3D Printing News: CymphoniK, ASA-CF Core & More
By Dynafabs
3D printing news: Polymaker's CymphoniK colour-mixing pellets, Siraya Tech's ASA-CF Core filament, ultrasound for printed concrete and new metal AM sites.
Today's 3D printing news has a strong materials flavour: a new way to mix brand colours at pellet scale, a carbon fibre filament built to stick its layers together properly, an ultrasonic trick for printed concrete, and a big new metal printing build-out in the US. Here's what happened and why it matters if you're ordering parts.
Polymaker's CymphoniK mixes custom colours from six pellets
Polymaker has announced CymphoniK, a colour mixing system for pellet-fed, large-format 3D printing. Instead of ordering a custom masterbatch for every brand colour, a studio mixes its own on site from six base pellets: cyan, magenta, yellow and black, plus white and a glass-fibre-filled "natural" PETG.
According to 3DPrinting.com's report, the first formulation is built on Polymaker's PETG-1213 R50, and the company says it has validated more than 100 colours so far, with translucent colours to follow. Mix ratios come from a web tool called CymphoniK Palette, which takes targets as CIE Lab values, RGB or CMYK sliders, or a colour picker. Palette is in a login-only pilot for now, and the system will be shown at Formnext 2026 in Frankfurt from 17 to 20 November.
Colour matching is a real headache for branded parts, so it's good to see it tackled at the material level rather than with paint.
Siraya Tech's ASA-CF Core goes after weak carbon fibre layers
Carbon fibre filaments are stiff and look great, but layer adhesion can suffer. Siraya Tech's new Fibreheart ASA-CF Core tries to fix that by putting the carbon fibre in the core of the filament and wrapping it in an impact-modified ASA shell.
All3DP's coverage says the core contains 20% carbon fibre and the filament reaches a Z-axis tensile strength of 33 MPa. It may reduce nozzle wear, though a hardened steel nozzle is still recommended. It's on sale now via Amazon, with Siraya Tech's own site to follow.
The Z-axis figure is the interesting bit. Strength between layers is usually the weak point of any FDM part, which is why we talk so much about orientation in our print orientation guide. If you're weighing up CF blends, our nylon and carbon fibre guide and outdoor materials guide cover where ASA and CF fit.
Ultrasound tells printed concrete when it's ready for the next layer
Engineers at South Korea's Ulsan National Institute of Science and Technology (UNIST) have built an ultrasonic check that shows when freshly printed concrete is strong enough to carry another layer. As 3DPrinting.com explains, it reads the concrete from one side only, so nothing presses on the soft material.
The team tested three mixes and found that the amplitude of one guided wave mode, called S0, tracked measured early ("green") strength with a coefficient of determination above 0.97 for every mix. Professor Myoungsu Shin said it could one day let a printer adjust its speed so each layer goes on once the one below has hardened enough, but stressed it has only been tested on small three-layer prints so far. The work is published in the November issue of Cement and Concrete Composites.
3D Systems and Precision Resource break ground on two metal AM sites
Engineering.com reports that Precision Resource is breaking ground on two additive manufacturing locations, in Huntington Beach, California, and Shelton, Connecticut, using 3D Systems' metal printers. The Huntington Beach site will double that location's industrial AM capacity, Shelton is its first AM site there, and both should be running in Q1 2027. The company is adding DMP Flex 350 Triple systems to its existing DMP 350 fleet, plus in-house heat treatment and more machining, to serve commercial and defence customers.
What it means if you're ordering prints
None of this changes what you can order from us tomorrow, but the direction is clear. Materials keep getting smarter about the weak spots of printing, whether that's layer bonding in CF blends or knowing when a layer is ready. For your own parts, the practical takeaways are the same as ever: pick the material for the job, think about which way the loads go, and ask if you're unsure. Our PLA vs PETG vs ABS/ASA vs TPU guide is a good place to start.
