Configuring a 3D printer yourself: build volume, extruder and options

A walk through our configurator: which model is built for what, why the build volume is rounded and what lies behind each option.

Our configurator lets you put together an industrial printer to your own dimensions – model, build volume, equipment, guide price. This article works through what lies behind each point and why we solved some things the way we did.

The question wizard – or straight to a model

If you do not yet know which system fits, you answer three questions: what would you like to process, which material, and should the material blend change during the process? From that the wizard suggests a model. If you already know what you need, simply skip it.

Why “system printer” is meant literally

On the UniversalPrint, KeraPrint and MultiPrint the frame is identical. We swap the size and individual components – nothing more.

  • KeraPrint: for highly filled plastics, ceramics and compounds, with fully hardened components in the extruder.
  • UniversalPrint: the same platform without the hardening, because it is not needed with ordinary plastics.
  • MultiPrint: for several heads, up to five or six, and for blending pellets within the process – with regrind, colour powders and other additives.

The CorePrint is the exception: it uses CoreXY kinematics, where the head genuinely moves in X and Y. That brings advantages in speed and makes sense above all if you work primarily with filament and only occasionally use pellets.

Why our pellet extruder stays put

On the other models the heavy pellet extruder hangs statically on the gantry and the print bed moves. That is a deliberate decision: it keeps extrusion continuous. We would rather build everything around it more substantially in order to print precisely regardless.

Entering the build volume – and why it is rounded

You enter width, depth and height. These are rounded, and there is a practical reason: mechanically it makes no difference to us whether shafts and linear guides are graduated to the millimetre. If you need 340 mm we build 350 mm and limit the 10 mm in software. In price terms that hardly matters.

Price grows with size – in our production as much as in your purchase.

Mechanics and the question of accuracy

The print bed systems are substantially built: 20 mm linear guides and 16 mm ball screws in X, Y and Z.

We state an accuracy of 0.1 mm. As a rule we comfortably better that – usually we are around five hundredths of a millimetre. Even so, we state 0.1 mm. What you claim and what you achieve are always two different things: if you run too fast there can be a slight jolt. We would rather be honest about that.

Tabletop or base cabinet?

On the KeraPrint, below a certain size there is the tabletop version without a base frame. Whether that makes sense depends on your space. With many heads or pneumatic conveying the base cabinet pays off, because components can be stowed inside – which reduces the overall footprint again.

If you notice different display sizes in the photo gallery: we keep developing. The tabletop shows the latest version; the large display will be retrofitted to the other models step by step.

The options in detail

  • Closed enclosure: sensible with ABS. With many ceramics and compounds, however, printing temperatures are low and we need cooling – then the enclosure is an option, not an obligation. Chamber filtration goes with it.
  • On-board slicer: with the new display it becomes possible to slice a STEP file at the machine and start it there. The detour via a computer and a USB stick disappears – in laboratories and large buildings that saves noticeable working time.
  • Custom lettering: your company logo on the housing.
  • Service and maintenance: our machines are built so that wear parts can also be bought from other manufacturers – ball screws are no mystery. That matters to us. If you would rather not deal with it, book the package: we come by once a year, service and update.
  • IT security package: where data security is a priority. Usually it comes down to a local USB port or coordination with your closed company network.
  • Pneumatic conveying: instead of refilling the hopper, you draw from a 5 kg container or a 20 kg bucket. Sensors top it up only when the machine consumes material. On the MultiPrint the number depends on the heads.

An outlook

The multi-head setup you see in the photos today will not stay that way. We are moving towards a revolver head that brings several heads to the same position. Together with pneumatic conveying, materials can be blended in – colour gradients, strength gradients, one head printing fine and another dense.

Because the gantry is substantial, you can also fit other heads. An additional filament extruder in 1.75 or 2.85 mm connects plug and play thanks to our boards: the printer recognises for itself which head is fitted.

It ends in a conversation

You submit the configuration with your name and company, and we come back with a quotation. What comes out of it we match to your actual requirement – mechanics, software and, in future, the AI monitoring the process, we see as one system.
