SUNLU Silk PLA+ metallic 1.75mm 1kg

If you want a 3D print finish with a noticeable metallic silk look, the SUNLU Silk PLA+ filament is a strong choice for FDM printing. It is designed to combine PLA Plus ease with a deeper, shiny metallic lustre and a smooth layered feel, so your models look more refined straight off the printer. It is also made for stronger, tougher results, which matters when you are printing functional items like durable phone case styles or cosplay armour pieces. 🧵

The essentials

SUNLU Silk PLA+ is a PLA Plus filament with an added metallic, silk-like visual effect. Compared with basic silk filament types, the intended outcome is a deeper metallic shine and a silkier layered surface feel when the print is finished. Because it keeps the classic PLA Plus advantages, you can approach it with confidence if you have already had success using PLA Plus materials in your workflow. ✨

There is also a subtle light shifting effect built into the appearance. As your model catches light, it can show elegant colour changes between tones, described as light gold or silver shifts similar to molten jewellery. That makes it a good fit for decorative pieces where visual impact is part of the purpose. It is a filament you will likely appreciate when you want the surface to look special without needing heavy post finishing.

Key features

The silk smoothface concept is paired with PLA Plus performance characteristics. In practical terms, you are looking for strong layer bonding and a printing experience that stays straightforward. The manufacturer also highlights tough performance, with the material described as bending without snapping, which supports more resilient prints for wearable or everyday use. 🛡️

Printing is specified as beginner-friendly on most FDM printers, with a stated nozzle temperature of 205°C. The aim here is smooth flow through the nozzle and fewer clogs during typical runs, which can save time on troubleshooting. If you are planning larger projects, the predictable feed and clean behaviour are the kind of details that help you keep momentum.

Another stand out is the material effect. The filament is presented as metallic silk with a dynamic metal look so the model changes character depending on how it is lit. Even if you mostly care about build quality, this visual layer can make prints feel more premium to look at.

You also get presentation and handling support. The spool is vacuum packed in a moisture lock bag, and the listing states it includes a filament clip and desiccant. That matters for silk type filaments, because controlling moisture helps protect the consistency of the print surface over time.

What to know before you buy

It makes sense if you want metallic silk style results, especially when you are printing pieces where surface appearance is a key part of the final outcome. It also suits use cases where durability and flexibility are beneficial, such as cosplay armour shapes or more robust phone case concepts. If your priority is a purely matte finish, or you prefer the look of standard PLA without metallic shifts, you may find this not quite aligned with your goals.

It may not suit you if your printer setup cannot reach the stated printing temperature, or if you rely on very specific slicer tuning that you have only tested with other materials. Keep in mind that silk effect filaments can be more sensitive to moisture, so the vacuum packed storage and included desiccant are there for a reason. For best results, treat it like a premium silk PLA Plus material, store it carefully, and plan your print settings around smooth nozzle flow. 🧊
