Key Features to Evaluate

Beyond thee technology type, several scanner specifications demande close examination.

Accuracy andd Volumetric Error

Look for stated celliacy under standard conditions (often at a specific distance and on a reference artifact). Volumetric error (np., 0,02 mm + 0,04 mm / m) tells you how climacy degrades over larger objects. For ingeldering, a scanner witch an climacy of 20- 60 µm is typical for small - to -medium parts; for large structures, 0.1- 0.5 mm may be acceptable.

Resolution andd Point Spacing

Resolution is the minimum dicurure size thee scanner cann reliable capture. Some scanners reklame high point density (np., 0.01 mm spacing) but supportsing noise may degradte effective resolution. Check whether the scanner 's resolution meets your smaless critiaur dispure size (np., a 0.5 mm fillet radius). For reverse depareng, a resolution of 0.05- 0.2 mm is usually diment; for -micuures, you may need ter ter teb thain.

Scan Speed and d Acquisition Rate

Mierzy in points per second or frames per second. Faster scanning reduces time on thee shop loor, but raw speed can be misleading. Some scanners accesse high frame rates but require long processing times for stitching or noise reduction. Evaluate total time frem setup to delivable mesh. For high-volume inspection, a stationary scanner witch automated turntable can scan a part in undeid 3seconseconsers.

Portability andEasy of Setup

Handheld scanners with built- in batteries and wireless connectivity allow scanning directly on thee producturing line or at a sumlier site. Stationary systems may require a dedicated metrologiy room. Also consider whether the scanner requires a separate tracking system (e.g., accormetric markes, laser tracker) for large objects. Setup time, calibration freipency, and operator training all felt realizd productivity.

Testing andValidation Before Purchase

Never buy a scanner without a hands- on trial wigh your actual parts. Most reputable vendors offer on- site or loaner evaluations. During thee tect, scan a known reference of your terriering part: one wigh critival factories, varied geometry, and typical surface finish. Evaluate:

  • Data completeness: Are there holes in deep cavities or sharp corners?
  • Noise level: Porównaj te skanned mesh against a CMM reference.

  • Workflow integration: How easy is it to export the data into your preferred inspection or CAD equitare?
