<div>Can We Build a 1-Metre High-Temperature Toolchanger 3D Printer?
</div>
<div><br />
</div>
<div>I’m building a custom large-format 3D printer with a planned build volume of roughly 1020 × 510 × 800 mm, a heated chamber, multiple interchangeable toolheads and potentially closed-loop linear motor motion.
</div>
<div><br />
</div>
<div>The reason is simple: there is a huge gap between affordable consumer 3D printers and genuinely capable large-format machines.
</div>
<div><br />
</div>
<div>Consumer machines are getting faster and smarter, but once you want a large build volume, high-temperature materials, multiple independent tools and a properly heated chamber, prices rise dramatically. For demanding hobbyists, makers and small businesses, there are surprisingly few affordable options.
</div>
<div><br />
</div>
<div>I want to see if that gap can be closed.
</div>
<div><br />
</div>
<div>A large part of the donor hardware is already here: aluminium profiles, build plates, heaters, motors, electronics and mechanical parts. The machine is therefore not starting as an idea on paper — the physical build is already being prepared.
</div>
<div><br />
</div>
<div>The current goals are:
</div>
<div><br />
</div>
<div>* around 1020 × 510 × 800 mm build volume
</div>
<div>* approximately 90 °C heated chamber
</div>
<div>* up to 120 °C bed temperature
</div>
<div>* initially 2 interchangeable toolheads
</div>
<div>* expandable to more tools later
</div>
<div>* support for ABS, ASA, Nylon and other engineering materials
</div>
<div>* minimal purge waste
</div>
<div>* Klipper-based control
</div>
<div>* a modular, repairable and upgradeable design
</div>
<div><br />
</div>
<div>The fundraising target is €5,000.
</div>
<div><br />
</div>
<div>That budget would allow me to go beyond a basic belt-driven prototype and seriously investigate technologies such as closed-loop ironless linear motors, dual-gantry motion, high-temperature toolheads and professional motion components.
</div>
<div><br />
</div>
<div>Most importantly, this project is intended to become more than a one-off printer.
</div>
<div><br />
</div>
<div>If the concept proves successful, my goal is to develop this further into a core part of my business: offering custom large-format and high-performance 3D-printing solutions for demanding consumers and small professional users who need more than standard consumer printers can provide, without immediately moving into industrial-machine pricing.
</div>
<div><br />
</div>
<div>The entire development will be documented openly through a build blog: component choices, costs, prototypes, mistakes, testing and eventually the completed machine.
</div>
<div><br />
</div>
<div>So the goal is not simply to fund one expensive printer.
</div>
<div><br />
</div>
<div>It is to build and prove a concept that could lead to a new class of affordable, configurable machines for people who currently have very few realistic options.
</div>
<div><br />
</div>
<div>Any contribution helps move the project from collected hardware to a working machine.
</div>
<div><br />
</div>
<div>And if you cannot contribute financially, sharing the project with the 3D-printing, Klipper, Voron, VZBot, RepRap or maker communities is just as valuable.
</div>
<div><br />
</div>
<div>Ja. Voor GoFundMe zou ik hem vooral transparant en geloofwaardig maken, zonder te doen alsof ieder onderdeel al definitief gekozen is.
</div>
<div><br />
</div>
<div>How the money will be used
</div>
<div><br />
</div>
<div>The project already has a substantial amount of donor hardware available, including aluminium profiles, build plates, heaters, PEI sheets, motors, electronics and a Creality K2 Plus for producing prototype parts. The €5,000 target is therefore intended mainly for the components that cannot realistically be sourced from the existing inventory.

</div>
<div>Category	Estimated budget
</div>
<div>XY motion system — linear rails, motors/drives, encoders, gantry hardware	€1,500
</div>
<div>Toolchanger + first two complete toolheads	€850
</div>
<div>Main electronics, power supplies, CAN, switching and safety hardware	€650
</div>
<div>Heated enclosure, chamber heater, door/panels, seals and insulation	€650
</div>
<div>Z system, bed carrier and additional mechanical hardware	€450
</div>
<div>Wiring, connectors, sensors, fans and thermal monitoring	€300
</div>
<div>Shipping, import costs and transaction fees	€300
</div>
<div>Prototyping, failed parts and design revisions	€300
</div>
<div>Total	€5,000
</div>
<div><br />
</div>
<div>These are target allocations rather than fixed purchase orders. The final component choice will depend on supplier quotations, temperature ratings and what proves technically suitable during development.
</div>
<div><br />
</div>
<div>If a component can be sourced for less, the difference will remain within the project budget and be used for another part of the machine rather than increasing unnecessary specification.
</div>
<div><br />
</div>
<div>The most expensive single decision is likely to be the XY motion system. I am currently comparing conventional belt-driven motion with closed-loop linear motor systems. If a suitable linear motor solution can be obtained within budget, that would substantially increase the capability of the machine.
</div>
<div><br />
</div>
<div>Existing hardware and my own labour are not included in the €5,000 target.
