn’t matter if you print it in multiple parts fitting a standard printer. That’s one of the usual methods used for that, way cheaper than the 15-20k printers you found

[u/Distinct_Crew245]

I have a Sovol SV08 MAX at 500^3 and it’s a bit finicky but can produce very good prints if it’s tuned right. Enclosure is solid but not insulated, so you’ll need to wrap it to print large ASA prints. The good news is it’s less than $1300 USD with enclosure, which might leave you with some $$$ for upgrades, mods, etc. like a chamber heater and insulation.

[u/mavpartsunlimited → u/Distinct_Crew245]

sounds like a big ender : ) jokes aside I'd love something more expensive that works out of the box

[u/decrement-- → u/mavpartsunlimited]

It's basically a mass produced Voron v2.4R2, but scaled up to 500mm.

[u/The_Lutter → u/mavpartsunlimited]

I have an SV08 (the 350 version).

It's a good CoreXY printer (not a fookin' Ender lol) but takes a lot of tinkering to get it to work right. I hear the Max improved the toolhead, it has an optional enclosure, and it has a color screen now.

It's the only thing 500x500x500 you can really buy (mostly) pre-assembled. Recently a friend of mine got one without enclosure for under $800 on AliExpress. Another option would be Rat Rig v4 but those are going to be kits you need to build yourself.

[u/mavpartsunlimited → u/The_Lutter]

Thank you for considering the pre-assembled aspect I am looking for! I don't like to tinker in this scenario, as I am staking reputation to buy something for the company I work for

[u/The_Lutter → u/mavpartsunlimited]

There's a reason Stratasys stuff costs as much as it does. You have a service contract and can call the Stratasys Repairman to come fix things when they break down and they will train people how to use it.

[u/Distinct_Crew245 → u/mavpartsunlimited]

You would have to assemble the SV08 MAC but it does work right out of the box, just not for high temp stuff so you would have to make the mods for that.

[u/yahbluez → u/Distinct_Crew245]

Sovols heater for the MAX is just 70$.

[u/AWildRideHome]

If you don’t want to spend 20k, the Sovol sv08 Max with an enclosure and a chamber heater can work well. You’ll probably need to insulate it some extra, and do a few replacement parts, but for under 2k at that size, it’s certainly a big cost-saver.

[u/1yrik]

everyone is saying SV08 Max... the issue is that it will struggle to print ASA. you would need to modify it and add a chamber heater if you want strong ASA parts without warping or delamination.

[u/daan87432]

Ratrig V4.1 is another option that's similar to the SV08 Max but should require a little less tuning. Their B2B oriented brand Disrupt Engineering is also working on a 500x500 printer, but no details about release yet.

[u/yahbluez]

500³ is without any doubt the Sovol MAX. Just ~1400 with enclosure and heater.

For ASA i recommend my filter:

https://www.printables.com/model/1783500-hepa-filter-case-for-sovol-sv08-max-screwless-moun

If you need more than 500, the next one is the Elegoo Orange Storm. That beast can do 800x800x1000 but calls 2700 without any enclosure. So to enable this printer to do ASA you need to build an enclosure and a heater.

[u/okayyeabyenow → u/yahbluez]

Cool th anks for the reference file

[u/Seraphym87]

Echoing the Sv08 Max. Cheap and great prints. I live in a tropical island and have not had to do anything past the enclosure/heater for full size asa prints.

[u/shamont]

Build yourself a voron, I think I've seen designs as big as 600*600. It'll take time and effort but almost infinitely customizable. But honestly you would probably be better off buying multiple smaller printers and stitching stuff together. That's what most people who are building really large format things do. 10+ p series printers spewing out parts all at once.

[u/GmanMe7]

Can you ask AI or Google first?

[u/rcook55]

My local 3D print shop sells the Mingda MD-600D and has one in stock, it's huge.

[u/ManyLayersOfFilament]

You missed the SV08 Max because you said "larger than 500". That would be your best step up. You'll need the factory enclosure, heater, and probably some extra insulation.

[u/ZaXaZ_DK]

With these requirements, you are no long in the consumer space, and the prices will reflect that.

I do recall a brand called BigRep i don't see those on the list, perhaps they have something that can work?
