SUNLU PLA+ Silk 4KG filament bundle

If you want silk like colour effects with a glossy finish, the SUNLU PLA+ Silk Filament Bundle is a practical choice for everyday 3D printing. This 4 kg bundle brings together four colour variations in a silk PLA+ style filament, so you can explore richer looks without changing material. It is designed to print smoothly and consistently, helping you produce striking parts for crafts, models and display pieces.

The essentials

SUNLU 4KG PLA+ Silk Filament Bundle combines silk texture, a glossy surface and PLA+ strength in one multi spool set. According to the manufacturer, the silk PLA+ formulation offers higher durability than standard PLA, with improved resistance to impacts. The colour experience is also a key part of the appeal, since the bundle is built around four colour variations that can appear differently as the filament is rotated during printing. 😊

You also get a useful “bundle” setup, rather than buying just one spool at a time. That makes it easier to keep your workflow going when you are making repeated projects, prototypes or decorative items. It suits people who like visible colour depth and a satin, silk like look on the final surface, rather than a purely matte finish.

Key features

The filament is described as a silk PLA+ style material, with a smooth, silky texture and a vibrant colour range. A glossy surface finish is part of the design, and the manufacturer notes that polishing is not required to achieve the standout look. There is also a focus on strength and impact resistance, which helps when printed parts need a bit more toughness for handling. 🧡

One of the most distinctive ideas is the four colour effect. The bundle is presented as a silk filament with four colours, and the appearance can shift as the visible colour is revealed by the filament rotation at different orientations. This makes it especially engaging for artistic projects where you want the print to show movement, subtle variation and a dynamic colour pattern across the part.

You can also treat this as a “set and go” option, because the recommended printing ranges are provided by the manufacturer. Keeping to the stated nozzle and bed temperatures, and using the suggested speed range, is the simplest way to aim for a brighter silk finish. It is also supplied in vacuum sealed packaging to help keep moisture out during storage. ❗

Who it’s for

It’s a good fit if you want silk like surfaces with a glossy look and you enjoy colour variation from a multi colour filament set. It may not suit you if your projects need a very neutral, single tone finish, since the appearance is designed to shift with orientation and rotation. It makes sense for hobbyists who print FDM parts regularly and want a bundle that supports creative crafts and models, with strength improvements noted for PLA+.

It suits makers who are comfortable tuning print settings within the manufacturer guidance. If you prefer faster printing, take into account that the stated speed range is relatively moderate to support a brighter silk result. Worth noting, the manufacturer positions this filament for 3D printing on FDM machines compatible with 1.75 mm filament, so it is best checked against your printer setup before you start your first spool.
