Print-in-place 3D printing is one of the most remarkable innovations in consumer additive manufacturing. The concept is straightforward but the engineering is sophisticated: a complete mechanism with working joints, hinges, or flexible segments is printed as a single object in one continuous print job. Nothing is assembled afterward. The finished piece comes off the build plate ready to move, flex, and pose.
At 3DCentral, print-in-place designs are among our most popular products. Our articulated figurines collection features hundreds of print-in-place designs from top community artists and our own original catalogue, all produced at our facility in Laval, Quebec. This guide explains how print-in-place works and highlights the best designs available in 2026.
How Print-in-Place Technology Works
Every print-in-place design relies on a single core principle: precisely calibrated clearance gaps between moving parts. When a designer creates an articulated joint, they model the ball and socket (or hinge and pin) with a gap between them, typically 0.2 to 0.4 millimetres. During printing, the printer deposits material on both sides of this gap. The gap is narrow enough that the parts are captured within each other, but wide enough that they never fuse together.
The Role of Tolerances
Tolerance engineering is what separates a good print-in-place design from a failed one. Too tight and the joints fuse solid. Too loose and the mechanism falls apart. The best designers, like Flexi Factory and Cinderwing3D, have refined their tolerance specifications through extensive testing across different printer brands and configurations.
Why Industrial Printers Matter
Print-in-place designs are more demanding than static prints because they require consistent dimensional accuracy throughout the entire build. At 3DCentral, our fleet of over 200 industrial printers maintains the tight calibration standards necessary to produce reliable print-in-place results at scale. This consistency is why our articulated figurines arrive with smooth, properly functioning joints every time.
Best Print-in-Place Dragons
Dragons are the flagship category for print-in-place design. The long, segmented dragon body is perfectly suited to articulated printing, with each vertebra-like segment serving as an independent joint.
Top Picks
Cinderwing3D crystal dragons combine translucent filament with fine scale detail and dozens of articulating segments. Flexi Factory dragons optimise for joint smoothness and satisfying tactile movement. Community artists bring their own interpretations, from cartoon-style baby dragons to imposing elder dragons.

Best Print-in-Place Animals
Nearly every popular animal has been reimagined as a print-in-place design. The engineering challenge varies by species: a snake is relatively simple (linear chain of segments), while an octopus with eight independently flexible tentacles is significantly more complex.
Top Animal Picks
Articulated foxes with poseable tails, waddling penguins, hugging teddy bears, and flexing ducks are all available as print-in-place designs. Octopuses with eight curling tentacles are engineering showcases that demonstrate the full potential of the technique. Caterpillars and worms with wave-like flexibility offer a different kind of tactile satisfaction.
Best Print-in-Place Mechanisms
Beyond figurines, print-in-place technology powers a range of mechanical designs: working gears, planetary gear sets, hinged boxes, folding structures, and kinetic sculptures. These pieces appeal to engineering enthusiasts and make excellent conversation pieces.
Functional Mechanisms
Print-in-place fidget cubes, gear spinners, and chain links demonstrate the technology in a compact, tactile form. These designs are satisfying to manipulate and serve as impressive demonstrations of what additive manufacturing can achieve in a single print operation.
Material Impact on Print-in-Place Performance
PLA: The Standard Choice
PLA is the default material for print-in-place designs. Its relatively low shrinkage rate and excellent dimensional accuracy make it ideal for maintaining the precise tolerances that articulated joints require. The vast majority of our print-in-place catalogue is produced in PLA.
PETG: For Durability
PETG’s slight flexibility and superior fatigue resistance make it excellent for print-in-place joints that will be manipulated frequently. The joints flex more smoothly and resist micro-cracking better than PLA under repeated stress. However, PETG requires tighter printing calibration due to its different shrinkage characteristics. See our PLA vs PETG guide for details.
Silk PLA: Premium Aesthetics
Silk PLA adds a metallic lustre to print-in-place designs without significantly affecting joint performance. Gold, silver, and copper silk filaments produce stunning articulated pieces that look premium under any lighting condition.
Caring for Print-in-Place Designs
Print-in-place figurines require the same basic care as static collectibles, with a few additional considerations for the mechanical joints.
Joint Maintenance
If a joint feels stiff after initial printing, gentle working of the joint back and forth will loosen it without damaging the mechanism. This is normal for new print-in-place pieces and typically resolves within a minute of gentle manipulation. Avoid forcing any joint beyond its designed range of motion.
Dust and Debris
Fine dust can accumulate in joint gaps over time, potentially causing stiffness. Compressed air directed into joint areas removes debris effectively. For comprehensive care guidance, see our figurine care guide.
Featured Print-in-Place Artists
Flexi Factory is widely regarded as the pioneer of consumer print-in-place design, with a catalogue spanning dozens of animal and character designs. Cinderwing3D has elevated dragon articulation to an art form. TwistyPrints innovates with unusual joint mechanisms. McGybeer and Zou3D each bring distinct artistic styles to the print-in-place format.
3DCentral’s catalogue combines these community artists with our own original designs, offering collectors and gift buyers the widest possible selection from a single trusted source.
For Print Farm Operators
Print-in-place designs are premium products that justify higher prices due to their interactive nature and engineering complexity. Quality control is especially important: every joint must be tested before shipping. The 3DCentral Commercial License provides commercial production rights for original 3DCentral print-in-place designs. The licence covers 3DCentral originals only; for community artist designs, contact the artist directly. See our print farm guide for more.

Frequently Asked Questions
What does print-in-place mean?
Print-in-place means the entire object, including all moving parts and joints, is manufactured in a single continuous 3D print with no assembly required afterward.
Do print-in-place designs require any assembly?
No. The finished piece comes off the printer with working joints. No glue, screws, or tools are needed.
Are print-in-place joints strong?
Yes. Properly designed and printed joints are durable under normal handling. PLA joints last indefinitely with occasional posing. PETG joints offer better fatigue resistance for daily heavy use.
Can I print these designs on my own printer?
Print-in-place designs require well-calibrated printers with consistent dimensional accuracy. If you own a 3D printer and want to produce these designs commercially, the 3DCentral Commercial License provides access to original 3DCentral designs.
