BVOH Filament –1KG Kexcelled K6™ 1.75mm

Support more material combinations and shorten cleanup with fast-dissolving, water-soluble supports for complex prints.

Support PLA, PETG, ABS, and TPU

Kexcelled K6 BVOH bonds with PLA, PETG, ABS, and TPU, giving you soluble-support options beyond PLA-only workflows. Use it for overhangs, internal channels, and detailed models across these build materials.

Faster Water Dissolution Than Conventional PVA

Formulated to dissolve rapidly in tap water, K6 BVOH shortens soaking time compared with conventional PVA. Supports can be peeled away where accessible or dissolved in water to simplify cleanup around intricate features.

Removing supports from delicate overhangs, internal channels, and hollow models can mean damaged details or material left where tools cannot reach. BVOH filament from Kexcelled’s K6™ series replaces difficult manual cutting and peeling with water-soluble support removal. It holds complex features during printing, then dissolves in tap water so you can clean accessible internal spaces without reaching every support with pliers. This makes it useful for intricate functional prototypes and detailed models where manual support removal risks damaging the finished part.

K6 BVOH supports PLA, PETG, ABS, and TPU, giving you options beyond a PLA-only support workflow. Its formulation dissolves faster than conventional PVA, helping shorten soaking time and post-processing. Accessible supports can also be peeled away before soaking to reduce the amount left to dissolve. This 1.75 mm filament requires a compatible multi-material setup with external feeding and moisture protection during printing; Bambu Lab AMS is not supported.

BVOH Filament – Kexcelled K6™ 1.75mm Overview

A PVA alternative for mixed-material support workflows

For users printing with PLA, PETG, ABS, or TPU who want shorter support-removal soaking times, Kexcelled K6 BVOH is an alternative to conventional PVA. Kexcelled identifies faster water dissolution as a key difference, making it worth considering when post-processing time is a priority. For simple parts with easily accessible supports, breakaway material may remain the more straightforward workflow because it avoids a water-removal step. When switching from an existing PVA profile, tune processing settings and support adhesion for the selected build material rather than assuming the same profile will transfer unchanged.

Frequently Asked Questions About BVOH Filament – Kexcelled K6™ 1.75mm

Which materials can Kexcelled K6 BVOH support?

Kexcelled lists PLA, PETG, ABS, and TPU as compatible build materials.

How quickly does this BVOH filament dissolve?

K6 BVOH as faster-dissolving in tap water than conventional PVA and advertises dissolution within 30 minutes.

Why does BVOH filament string, and how should I keep it dry?

Moisture can cause stringing and unstable extrusion. Print from a compatible dry box or filament dryer, reseal the spool with effective desiccant after use, and dry wet filament using a Kexcelled-confirmed cycle. BVOH and PVA need similar moisture control, but drying presets are not automatically interchangeable; K6-specific drying settings still require confirmation.

Heat creep is another possible cause of jams: heat travels above the melt zone, softening filament before it reaches the nozzle. A hot chamber, inadequate heatsink cooling, or extended hot idle periods between material changes can increase the risk. For PLA builds, open the enclosure door or use the printer’s approved ventilation settings to reduce chamber heat. Check that the hotend heatsink fan works and its airflow is unobstructed; increasing the part-cooling fan is not a substitute. Reduce the BVOH nozzle temperature within Kexcelled’s 200–240°C (392–464°F) range if extrusion and support adhesion remain reliable, and use printer-supported standby cooling for an idle nozzle.

Do not automatically open the chamber for ABS builds, which need thermal stability to limit warping. If feeding still fails, also check moisture, filament-tip shape, purge settings, and the filament path. Clear an existing blockage using the printer manufacturer’s procedure rather than forcing filament through it.

Can I use K6 BVOH with Bambu Lab AMS?

No. Kexcelled K6 BVOH is too soft for reliable automatic feeding and retraction in Bambu Lab AMS and should not be loaded into it. Use a compatible external-feed setup that keeps the spool dry during printing.

Support FAQ

What Should I Buy from Call3D?

Call3D is particularly valuable when you are looking for:

Carefully selected third-party accessories, mods, and upgrades for Bambu Lab printers;
Compatibility-sensitive parts that require clearer model, version, or installation guidance;

Call3D Store & Service Reviews

Found this shop on Reddit, chatted with a real person about the P2S filter I needed. Asked if they could ship to SG, they checked and made it happen! Super happy because this filter is basically impossible to find locally and always out of stock everywhere else. Fast, friendly, and solved my problem perfectly. Will buy again!

When EP invited me to Shenzhen back in 2019, I was absolutely blown away by the hardware innovation coming out of China. Just one year later, Bambu Lab burst onto the scene—and their solutions have grown right alongside Bambu, evolving from the very beginning to where they are today.

Bought a ventilation system but changed my mind last minute. I thought returns would be a huge hassle, but they told me there’s a return warehouse in Houston only about a 10-minute drive from where I live in Missouri City. Drove over and returned it super easily. Super convenient return process, great experience overall!

It's quite durable and works well overall. Compatibility has been good, too.

This is very difficult to use.

It arrived well packaged. I dried it in the AMS at 65°C for 18 hours before printing, and the results were pretty good. The supports took a very long soak to dissolve completely, but the finished print looked better than when I removed regular supports made from a different material.

The model is a good match, the build quality is very good, and it fits the printer perfectly.

This works really well for printing shoes and similar items, and it dissolves in water.
