3D Printhead Kinematics
In the production of various functional products such as machine parts and structural elements, quality assurance issues are of particular importance.
So, due to the layer-by-layer formation of a printed product, stripes form on its surface. The stepped look is best seen on curved and curved surfaces. It becomes more pronounced as the layer thickness increases. Stepping may not affect the strength of the printed product in any way, it most often only increases its roughness. However, if the product does not require a low level of roughness per se, but only the appearance (for example, if we are talking about instrument cases), you can resort to a simple finish of the outer surfaces. Significant dimensional errors and distortion of the shape of products that can be tolerated during printing are a much bigger problem. In the most common 3D printers using layer-by-layer fusing technology (FFF, Fused Filament Fabrication), two main factors are of decisive importance: temperature shrinkage of the material and positioning error.
The shrinkage of the printed object is determined by the physics of the process: the molten material is squeezed onto the platform layer by layer and solidifies in the form of the final product, and in the process of cooling from the melting temperature to room temperature, it seems to shrink.
Different materials can shrink more or less, but this process is always uncontrollable. In some cases, it can be assumed that shrinkage occurs uniformly in all directions by a certain percentage. Based on this assumption, corrections can be made to the control program (G-code) that can partially compensate for the shrinkage error.
An equally important role in ensuring accuracy is played by the positioning accuracy of the working body of the equipment, i.e. the print head of the printer.
To date, many options have been proposed for building a system for moving the print heads of 3D printers, however, systems based on belt drives are most widely used. This is due to the fact that the load acting on the print head during operation is relatively small (unlike metal-cutting machines, printers do not have such a powerful disturbing factor as cutting forces), so such kinematic schemes provide sufficient rigidity. At the same time, they are characterized by simplicity, economy and high speed of movement, which positively affects productivity.
However, at the moment, the factors affecting the accuracy of the positioning of the print head in such systems remain poorly understood. There are no practical recommendations on choosing the configuration of the kinematic scheme and the dependence of positioning errors on the operating parameters (mass of the print head, dimensions of the construction area, belt pretensioning, gaps in movable joints, etc.) of the 3D printer.
Among the known variations of kinematic systems based on belt drives, one of the most common is the H‑Bot single circuit. It has a single belt in the form of the letter “H” and is driven by two motors ( fig. 1 ). A small number of moving elements in this circuit reduces the inertia, which positively affects the positioning accuracy. It also increases due to the fact that when the motors are rotated by 1 step, the print head travels a linear distance equal to half a step. However, in this system, the unidirectional rotation of the motors required to move the printhead along the X-axis results in multidirectional forces that cause the transverse rail to skew relative to the longitudinal ones.
The non-perpendicularity of the guides leads to the appearance of a gross error in the shape of the final product - for example, an object with a rectangular section will take the form of a parallelogram. In addition, the fastenings of the transverse guide to the longitudinal ones suffer from a repeated cycle of rectification skew, and the system resource is reduced.
Fig. 1. H‑Bot kinematic movement system
In it, the use of two drive belts balances the impact on the moving elements, thereby maintaining their correct geometric arrangement. The system uses more bypass rollers than the H‑Bot system (2 more). However, in this scheme, it becomes necessary to ensure equal pre-tensioning of both circuits. In the event that one belt is tightened more than the other, with unidirectional rotation of the motors, as in the H-Bot scheme, a pair of forces appears applied to the transverse guide. The resulting moment of forces rotates the movable unit in the XY plane, this causes a violation of the perpendicularity of the guides and also leads to positioning errors and accumulative deformation of the elements of the movement system.
To avoid cases of belt intersections, their contours are located in different planes - this leads to additional bending moments on the print head carriage.
Fig. 2. CoreXY motion system
Compared to H‑Bot, the dual circuit motion system has less dynamic error caused by stretching of the belts during acceleration and deceleration of the print head: the presence of two parallel belt branches doubles the rigidity of this oscillatory system.
0027 fig. 3 ). This moving device has two belt circuits. The primary circuit belt is fixed on both sides of the carriage with a single guide roller and performs the function of moving the head along the X axis. 3. Kinematic movement system Markforged
The same circuit is driven when moving along the Y axis, but in this case the second circuit belt is also driven, fixed on the movable unit. Despite its simplicity, the scheme combines the disadvantages of both previous schemes - it requires equal belt tension and, at the same time, regardless of the tension, it tends to rotate the movable unit during unidirectional rotation of the motors.
This scheme is not widely used among manufacturers of additive plants.
Another kinematic system in which each motor is responsible for moving along its own axis is the Ultimaker system. In it, the print head is driven by a transverse guide, which is fixed in the transverse blocks and slides along the central longitudinal guide, fixed in the longitudinal blocks. This kinematic scheme has high structural rigidity and low inertia of the print head. The system also includes closed loop belts, which in theory should provide equal belt tension. These characteristics have a positive effect on positioning accuracy. Nevertheless, the scheme is sensitive to the initial mutual setting of the guides, the error of their relative position is reflected in the shape of the printed products, similar to the skew of the movable unit in previous systems. The disadvantages of the Ultimaker circuit include a complex implementation and high quality requirements for linear motion components.
Fig. 4. Ultimaker Kinematic Handling System
There are other belt driven motion systems that have become less common due to significantly greater complexity or more disadvantages.
In the production of its own 3D and 5D printers (Stereotech 320 and Stereotech 520 ( fig. 5, 6 ) Stereotech uses its own patented STE HeadMotion print head movement system ( fig. 6, 7).
Fig. 5. Stereotech 3D printers: Stereotech 520, Stereotech 320
Fig. 6. General view of the Stereotech 320 3D printer in a housing without a top cover with a kinematic system STE HeadMotion
The print head movement system includes one transverse and two longitudinal rail guides. The longitudinal guides are rigidly fixed on the base in the direction of the Y axis, the transverse guide is located along the X axis and is connected to the longitudinal ones through the carriages.
The print head moves with two drive belts, as in the CoreXY scheme, to increase the rigidity of the drive system and reduce the inertial error. The ends of the belts are fixed to form two connected contours on the print head carriage. The symmetrical arrangement of the contours compensates for bending moments on the bearings and guides of the moving parts of the system.
To solve the problem of ensuring equal belt tension in the circuits, a tension equalization unit is included in the device. It is a lever with two rollers at the ends (each of which is part of a separate circuit), hinged on the base with the ability to rotate in the XY plane, and works on the principle of a swing. When a difference in tension forces appears in the circuits, the lever turns, the rollers move, and both circuits return to equilibrium. To dampen vibrations, dampers are installed at the ends of the lever ( fig. 7, 8 ).

8. Calculation diagram of the tension force equalization unit
The movable unit with a transverse guide is made in the form of a single portal to increase the rigidity of the device, which also has a positive effect on positioning accuracy.
The motors are mounted on the base of the printer to reduce the mass of moving parts and reduce inertial moment. Their unidirectional or multidirectional movement causes the print head to move along the X or Y axis, respectively; turning each motor individually moves the head diagonally.
The frame base of the moving device can be made of connected profiles, plates and other elements that are arranged in parallel and connected transversely to each other.
