For Onyx, you'll want a process that handles its fine layer lines and carbon fiber texture. Light sanding with high-grit paper works before a filler primer, then a gloss or matte clear coat depending on the finish you want. If you need something more durable for functional parts, a thin epoxy coating can add abrasion resistance. Speaking of things being forged, I recently got into 'Forged In The Flames', a fantasy where the protagonist literally reforges his identity and a broken kingdom from nothing, with the actual blacksmithing and political maneuvering details being surprisingly gripping.

Post-processing Markforged Onyx filament can really elevate the final product, and I’ve experimented with several methods to get the best results. Sanding is a must—I start coarse and work my way up to fine grits, sometimes wet sanding for an even smoother finish. After sanding, I often use a filler primer to seal the surface, followed by another round of fine sanding. For parts that need extra toughness, a thin layer of epoxy resin can add significant strength and a glass-like finish.

If aesthetics are a priority, painting is a great option. I’ve had success with acrylics and enamels, but adhesion promoters help the paint stick better. For a metallic look, I’ve used Rub ‘n Buff wax with great results. Another trick is vapor smoothing with acetone, though it’s tricky and requires careful control to avoid melting details. Heat gun post-processing can also help smooth surfaces, but it’s easy to warp the part if you’re not careful.

For functional parts, I sometimes machine the Onyx after printing to get precise tolerances. It’s a bit more advanced, but the material handles it well. Lastly, if you’re after a polished industrial look, a rotary tool with a buffing wheel and polishing compound can give you a mirror-like finish. Each method has its pros and cons, so it depends on what you’re aiming for.

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.

When it comes to post-processing Markforged Onyx, I like to keep things simple but effective. Sanding is my go-to, starting with 200-grit and moving up to 600 for a super smooth feel. I’ve found that a bit of elbow grease goes a long way. For a quick and easy upgrade, a few coats of spray paint can make a huge difference—just make sure to sand first for better adhesion.

If you want something more durable, try a clear polyurethane finish. It’s tough and gives the part a slight sheen. For industrial-looking pieces, a light sandblast followed by a matte sealant works great. I’ve also experimented with dyeing Onyx, but it’s tricky since the material doesn’t absorb color easily. Instead, I’ve had better luck with airbrushing details for a custom look. The key is to test small areas first to see what works best for your project.

What are the best print settings for Markforged Onyx filament?

4 Answers2025-07-28 12:26:19
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.

How does Markforged Onyx filament perform under high heat?

4 Answers2025-07-28 13:10:36
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.

How does Markforged Onyx filament compare to carbon fiber?

4 Answers2025-07-28 16:19:13
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.

What printers are compatible with Markforged Onyx filament?

3 Answers2025-07-28 07:23:59
the Onyx filament is one of my favorites because of its strength and finish. The best printers for Onyx are naturally Markforged's own, like the 'Mark Two', 'X7', and 'X5'. These printers are designed to handle the unique properties of Onyx, especially its carbon fiber reinforcement. I’ve tried third-party printers, but they often struggle with the high temperatures and precision needed. The 'Onyx One' is also a solid choice if you’re looking for something more budget-friendly but still reliable. Stick with Markforged printers for the best results—they’re built for this filament.

Can Markforged Onyx filament be used for functional parts?

3 Answers2025-07-28 20:36:23
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.

What is the layer adhesion strength of Markforged Onyx filament?

3 Answers2025-07-28 07:13:23
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.

Where to buy Markforged Onyx filament for 3D printing?

3 Answers2025-07-28 23:52:06
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.

Is Markforged Onyx filament suitable for aerospace applications?

3 Answers2025-07-28 15:19:54
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.

How strong is Markforged Onyx filament compared to nylon?

3 Answers2025-07-28 08:02:21
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.

Which onyx specialty papers work best for wedding invitations?

4 Answers2025-09-04 15:03:00
Oh man, when I’m picking paper for wedding invites I get oddly excited — there’s something magical about a heavy, dark sheet that suddenly makes gold foil pop like fireworks. My gut says start with heavyweight onyx cotton or rag paper if you want that classic, tactile luxury. Cotton/rag onyx (around 300–350 gsm) takes letterpress and deep debossing beautifully, so the impressions feel almost sculptural. It also soaks ink in a way that keeps edges crisp, which is perfect for calligraphy or delicate serif type. If you love texture, an onyx linen finish adds subtle crosshatch detail that hides fingerprints and reads as high-end without being flashy. For flashier styles, onyx metallic or pearlized cardstock is my go-to for foil invitations — gold, copper, and rose gold look insane against that deep black. Just beware: metallics can be more reflective and might show slight surface imperfections, so order samples. Smooth matte onyx works great for modern minimalist suites and digital printing with white ink; match with a vellum or metallic liner in the envelope and you’ve got a wedding suite guests will keep on their mantles.
