What are the key factors that determine the precision of a 3D printer?

Precision hinges on several pillars:

Hardware design: The quality of motors, rails, and optical systems (especially in resin printers) directly impacts how finely the printer can position its print head or laser.
Material properties: Shrinkage, viscosity, and curing behavior of filaments or resins affect dimensional stability.
Calibration and maintenance: Regular calibration ensures the printer’s axes move accurately; neglecting this leads to drift and inaccuracies.
Slicing and print settings: Layer height, print speed, and support structures influence the final detail and dimensional fidelity.
Environmental factors: Temperature and humidity can cause warping or inconsistent curing.

How does the type of 3D printing technology impact the accuracy of the printed object?

Different technologies have inherent strengths and weaknesses:

FDM: Uses melted filament extruded through a nozzle; precision is limited by nozzle diameter and filament flow control. Layer lines are visible, and parts can be anisotropic.
SLA/DLP/MSLA: Use light to cure resin with high resolution; capable of very fine details and smooth surfaces. Accuracy depends on laser spot size or pixel size and resin properties.
SLS/MJF: Fuse powder particles with lasers or heat; excellent for complex geometries and functional parts with good isotropy, but surface finish is slightly rougher.
Material Jetting: Deposits droplets of photopolymer cured by UV light; offers ultra-high precision and multi-material capabilities but at a premium price.

What are the most precise 3D printing technologies available in the market today?

The resin-based vat photopolymerization methods (SLA, DLP, MSLA) currently lead the pack in precision, with layer thicknesses as low as 25 microns and XY resolutions down to 25 microns or better. Material Jetting also offers exceptional detail but is less common for hobbyists.

Industrial powder bed fusion methods like SLS and MJF provide excellent accuracy for functional parts but with slightly coarser surface finishes.

Which 3D printer brands are known for producing high-precision prints and have won awards for their quality?

Formlabs: Renowned for their Form series SLA printers, combining precision, reliability, and a broad material palette. Their Form 4 and Form 4L models have won multiple industry awards.
Prusa Research: Their i3 MK3S+ FDM printer is praised for precision within its category and excellent reliability.
Anycubic: Offers affordable MSLA printers like the Photon Mono X, delivering impressive precision for the price.
EOS: A leader in industrial SLS printers, providing high precision for demanding applications.
