PVA filament


From: £31.80 (£26.50 + £5.30 VAT)

Our premium quality PVA support filament is used to help create complex 3D prints as it can be printed as a solid support that can be washed away with water after printing


 iDig3Dprinting’s PVA filament  is a soluble solid infill support filament that is dissolvable in water. It is used for printing complex shapes with overhangs, bridges and intricate inner geometry on dual extruder 3D printers as it can be used as a solid infill, you simply wash it away in water after printing to reveal your finished model. Of itself, it has a high tensile strength and feels like PLA filament.

Our PVA filament comes in 0.5kg spools, the colour is natural. It is available in both 1.75mm and 2.85mm so you can use it on your BCN3D sigma or on an Ultimaker.

How to use our PVA filament

To use our PVA, water soluble, filament simply soak for a few hours, the supports can then be easily removed by hand. Alternatively, soak for 12 – 24 hours and the soluble support filament will dissolve completely. You can speed this process up by using warm water and agitating the water by hand.

NOTE: Because PVA breaks down in water, it is sensitive to high levels of humidity in the air. For best results store unused PVA filament in a sealed container with desiccant.

Why use PVA as a support filament

Commonly, when printing complex shapes the slicer software will add supports using the same material to allow the model to print out, whilst maintaining its desired shape. Unfortunately this has a number of problems.

Firstly, it will often leave marks on the model when the supports are removed. Careful post processing is then required to remove the signs of these attachments. With ABS this can be OK as it lends itself well to post processing but with something like PLA post processing is not always a good option.

Secondly, the support structure that is used does not guarantee that the models design is reproduced very well, without distortion of some sort.  Using a solid infill like PVA means that, for example, a bridge is completely supported across it’s whole surface.

Lastly, you can print far more complex geometries using a solid infill filament like PVA, the geometry is only limited by you being able to flush out the PVA with water.

  2. Free UK shipping on 3D printer filament samples.
  3. £5.40 (incl. VAT) flat rate for all UK Mainland orders under £100 (incl. VAT); Flat rate of £15.00 (incl. VAT) on Highlands & Channel Islands on orders below £100 (incl. VAT).

Orders over 2kg in weight are shipped via DHL Express orders under 2kg are shipped via Royal Mail 48hrs Tracked. The advantage of flat rate Postage and Packaging to our customers are that if you order 1, 2, 3, 4 or 5 spools of filament the price is the same. p.s. Were sorry about the Highland & Islands shipping costs, it’s a reflection on the increased shipping charges we have to pay.

International Shipping

We do ship internationally but ask if you can contact us to arrange an order as shipping costs can vary greatly depending upon destination and weight. Please see or International orders page for more information.

You can return your goods to iDig3Dprinting for any reason within 14 business days following receipt at your delivery address as long as they are in a re-saleable condition. Filaments & resins cannot be returned once opened as once exposed to air these items perish. Downloadable goods and 3D print samples cannot be returned and no refund will be issued. Shipping costs of returned items are paid by the customer A full refund will be issued for unopened items that are returned in their original packaging that are in a "as new" re-saleable condition minus additional costs that are incurred by iDig3Dprinting like payment processing fees, custom duties or charges.

All requests for refunds are subject to inspection by iDig3DPrinting of the returned item. We are not a charity or a lending library. Refunds and returns for faulty items works a bit differently. Faulty goods can be accepted for return upto 60 days from receipt of the goods (However we prefer to offer diagnostics and repair solutions prior to an actual return, its better for the environment). After this time you will need to contact the Manufacturer. A repair or replacement will be issued for faulty goods once they have passed inspection and been found by iDig3Dprinting to be faulty. This is a brief account of our returns policy. For the full terms please see our Terms and conditions page. Content on the Terms and Conditions page supersedes this content.

Great service, very quick to answer queries and resolve any problems. Reliable and affordable.
First class service and support, purchased some spare parts for my printer and they were glad to help with an unrelated problem I was having with the printer, even though it was not supplied by iDig , I would recommend them without hesitation.
Have had a lot a of problems setting up a 3d printer at our school, idig3d printing contacted me through a forum and have been brilliant ,giving advice and guidance. Thank you
