3D Printer Filament Inspection Systems
Taymer designs and manufactures inline quality inspection systems for 3D printer filament extrusion lines. Founded in 1961, Taymer has installed 4989 systems in 55 countries and is ISO 9001:2015 certified. Our surface and dimensional inspection systems detect diameter variation, lumps, neckdowns, and surface defects in real time during filament extrusion — before defective filament reaches a spool.
Why Filament Manufacturers Need Inline Inspection
Defective filament — inconsistent diameter, surface flaws, lumps, or neckdowns — causes failed prints, nozzle clogs, and damage to the printer itself. For filament manufacturers, that translates into returns, warranty disputes, and lost customers. Taymer’s inline inspection systems measure and inspect filament continuously as it’s extruded, flagging out-of-tolerance material before it’s wound onto a spool.
Surface & Dimensional Inspection
Our SI3100 Surface Defect Detector provides a complete inspection that locates and judges any defects to the precision of a single square millimeter. Recommended for inspecting the full circumference of your 3D printer filament, this detector captures images that can be easily digitally shared or printed for further review by technicians.
Dimensional Inspection
Specifically designed for detecting lumps or neckdowns that are not visible on the surface, Taymer’s LN3800 Lump and Neckdown Detector is able to capture images that identify any variation within the diameter of your 3D printer filament. We also provide software that will assist technicians in inspecting any lumps or neckdowns, as well as assessing whether action is required.

Inspection Systems for Filament Extrusion
SI3100 Surface Defect Detector
Detects and classifies surface defects around the full circumference of extruded filament, down to one-square-millimeter precision. Captures inspection images for review or digital record-keeping.
LN3800 Lump & Neckdown Detector
Measures filament diameter continuously to catch lumps and neckdowns invisible to surface inspection alone. Includes software for technicians to review flagged sections and confirm pass/fail decisions.
Materials We Inspect
Our machines are well-suited for inspecting a wide variety of different 3D Printer filaments, including popular materials such as:
- ABS (Acrylonitrile Butadiene Styrene)
- ASA (Acrylonitrile Styrene Acrylate)
- CF Nylon
- HIPS (High Impact Polystyrene)
- Nylon
- PC (Polycarbonate)
- PEEK (Polyether Ether Ketone)
- PETG (Glycol-modified Polyethylene Terephthalate)
- PLA (Polylactic acid)
- TPU (Thermoplastic polyurethane)
Consistent, Spec-Compliant Filament, Every Spool
Taymer has supported extrusion manufacturers for over 60 years with inline quality inspection systems built for wire, cable, pipe, tube, and filament production. Contact our team to discuss which inspection system fits your filament line.
Frequently Asked Questions
What causes defects in 3D printer filament?
Filament defects typically come from inconsistent diameter control, surface contamination, or extrusion temperature fluctuations during manufacturing — resulting in lumps, neckdowns, or surface flaws that can cause print failures or printer damage.
How is 3D printer filament quality inspected during manufacturing?
Inline inspection systems, like Taymer’s SI3100 and LN3800, measure filament diameter and inspect surface quality continuously as the filament is extruded, flagging out-of-tolerance sections before they’re spooled.
What materials can Taymer’s filament inspection systems handle?
Taymer’s systems inspect a wide range of filament materials including ABS, ASA, CF Nylon, HIPS, Nylon, PC, PEEK, PETG, PLA, and TPU.
Does Taymer make inspection equipment for other extrusion applications besides filament?
Yes — Taymer manufactures inline inspection systems for wire and cable, pipe and tube, and 3D printer filament extrusion lines, in addition to metal, fiber, medical, and packaging applications.
