Three brands dominate the serious desktop 3D printing conversation today: Bambu Lab, Prusa, and Flashforge. We stock all three at Eolas Prints, so this comparison isn't about crowning one winner — each genuinely excels at different things. It's about matching the brand to what you value: ecosystem polish, openness and repairability, or capability per euro. Here's an honest breakdown. The Short Version Bambu Lab — the most polished, plug-and-play ecosystem, with the most refined multi-colour (AMS) experience. Best if you want it to just work out of the box. Prusa — open-source, endlessly repairable, EU-made, with legendary longevity and an upgrade path. Best if you value openness, serviceability, and a machine you can maintain for years. Flashforge — the value-and-capability choice: CoreXY speed, enclosures, multi-colour, and large-format options at noticeably lower prices. Best if you want the most printer for your budget. Bambu Lab: Polish and Ecosystem Bambu Lab earned its reputation by making fast, reliable CoreXY printing genuinely plug-and-play. The P1S sets up in around 15 minutes, prints quickly and cleanly, and its AMS multi-colour system is the most refined of its kind. The software and hardware are tightly integrated and well-polished. The trade-offs: it's a more closed ecosystem, and single-nozzle multi-colour (AMS) produces purge waste. If you want the smoothest possible turnkey experience and a top multi-colour system, Bambu is hard to beat. We supply genuine, 100% original Bambu Lab products. Explore the Bambu Lab range. Prusa: Open, Repairable, Built to Last Prusa takes the opposite philosophy: open-source, designed to be repaired and upgraded, and manufactured in the EU. The Core One is its fully-assembled enclosed CoreXY machine with active chamber temperature control and a genuine upgrade path (MK4S owners can even convert). Prusa's strengths are longevity, serviceability, documentation, and resale value — these machines stay useful and maintainable for many years. As an authorised Prusa reseller, we supply Prusa machines with full warranty and EU support. Explore the Prusa range or read our Prusa buyer's guide. Flashforge: Capability Per Euro Flashforge's pitch is straightforward: the same modern CoreXY speed, enclosures, multi-colour, and large-format capability as the premium brands — usually at a lower price. A few examples from the range: The Adventurer 5M Pro offers enclosed, filtered, 600 mm/s printing at the affordable end. The Creator 5 uses a four-toolhead FlashSwap changer that produces near-zero purge waste — a genuinely different approach to multi-colour than AMS-style single-nozzle systems. The Guider 3 Ultra delivers a 330×330×600 mm industrial build volume that the others in this comparison simply don't offer at the desktop level. The trade-off is that Flashforge's ecosystem and community are smaller than Bambu's, and it isn't open-source like Prusa. But on raw capability for the money — especially for enclosures, large format, and zero-waste multi-colour — Flashforge is consistently the value leader. As an authorised Flashforge distributor, we supply the full range with warranty and EU support.

One of the things that sets Prusa apart is choice: most machines come as either a self-assembly kit or fully assembled, and almost every part is upgradeable. That means a Prusa can be both the most affordable way in and a platform you grow over years rather than replace. Here's how the kit-versus-assembled decision works, and how Prusa's upgrade path lets you start small and scale. Kit vs Assembled: What's the Difference? The important thing to understand: a Prusa kit is the same machine as the assembled version — you simply build it yourself. It's not a stripped-down or lesser model. The parts, the performance, and the final result are identical; you trade a few hours of your time for a lower price and a deep understanding of your printer. Assembled: arrives ready to print in about 20 minutes. Best if you want to get straight to work, or you'd rather not spend a weekend building. Kit: typically 8–12 hours of assembly over one or two sessions. No soldering, all tools included, and Prusa's manuals are widely regarded as the best in the industry. You save money and you'll understand every part — which makes maintenance and upgrades far easier later. Semi-assembled (MINI+): a middle ground — the trickiest parts are done, you complete the rest quickly. A good rule of thumb: if you value your time over the saving, or you need the printer working today, buy assembled. If you enjoy building things, want to save, and plan to own the machine for years, the kit is genuinely rewarding — think of it as technical LEGO with an excellent manual. The Prusa Upgrade Philosophy Prusa's open, modular design means you're rarely stuck with what you bought. Rather than replacing a whole machine to gain a capability, you can often add it. This is a core reason a Prusa holds its value and its usefulness over time — and a key difference from sealed, hard-to-modify printers. Common upgrade paths Multi-material: add the MMU3 to an MK4S to print up to five colours or materials from a single nozzle. Enclosure for the MK4S: add the official enclosure to print ABS and ASA more reliably on an open-frame machine. MK4S to Core One+ conversion: Prusa even offers a conversion kit that transforms an MK4S into a fully enclosed Core One+, reusing many shared parts — a genuinely unusual upgrade in this industry, and a sign of how seriously Prusa takes backwards compatibility. High-temperature hotend: the HT Hotend Upgrade raises the Core One and Core One L's maximum nozzle temperature from 290 °C to 400 °C, opening the door to higher-temperature engineering materials. XL toolheads: the XL's defining feature is expandability — add toolheads (such as the Silicone Printing Toolhead) as your multi-material needs grow, up to five in total. Buy Once, Grow Over Time The practical upshot: you can start with an affordable machine and a kit build, then add multi-material, an enclosure, a hotter hotend, or extra toolheads as your work demands — without throwing the printer away. For schools, workshops, and businesses, that upgradeability is also a budgeting advantage: capability can be added incrementally rather than as a single large purchase.

Most desktop 3D printers top out around 290–300 °C at the nozzle and have little or no chamber heating. That's fine for PLA, PETG, even ABS — but it locks out the high-performance engineering polymers that aerospace, medical, and industrial work depends on. The Prusa Pro HT90 is built specifically to break that ceiling, and it does so at a fraction of the price of traditional industrial high-temp machines. Here's what it is and who it's for. What Makes It Different: Heat, and Lots of It Two numbers define the HT90. Its swappable high-temperature toolhead reaches 500 °C, and its actively heated chamber reaches 90 °C. Together, those unlock materials that warp, delaminate, or simply won't melt on a normal machine: PEEK, PEKK, PPS, PSU, PES, and PEI (Ultem) — the last of which is heavily used in aerospace for its flame resistance and strength-to-weight. The hot chamber is the critical part: high-temp polymers shrink dramatically as they cool, and only a uniformly heated chamber keeps a large part from cracking or lifting mid-print. Key Specifications Architecture Delta kinematics Build volume Ø300 × 400 mm (cylindrical) Max nozzle temp 500 °C (high-temp toolhead) Chamber Actively heated, up to 90 °C Toolheads High-temp + high-flow, both included, magnetically swappable Air handling Closed-loop HEPA recirculation Control Klipper, Input Shaper; full offline operation available Made in Prague, EU Two Toolheads: Production and Prototyping in One Machine The HT90 ships with two magnetically swappable print heads. The high-temperature head (500 °C) handles the engineering polymers above. The high-flow head performs best at 300 °C and can lay down around 1 kg of PETG or ABS in roughly 8 hours — so the same machine that produces a PEEK bracket in the morning can run fast PLA or PETG prototypes in the afternoon. Swapping takes seconds. For a workshop or lab, that means one printer covers the full development cycle rather than needing separate machines. Who It's For Engineering and manufacturing: functional end-use parts, jigs, fixtures, and chemically- or heat-resistant components in PA, PC-CF, and PPS. Aerospace and defence: PEI (Ultem) and PEKK parts, with optional fully offline operation and a removable Wi-Fi module for air-gapped, IP-sensitive environments. Medical and research: autoclavable and biocompatible high-performance polymers for implants, tooling, and lab equipment. Production bureaus: a single machine that prototypes in PLA/PETG and produces in high-temp materials. Why It Matters Commercially Industrial high-temperature printers have traditionally cost many times more than a desktop machine. The HT90 brings genuine PEEK/PEI capability to a desktop-sized, EU-made printer at a dramatically lower entry point — designed and manufactured in Prague, with the offline operation and data security that aerospace, defence, and medical buyers require. For businesses that currently outsource high-temp parts, bringing that capability in-house can pay for the machine quickly.

Once you've decided you want a larger Prusa, three machines are in play: the Core One Plus +, the Core One L, and the XL. They share Prusa's CoreXY thinking but differ sharply in build volume, chamber capability, and — in the XL's case — the ability to run multiple toolheads. Here's how to choose the right one for the size and type of work you do. Head to Head Core One Plus + Core One L XL Build volume 250×220×270 mm 300×300×330 mm 360×360×360 mm Approx. volume ~15 L ~30 L ~47 L Chamber Active, up to 55 °C Active, up to 60 °C Passive enclosure Toolheads Single Single Up to 5 independent Heatbed Standard AC convection cast aluminium Segmented (tiles) Best for All-round enclosed Large enclosed parts Multi-material / largest Core One Plus +: The All-Rounder The Core One Plus + is the baseline enclosed CoreXY — 250×220×270 mm, active chamber to 55 °C, compact footprint. For the majority of enclosed-printing needs (ABS, ASA, PC, nylon at typical part sizes), it's the right machine and the best value of the three. Choose a larger model only if you specifically need the volume. Core One L: Double the Volume, Same Footprint Philosophy The Core One L roughly doubles the build volume to 300×300×330 mm (~30 litres) while increasing the footprint by only about 10% over the Core One. It adds an AC convection cast-aluminium heatbed with very even heat distribution and an actively heated chamber up to 60 °C. This is the machine for large engineering parts printed in one piece — enclosures, jigs, fixtures, and sizeable functional components in ABS, ASA, or PC that need a reliably heated chamber across the whole build. XL: Multi-Toolhead and the Largest Volume The Original Prusa XL is a different proposition. It offers the largest build volume (360×360×360 mm) and, uniquely, up to five independent toolheads — enabling true multi-material and multi-colour printing without purge waste, since each toolhead carries its own filament and the printer swaps them automatically. Its segmented heatbed heats only the tiles in use, saving energy on smaller prints. The key distinction: the XL's enclosure is passive, not actively heated. It's superb for large multi-material prototyping and production, but for high-temperature engineering polymers that demand a hot chamber, the Core One L (or the Pro HT90) is the better tool. Which Should You Buy? Core One Plus + — most enclosed-printing needs at typical part sizes; the best value and footprint. Core One L — you need large parts in one piece with a reliably heated chamber for ABS/ASA/PC. XL — you need multi-material/multi-colour via multiple toolheads, or the largest single build volume, and a passive enclosure is sufficient for your materials. Working with high-temperature polymers like PEEK or PEI? None of these is the dedicated tool — see our Pro HT90 guide. For the whole range, see the complete Prusa buyer's guide.

The Prusa Core One and Bambu Lab's P1S and P2S are the machines most people cross-shop when they want a fully enclosed CoreXY printer in the mid range. All three are enclosed, fast, and capable of ABS and ASA. We stock both brands, so this is a straight comparison rather than a pitch — the right answer genuinely depends on what you value. Head to Head Prusa Core One Bambu P1S Bambu P2S Motion CoreXY enclosed CoreXY enclosed CoreXY enclosed Build volume 250×220×270 mm 256×256×256 mm 256×256×256 mm Chamber Active, up to 55 °C Passive Passive (Adaptive Airflow) Nozzle temp 290 °C 300 °C 300 °C Multi-colour MMU3 (single nozzle) AMS (up to 16) AMS 2 Pro (up to 16) Firmware Open source Closed Closed Made in EU (Czech Republic) China China Format Kit or assembled Assembled Assembled Where Prusa Leads: Openness, Repairability, EU Support The Core One's defining strengths are its active chamber heating (up to 55 °C, versus the passive enclosures of the P1S and P2S), its open-source firmware and ecosystem, and its EU manufacturing with genuine local support and spares. Active chamber control matters for larger ABS, ASA, and PC parts where passive enclosures can struggle as prints grow tall. The open platform means no vendor lock-in, full control over your slicer and firmware, and a repair/upgrade path that can extend the machine's life for years — Prusa's whole philosophy is a printer you maintain rather than replace. For buyers who value data privacy or want to avoid cloud dependence, this is decisive. Where Bambu Leads: Multi-Colour, Speed, Polish Bambu's strengths are a more mature multi-colour system (the AMS, up to 16 colours, is more polished than Prusa's MMU3), a slightly larger and symmetrical build volume (256×256×256 mm), a higher 300 °C nozzle, and an out-of-the-box experience that's hard to beat. The P1S is the proven, value-focused workhorse; the P2S is its modern refresh with a touchscreen, quick-swap nozzle, servo extruder, and H-series AI error detection. If multi-colour printing is central to your work, or you want the smoothest setup and the strongest app ecosystem, Bambu has the edge. The trade-offs are a closed platform and cloud-oriented workflow. The Honest Summary Choose the Prusa Core One if: you value active chamber heating for engineering materials, open-source firmware, no cloud dependence, EU support and spares, and a repairable, upgradeable machine you'll keep for years. Choose the Bambu P1S if: you want the most proven enclosed workhorse at the best price, with mature multi-colour via the AMS, and you're comfortable with a closed ecosystem. Choose the Bambu P2S if: you want that same ecosystem with the latest touchscreen, quick-swap nozzle, and smart monitoring. It often comes down to philosophy: Prusa for openness, repairability, and EU support; Bambu for multi-colour and turnkey polish. Both are excellent — there's no wrong answer, only the one that fits how you work. Available from Eolas Prints We stock both brands, shipped from Spain. The Prusa Core One comes with the advantage that we're an authorised Prusa reseller — full manufacturer warranty, genuine spares, and EU support. We also supply genuine, 100% original Bambu Lab printers. Not sure which way to go? Contact us — we'll give you a straight answer based on your materials and workflow.

If you're buying a Prusa today, the real decision usually comes down to two machines: the open-frame MK4S and the enclosed Core One Plus +. They share much of the same DNA — the same Nextruder, the same firmware ecosystem, the same Prusa reliability — but they're built around two different motion systems and two different ideas about what a printer should be. Here's how to choose. The Core Difference: Motion and Enclosure The MK4S is a bed-slinger: the bed moves on the Y axis while the toolhead handles X and Z. It's open-frame, proven over many generations, and exceptionally easy to maintain and upgrade. The Core One is a fully enclosed CoreXY: the bed only moves down in Z while a lightweight gantry moves the toolhead in X and Y, with an actively heated chamber. CoreXY plus an enclosure is what unlocks reliable ABS, ASA, PC, and nylon — and it holds quality better on tall prints. Head to Head MK4S Core One Plus + Motion system Bed-slinger (i3) CoreXY Frame Open Fully enclosed Chamber heating None (enclosure optional) Active, up to 55 °C Build volume 250×210×220 mm 250×220×270 mm Nozzle temp 290 °C 290 °C Cooling 360° high-flow 360° high-flow Speed Fast (24 mm³/s flow) ~15–20% faster than MK4S Best materials PLA, PETG, TPU (+PCCF) + ABS, ASA, PC, nylon Format Kit or assembled Kit or assembled The MK4S: Proven Open-Frame Workhorse The MK4S is the printer that built Prusa's reputation, refined across many generations. Its open design makes maintenance and upgrades genuinely easy — every part is accessible, documented, and replaceable. The custom high-flow nozzle pushes volumetric flow to around 24 mm³/s and the 360° cooling enables clean overhangs, so it's far faster than its bed-slinger layout suggests. For PLA, PETG, and TPU — the materials most people print most of the time — it's superb, and it's the more affordable entry. Add the optional enclosure later for occasional ABS/ASA, or the MMU3 for multi-material. The Core One: Enclosed, Faster, More Capable The Core One is Prusa's modern enclosed CoreXY platform. The active chamber (up to 55 °C) and sealed enclosure mean ABS, ASA, PC, and nylon print reliably without warping or layer cracking — materials that need an add-on enclosure and patience on the MK4S. It's roughly 15–20% faster than the MK4S, has 50 mm more Z-height (250×220×270 mm), and takes up less bench space than an MK4S fitted with an enclosure. It can even print PLA and PETG with the door closed, something most enclosed machines struggle with due to heat buildup. Which Should You Buy? Choose the MK4S if: you mostly print PLA, PETG, and TPU; you value the open, easy-to-maintain design and the lower price; and you don't routinely need engineering materials. It remains one of the best open-frame printers made. Choose the Core One if: you need ABS, ASA, PC, or nylon reliably; you want the faster CoreXY motion and more Z-height; or you simply want the most capable single machine and a tidy enclosed footprint. It's the better long-term platform if your material needs are growing. Still deciding between open and enclosed across the whole range?

Prusa Research has built its reputation on reliable, open-source, endlessly upgradeable 3D printers designed and manufactured in the EU. The current range spans six very different machines — from the compact MINI+ to the five-toolhead XL and the engineer-focused Pro HT90 — and choosing well means matching the machine to the materials and scale you actually work with. This guide maps the entire range so you can buy once and buy right. The First Decision: Open-Frame, Enclosed, or Professional? As with any printer range, the structure determines what you can print: Open-frame (MINI+, MK4S): No enclosure. Excellent for PLA, PETG, and TPU. The MK4S can handle some advanced materials, but ABS and ASA print best with an enclosure. Enclosed CoreXY (Core One Plus +, Core One L): Fully enclosed with active chamber heating, so ABS, ASA, PC, and nylon print reliably. Faster CoreXY motion and consistent quality at height. Large-format multi-toolhead (XL): A CoreXY platform with up to five independent toolheads for true multi-material printing at large scale. Professional high-temperature (Pro HT90): A 90 °C actively heated chamber and 500 °C toolhead for engineering and aerospace-grade polymers like PEEK and PEI. The Full Range at a Glance Printer Type Build volume Chamber Best for MINI+ Open frame 180×180×180 mm None (enclosure optional) Compact, affordable entry; PLA/PETG MK4S Open frame 250×210×220 mm None (enclosure optional) Flagship workhorse, fast, upgradeable Core One Plus + Enclosed CoreXY 250×220×270 mm Active, up to 55 °C All-round enclosed; ABS/ASA/PC Core One L Enclosed CoreXY 300×300×330 mm Active, up to 60 °C Large enclosed engineering parts XL Large-format CoreXY 360×360×360 mm Passive enclosure Multi-toolhead, large multi-material Pro HT90 Delta, high-temp Ø300×400 mm Active, up to 90 °C PEEK, PEI, professional polymers The Open-Frame Tier: MINI+ and MK4S The Original Prusa MINI+ is the most affordable way into the Prusa ecosystem. With a 180×180×180 mm build volume, a 280 °C nozzle, and a 100 °C bed, it is a capable little machine for PLA, PETG, and TPU — and our Enclosure Bundle adds the option to tackle more demanding materials. It is available semi-assembled, making it a popular choice for education and first-time buyers. The Original Prusa MK4S is Prusa's flagship open-frame workhorse and the backbone of countless workshops and print farms. Its 250×210×220 mm build volume, custom high-flow nozzle (raising volumetric flow to around 24 mm³/s), and 360° part cooling make it genuinely fast while keeping the open, easy-to-maintain design Prusa is known for. Add the optional enclosure for ABS and ASA, or the MMU3 for multi-material printing. Available as a kit or fully assembled. The Enclosed CoreXY Tier: Core One Plus + and Core One L The Prusa Core One Plus + is Prusa's fully enclosed CoreXY machine — the natural step up when you need ABS, ASA, PC, or nylon. Its actively heated chamber reaches up to 55 °C, the CoreXY motion delivers travel speeds up to around 600 mm/s, and it prints roughly 15–20% faster than the MK4S while taking up less space than an enclosed MK4S. Build volume is 250×220×270 mm — taller than the MK4S thanks to extra Z-height. The Prusa Core One L takes the same enclosed CoreXY concept and roughly doubles the build volume to 300×300×330 mm (~30 litres) while increasing the footprint by only about 10%. It adds an AC convection cast-aluminium heatbed with very even temperature distribution and an actively heated chamber up to 60 °C — the choice when you need large enclosed engineering parts in one piece. The Large-Format Multi-Toolhead: Original Prusa XL The Original Prusa XL is the flagship of the range — a large-format CoreXY platform with a 360×360×360 mm build volume and, uniquely, support for up to five independent toolheads. Multiple toolheads mean true multi-material and multi-colour printing without the purge waste of single-nozzle systems: each toolhead carries its own filament, and the printer parks and swaps them automatically. It is the right machine for large objects, multi-material assemblies, and production workflows. Note its enclosure is passive, not actively heated — for high-temperature engineering polymers, the Pro HT90 is the dedicated tool. The Professional High-Temp Machine: Prusa Pro HT90 The Prusa Pro HT90 is a delta-kinematics printer built for engineers. Its actively heated chamber reaches 90 °C and its swappable high-temperature toolhead reaches 500 °C — enabling small-to-mid-sized parts in PEEK, PEKK, PPS, PSU, PES, and PEI (Ultem), the aerospace-grade materials most desktop printers cannot touch. A high-flow toolhead is also included for fast PLA, PETG, and ASA, and a closed-loop HEPA recirculation system keeps the chamber air clean. The cylindrical build area is Ø300×400 mm. For production, research, and B2B engineering, this is the most affordable route into high-performance polymers.
