FinishXpert Filler Spray 6-pack

FinishXpert Filler Spray – Advanced surface finishing for 3D prints

FinishXpert Filler is an advanced filling spray specifically developed to improve the surface quality of 3D printed parts. Designed to work with a wide range of thermoplastic materials used in FFF and FGF technologies, this innovative formula delivers consistent, high-quality results with a filling capacity of approximately 15–30 microns per coat.

The spray comes in an elegant RAL 7042 grey and is easy to sand, making it ideal for smoothing prints produced with standard settings such as 0.2 mm layer height and 0.4 mm nozzle.

High filling power for smoother surfaces

FinishXpert Filler creates a uniform surface layer that helps reduce visible layer lines and correct imperfections. By applying 2–3 coats with intermediate sanding, you can achieve a significantly smoother and more refined finish.

The process is simple: apply a coat, sand the surface, and repeat if necessary until the desired smoothness is achieved.

Wide material compatibility

This spray is designed for versatility and works effectively with a broad range of materials, including:

PLA, ABS, PET, PETG, PP, PA and other common thermoplastics used in FFF/FGF printing.

It is also suitable for parts produced using:

• SLS technology (PA12 / PA2200)
• SLA photopolymer resins

In all cases, it helps reduce surface roughness, improve rigidity, and create a surface that is easier to sand and refine.

Perfect base for painting

FinishXpert Filler not only smooths the surface but also acts as an excellent primer layer. It improves paint adhesion and prepares the object for further finishing steps.

It can also be combined with other fillers, such as FinishXpert grey putty, to achieve even higher levels of detail and surface quality.

Application instructions

Using FinishXpert Filler is straightforward:

1. Start with a clean and dry surface
2. Shake the can thoroughly before use
3. Spray evenly from a distance of 20–25 cm
4. Allow it to dry for approximately 2 hours before sanding or painting

For optimal results, apply thin layers at intervals and sand between coats using:

• wet sandpaper (P800–P1000), or
• dry sandpaper (P600)

Important note

FinishXpert Filler is not compatible with flexible materials like TPU. Once fully dried, the coating does not retain flexibility and may crack if the part is bent.
