When you print at volume, the filament invoice is only part of the cost. Inconsistent diameter, batch-to-batch colour drift, moisture in transit and slow restocks all turn into failed parts and machine downtime. As a European manufacturer — not a reseller — we control quality at source and ship quickly within the EU, so the filament you qualify today behaves the same on your hundredth spool.

Made in Spain ISO 9001 & ISO 14001 REACH compliant Batch consistency Custom colour & material Fast EU dispatch

Why source from a manufacturer, not a reseller

Buying direct from the factory unlocks things a trading company simply cannot offer: tighter diameter tolerance, batch traceability, custom formulation and colour matching, and a single technical contact who understands the material. It also removes a markup layer, so your per-kilogram cost reflects production, not resale.

Quality controlled

Tight diameter tolerance and quality checks on every production run for an accurate, reliable, jam-free extrusion process.

ISO certified

Manufactured under ISO 9001 and ISO 14001 processes, with REACH-compliant materials and documentation on request.

Custom colour & material

Bespoke colours matched to RAL/PANTONE references, and tailored material formulations for specific industrial applications.

Technical support

Direct support from the people who make the filament — print profiles, datasheets and material selection guidance.

Materials available at scale

Our full material range is available in bulk and large-format spools, in 1.75 mm and 2.85 mm where applicable. Many grades are certified for food-contact, skin-contact and toy-safety applications — useful for regulated production.

Bulk & large-format spools

Most of our filament is available in larger spool weights to cut changeovers and lower your cost per kilogram. Standard retail spools are 1 Kg; for production we offer larger formats and volume pricing. For continuous runs and print farms, fewer, larger spools mean less downtime swapping reels and more consistent colour across a job.

Format Best for
1 Kg spools Standard production, colour variety, prototyping
2.5 Kg spools Reduced changeovers, steady-volume printing
5 Kg & large-format spools Print farms, long runs, lowest cost per kilogram

The European advantage

For buyers in Spain and across the EU, sourcing locally changes the total landed cost. There are no import duties or customs delays, lead times are short, and shipping is fast and predictable. You also get documentation, invoicing and support in your language and time zone — and the reassurance of a manufacturer you can visit and audit.

Custom colours & tailored materials

Industrial buyers rarely want only stock colours. We produce custom colours on request, matched to your RAL or PANTONE references, and can develop tailored material formulations for specific applications — corporate colour matching, product-line consistency, or performance requirements. For large or recurring orders, a dedicated colour or formulation keeps every batch identical across your production.

Need parts made, not filament? Use our printing service

If you need finished parts rather than raw material, our 3D printing service produces them for you — send your file and we print, finish and ship. It's a fast route for prototypes, low-volume production and one-off industrial parts without buying or running the equipment yourself.

Frequently asked questions

What is the minimum order for bulk filament?
Bulk and volume pricing depends on the material, format and quantity. Tell us what you need and we will put together a quote — contact us to discuss volumes.
Can you match a custom colour?
Yes. We produce custom colours matched to RAL or PANTONE references and can develop tailored formulations for specific applications. See colour on request.
Which spool sizes do you offer?
Standard 1 Kg spools, plus 2.5 Kg, 5 Kg and large-format options on many materials. See the spool size guide for dimensions and AMS compatibility.
Do you provide datasheets and certifications?
Yes. Technical datasheets (TDS) and safety datasheets (SDS) are available for our materials, along with ISO and REACH documentation on request.
Do you ship across the EU?
Yes. As a Spain-based manufacturer we ship quickly across Spain and the EU with no import duties, and we supply selected markets beyond the EU. Ask us about your region.
Can you supply printers and training too?
Yes. We supply 3D printers and scanners alongside filament, and provide onboarding, training and ongoing support to get your team productive. We can also produce parts for you through our 3D printing service. Book a free consultation to plan a full setup.
