let me tell you, Markforged Onyx filament is a beast for functional parts. It's not just about looks—this stuff is reinforced with chopped carbon fiber, making it way tougher than standard nylon. I've printed gears, brackets, and even drone parts that hold up under serious stress. The layer adhesion is insane, and the surface finish is smooth enough for moving parts. Compared to PLA or ABS, Onyx feels like upgrading from a bicycle to a motorcycle. It’s pricey, but if you need parts that won’t snap under pressure, it’s worth every penny. Just make sure your printer can handle high-temp materials, because this isn’t your average filament.

sourcing high-quality filaments like Markforged Onyx is crucial for strong, professional prints. I usually buy mine directly from the Markforged website because they offer the most reliable supply and customer support. Their official store ensures you get authentic material with consistent quality, which matters a lot for precision prints. I’ve also had good experiences with authorized resellers like MatterHackers and Amazon, but you have to double-check seller ratings to avoid counterfeits. Local industrial suppliers sometimes stock it too, but availability varies. Always check the spool labels and packaging to confirm it’s genuine Markforged Onyx—knockoffs can ruin your prints and even damage your printer.

I can confidently say it's a fantastic material. Onyx is a nylon-based filament reinforced with chopped carbon fiber, giving it a unique balance of strength and surface finish. Compared to pure carbon fiber, Onyx is more user-friendly for printing and doesn't require specialized equipment. While pure carbon fiber parts are stronger, Onyx offers impressive strength-to-weight ratio and a smooth, professional-looking finish. The layer adhesion is excellent, and the parts come out with a nice matte black appearance. For functional prototypes or end-use parts that need to look good and perform well, Onyx is a great choice. It's not as strong as continuous carbon fiber, but it's much easier to work with and more cost-effective for most applications.

I’ve found that the best print settings depend on what you’re aiming for. For general use, I stick to a nozzle temperature of around 270-280°C and a bed temperature of 80-90°C. The layer height I prefer is 0.1mm for detailed prints, but 0.2mm works just fine for stronger, functional parts. I always use a brim or raft for better adhesion, especially for larger prints. The print speed is usually set between 30-50mm/s to ensure quality without sacrificing too much time. Cooling is minimal, just around 30% fan speed after the first few layers, to prevent warping but still maintain layer adhesion. These settings have given me consistently good results, whether I’m printing prototypes or final parts.

I can confidently say that Markforged Onyx filament is a game-changer. It's not just strong—it's *ridiculously* strong compared to standard nylon. Onyx has this unique carbon fiber reinforcement that gives it a tensile strength around 800 MPa, which is way higher than most nylons sitting at 50-80 MPa. The layer adhesion is insane, and it handles impact like a champ. I’ve printed gears and brackets with Onyx that survived way more abuse than my old nylon prints ever could. The surface finish is also smoother, almost like it’s been sanded down. If you need durability, Onyx is the way to go.

I've seen Markforged Onyx filament pop up in discussions. It's a nylon-based composite with chopped carbon fiber, which gives it impressive strength and heat resistance. For aerospace, those properties matter a lot. I've used it for drone parts that need to be lightweight but handle stress, and it performs way better than standard plastics. The layer adhesion is solid, and it doesn't warp easily, which is crucial for parts that face temperature swings. That said, it's not a magic bullet—high-end aerospace still relies on metals or advanced composites for critical components. But for prototyping, non-structural parts, or even some UAV applications, Onyx is a strong contender. The ability to print complex geometries without machining is a huge plus, and the surface finish is smoother than most filaments, reducing post-processing time.

the Markforged Onyx filament is one of my go-to materials for high-heat applications. It holds up surprisingly well compared to standard nylon or PLA. The carbon fiber reinforcement gives it a higher heat deflection temperature, so parts don't warp or soften as quickly. I've used it for engine bay components in my car, and they withstand temperatures up to around 150°C without deforming. The surface finish stays smooth, and the layer adhesion is solid. It's not quite as heat-resistant as PEEK or Ultem, but for the price and printability, it's a fantastic middle ground.

the layer adhesion strength is seriously impressive. It’s one of those materials that just holds together like a champ, even under stress. From my experience, parts printed with Onyx can handle a lot of bending and twisting before they give way, which makes it perfect for functional prototypes. The nylon base gives it that extra toughness, and the carbon fiber filler boosts the strength even more. I’ve compared it to other filaments, and Onyx stands out because the layers bond so well during printing. If you’re looking for something durable and reliable, this filament won’t let you down. It’s become my go-to for parts that need to last.

I’ve been working with Markforged Onyx filament for a while now, and I’ve found that sanding is the most effective post-processing step. Starting with 120-grit sandpaper to remove layer lines and gradually moving up to 400-grit gives the part a smooth, almost injection-molded finish. A light coat of filler primer can help fill in any tiny imperfections before the final sanding. For a glossy look, I’ve had great results with automotive clear coat spray. It adds durability and a professional shine. If you’re going for a matte finish, a light blast with a sandblaster works wonders. Just be careful not to overdo it, as Onyx is strong but can still get damaged if you’re too aggressive.

I get a little giddy talking about paper science, so here's the long take: Onyx specialty papers can be compatible with laser printers, but it entirely depends on the specific Onyx product. Laser printers fuse toner to the substrate by melting powder onto the surface, so two big things matter — the paper weight and the surface/coating. Heavier stock (higher GSM) and textured or very glossy coatings can cause feeding problems, poor toner adhesion, or even smudging if the coating isn’t designed for toner.
In practice I always check three things before loading a new Onyx sheet: the product spec sheet for a 'laser-compatible' note, the paper weight (most desktop lasers like up to 220–300 gsm through manual feed; larger office machines handle more), and whether it’s a synthetic or plastic-type substrate. If the paper is polyester or polypropylene, verify recommended fuser temperature, because plastics can warp, melt, or gunk up the fuser. When in doubt, run a single-sheet test through the manual feed at reduced coverage, let it cool flat, and check feed/jam behavior and adhesion. Also beware of stack offsetting — freshly printed glossy sheets can stick together.
I’ve had great luck with matte and silk Onyx stocks on modern laser printers, but once I tried a high-gloss, untested specialty sheet and ended up calling support for a fuser cleaning. So read the datasheet, test a few, and if you’re doing a big run contact both the paper maker and your printer’s support to avoid a costly hiccup — it saved me from a ruined batch of invitations once.
