spools to your order, so you can try different things!
Hobbies, Household & Fun
Creative Projects
PLA is the ultimate "first print" filament. It is easy to use, comes in every color, and is perfect for
detailed toys, board game pieces, desk gadgets or kitchen accessories.
Repairs & Workshop Projects
Replacement Parts
Fix broken appliances with PETG or PCCF. Print RC cars, drones, and mechanical parts.These materials
are tough, heat-resistant, and create parts that often outlast the original.
Gadgets & Protection
Impact Absorbers
TPU is a rubber-like material ideal for custom phone cases, GoPro mounts, seals, and protective bumpers.
The possibilities are nearly endless!
Engineering & Safety
The WOW! factor
You can get all sorts of materials for your CORE One+, including the brightest glow-in-the-dark
filament on the market or beautiful Woodfil filaments.
The fastest way from idea to 3D print
Introducing EasyPrint!
People often ask: how difficult it is to begin with 3D printing? With EasyPrint, anyone can start in a
few minutes. Prusa EasyPrint app runs in any browser - on your phone, tablet, or laptop. Browse
a model on Printables.com, open it in EasyPrint, and send it straight to your CORE One+.
Print Sheet Replacement (lasts hundreds of print hours)
Print sheets are double-sided - if one side is worn, swap to the other side ~ $ 37
Software & updates
PrusaSlicer, EasyPrint, Prusa Connect, Prusa App, and updates - included and free. $0
Most users spend $25–50/month on filament. Everything else (PrusaSlicer, Prusa Connect,
firmware updates) is free. A CORE One+ bought today will still be printing strong years from now.
One spool = over 80 different objects!
You can print A LOT with a single spool of filament.
One kilogram of filament prints one kilogram of objects - but that's a bit difficult to imagine. Check out
the photo below to see how many things we printed with a single spool of Prusament - it's over 80 different objects!
Accessories to consider
CORE One+ works perfectly out of the box. Still, you may want to consider these accessories to
level up your 3D printing game.
1080p Camera with Night Vision Function
Install an optional 1080p camera for remote print monitoring. The camera connects using a
USB-C cable directly into the motherboard and requires an active Wi-Fi connection to function.
Advanced Filtration System
The optional Advanced Filtration System is useful when you print materials such as ASA and other
materials that produce an increased number of ultra-fine particles and fumes during printing.
Additional nozzles, print sheets and filaments
Depending on what you want to print, you might consider adding a hardened nozzle (for abrasive
engineering materials) or smaller nozzles for printing detailed models.
Six engineering choices that set the CORE One+ apart.
CoreXY uses two fixed motors in the corners that pull on a long, continuous loop of belts to move a
tool head. Because the heavy motors are fixed in place, the gantry is incredibly light, allowing for blazing
fast speeds and outstanding precision.
Fully Enclosed CoreXY Architecture
The advanced CoreXY motion system moves the lightweight printing head instead of the heavy base,
allowing for much higher speeds without losing quality. Input Shaper firmware compensates vibration
at high speeds, with travel speeds reaching 600 mm/s.
Active Chamber with Smart Ventilation
The printer's enclosed chamber heats up to 55 °C. The system monitors temperatures at all times
and adjusts automatically to create the best environment for any material you choose. Optional
HEPA filtration integrates directly into the enclosure for offices and schools.
Nextruder: Precision at Every Layer
Nextruder is our next-gen print head featuring a precise Load Cell sensor that measures force at the
nozzle tip - the nozzle itself becomes the probe. Because it is physical, it cannot be confused like optical
sensors. Plus, 360-degree cooling means steep overhangs print cleanly without supports and nozzles
(0.25 mm to 0.8 mm) are swappable in seconds without tools.
Robust Steel Exoskeleton
All-steel exoskeleton - the enclosure is structural, not an accessory. Exceptional rigidity at high speeds.
Nothing is glued. Everything comes apart with a screwdriver. Designed for modders and tinkerers -
replacement parts stocked for years.
Compact Footprint, Large Volume
50% less desk space than an MK4S inside an enclosure, yet 30% more print volume (250 × 220 × 270 mm).
That efficiency matters whether you're fitting one printer on a desk or 600 into a print farm - which is exactly
what Prusa Research does at their own facility.
Open‑Source Hardware & Firmware
CAD files are published. Firmware source code is on GitHub. You can inspect, modify, or compile
your own version. No locked bootloaders, no cloud dependency. We've been shipping open-source
printers since 2012.
The key to successful prints
Active Chamber Temperature Control
Engineering materials warp when they cool unevenly - corners lift, layers separate, prints fail.
CORE One+ prevents this with a compact chamber that hits up to 55 °C, creating a stable
environment. And the best thing? While other printers need you to open the door for printing
low-temp materials (like PLA), you can keep the CORE One+ door closed thanks to smart
chamber ventilation.
Prusa CORE One+ Assembly kitThe best way to get to know your 3D printer
With Prusa printers, you get the unique opportunity and enjoy one of the most exciting projects
imaginable - building your own CORE One+! We have a long history of offering 3D printer kits
and we perfected the process over the years. You'll get a complete package with a detailed
guide (think LEGO Technic) and in the end, you will have exactly the same machine as in the
pre-assembled package, but with the added bonus of knowing it inside out.
Your Printer, Your Rules
Experience a printing platform designed with transparency, repairability, and your creative freedom in mind.
You own your 3D printer, not just a license to use it
Any Filament, Any Brand
CORE One+ works with any standard 1.75 mm filament. Use Prusament for tested quality or pick your
favorite brand. PrusaSlicer includes over 200 ready-made profiles, and you can always create your own
for new materials.
Connection is Optional
Print via USB drive or your local network - no internet connection required. Optional Prusa Connect
adds remote monitoring and print farm management. You don't have to connect the printer to the internet;
not even once.
Open‑Source Files
The firmware source code is on GitHub and CAD files are published at Printables.com. You can
inspect, modify, or build your own version. Tinkering is optional, but if you want to mod your printer,
you have all the resources.
Free Software, No Tiers
PrusaSlicer, EasyPrint, Prusa Connect, the Prusa App, and every firmware update - included
with the printer and free. No forced ads, no hidden subscription tiers.
Right to Repair
Nothing is glued. Everything comes apart with a screwdriver. We keep spare parts in stock
for years after release. A worn nozzle (after hundreds of print hours) is a $20 swap, not a reason
o worry.
Upgradability
Whenever it's even remotely possible, we offer our customers a clear and transparent upgrade
path. When an improved model comes out, you can usually upgrade the printer you have at home.
100% Privacy: Offline Mode without Compromise
You don’t have to connect the CORE One+ to the network - not even once, and you can still enjoy the
full experience without any drawbacks. The printer can be configured and operated offline, including
slicing and installation of firmware updates. The Wi-Fi module can be easily unplugged for environments
with the highest level of security.
We believe that no matter whether you’re developing a new-generation space shuttle, or just printing
toys for your kids, no organization should be interested in gathering information about your prints or
your printer’s surroundings

Making 3D printers since 2012
From the heart of Europe to the entire world
Prusa Research is a 3D printer manufacturer based in Central Europe - in Prague, Czech Republic.
It is now a team of over 1,000 people with a brand new factory opened in Delaware, USA. But it s
tarted as a one-man project.
In 2010, Josef Průša designed an open-source printer that hobbyists could actually afford. It caught
on. Years later, the company is still in Prague, still independently owned, and still making printers the
same way - designed in-house, built to last, and shared openly with the community that helped build
them. A lot has changed in 3D printing. Not everything needs to.
