3D printing materials supplier Polymaker has launched Fiberon PA612-ESD filament engineered to be used in industrial settings the place each mechanical sturdiness and electrostatic discharge (ESD) safety are required.
The filament is formulated with a nylon 612 base bolstered by carbon nanotubes (CNT) and carbon fibers, making a conductive construction that safely dissipates static costs. This inner conductivity allows distinctive capabilities, together with compatibility with capacitive touchscreens. Designed for electronics manufacturing environments, the fabric is fitted to printing housings, jigs, and fixtures which might be uncovered to static-sensitive circumstances.
Along with ESD safety, the filament presents thermal and mechanical stability, sustaining its form beneath high-temperature processes similar to solvent baking. It has a warmth deflection temperature of 157°C at 0.45 MPa, supporting functions that require sustained dimensional accuracy beneath thermal stress.
Detailed specs present materials conduct in use
Polymaker has disclosed detailed efficiency information for the filament, noting variation in mechanical properties based mostly on printing orientation and environmental moisture. Underneath dry circumstances, the filament achieves a tensile energy of 84.3 MPa within the X-Y course and 21.5 MPa within the Z course.
Publicity to moisture reduces these figures to 73.6 MPa and 19.2 MPa, respectively. Measured by Younger’s modulus, the fabric’s stiffness additionally declines in humid circumstances from 4293.7 MPa dry to 3730.8 MPa when moist. Affect energy and bending modulus present comparable shifts, with Charpy notched affect energy measured at 5.9 kJ/m² in dry circumstances and 4.9 kJ/m² when moist.
{The electrical} efficiency of printed components could be adjusted via course of settings. Floor resistivity improves at larger nozzle temperatures, with the most effective outcomes seen between 300°C to 320°C.
The filament prints with out requiring a heated chamber, although a mattress temperature of 40°C to 50°C is really useful. As a result of abrasive nature of the fabric, commonplace brass nozzles put on shortly. Polymaker estimates a lifespan of roughly 9 hours and customers are suggested to make use of hardened options for sustained printing.
Fiberon PA612-ESD is appropriate with breakaway helps designed for nylon-based filaments similar to PA12, enabling advanced geometries with out counting on soluble supplies. It’s out there in a 1.75 mm diameter and supplied in spool sizes of 500 g and three kgs.
ESD-safe supplies for electronics manufacturing
Additive manufacturing is being leveraged to develop and deploy specialised ESD-safe supplies that enhance agility, security, and efficiency in electronics manufacturing.
In keeping with this, Arizona-based 3D printing firm Mechnano partnered with ceramic AM supplies supplier Tethon3D to develop C-Lite, a inflexible, high-temperature resin designed for 3D printing ESD-safe components utilizing LCD, DLP, and SLA methods. The fabric incorporates Mechnano’s proprietary MechT carbon nanotube expertise, which isolates and evenly disperses CNTs to allow constant static dissipation and overcome widespread agglomeration points.
C-Lite is engineered to endure repeated wave soldering cycles at 245°C, with checks displaying no shrinkage, warping, or dimensional modifications after 50 reflow passes. Aimed toward electronics producers, the resin helps the speedy manufacturing of customized carriers, jigs, and tooling for reflow processes and different static-sensitive environments.
Elsewhere, Netherlands-based impartial 3D printing resin producer Liqcreate launched Liqcreate ESD, a black photopolymer resin developed to be used in electronics manufacturing and static-safe work environments. Designed for compatibility with resin printers utilizing DLP, MSLA, SLA, and LCD applied sciences inside the 385-420 nm wavelength vary, the fabric combines isotropic electrostatic discharge safety with mechanical sturdiness.
Its floor resistivity stays constant throughout all printing instructions, making certain dependable antistatic efficiency. As soon as post-cured, printed components retain their type even when softened above their warmth deflection temperature, making the resin appropriate for producing customized enclosures, jigs, and manufacturing facility instruments.
