Why this chamber

Not the vacuum chamber you find on Amazon

01

Fits the big spools

We had it custom designed extra large, so it fits 5, 10 and 20 kg spools. Most chambers sold online aren't big enough.

02

Thick stainless steel

Customers have sent us photos of cheap chambers that imploded under vacuum. This one is thicker, high-quality stainless.

03

Doubles as storage

Leave dried spools under vacuum until you print. No air, no moisture, ready when you are.

How to use it

Bake, vacuum cool, print

The same process we use before every print of ULTEM, PEEK, PPS and polycarbonate on our shop floor.

01

Bake the spool

The day before, bake the spool in your oven at the manufacturer's drying temperature.

02

Cool it under vacuum

Turn the oven off, move the spool into the chamber and pull a full vacuum. It cools overnight with no air around it.

03

Straight to the printer

In the morning, chamber to preheated printer in 30–60 seconds. Watch the first purge: smooth and glassy means print.

FAQ

Before you buy

Do I need an oven too?

Yes. The chamber and pump handle the vacuum step. You bake the spool first in any oven that can hold your material's drying temperature. If you don't have one, the vacuum oven does both.

What size spools fit?

The 5.5 gallon chamber is extra large, so it fits big 5, 10 and 20 kg spools, which most vacuum chambers sold online can't hold.

Is the pump oil included?

Yes. The kit comes with the vacuum pump, pump oil, chamber, lid with silicone seal, valve, pressure gauge and hose.

What temperature do I dry PEEK and ULTEM at?

Most ULTEM around 120ºC and PEEK 120–140ºC, but check the data sheet for your spool. See the full drying guide for every material.

Can I store filament in it?

Yes. Leave dried spools under vacuum until you print. It keeps moisture out between jobs.

How do I know the filament is dry?

Watch the first purge. Steam or bubbles means it's still wet; a smooth, glassy strand means you're good to go. More in the drying guide.

Dry first

Dry it right before you touch a single setting

Drying filament right is the single highest-leverage thing you can do for print quality. The chamber and pump make the vacuum step easy.
