Can't use our recycled products due to your Standard Operating Procedures, or simply want to support a good cause? Donate your points to charity! Knightcycle is building a program to partner with UK-based charities that use 3D printing. Your donated points will help reduce their material costs and support their important work.
Charities: Interested in joining our points donation program? Email info@knightcycle.co.uk. Businesses: Know a charity that should be included? Encourage them to reach out to us directly.
Yes! You can send up to 30kg in a single box. A small per-kilogram surcharge applies to cover additional delivery costs, payable before collection is arranged. This option is ideal if you frequently print with high infill densities or have accumulated heavier waste.
Your startup sale subscription price is locked in for as long as you remain an active subscriber. If you cancel and resubscribe later, the current pricing at that time will apply.
You have the option to upload your company logo and preferred URL link to our 'Our Recycling Partners' section on our website. We are proud to showcase each subscribed company that has championed recycling their filament waste, and we wish to direct customers to these outstanding companies and individuals.
Your company dashboard shows the total weight of PLA waste you've sent to Knightcycle. Filament production figures are calculated monthly, based on the average recycled content across all production that month, multiplied by your contributions. This provides an accurate estimate of your recycled filament while allowing us to manage batch processing efficiently as a small operation. Production figures are updated with a one-month delay to ensure calculations are correct.
For larger businesses generating significant waste on a regular basis, it may be possible to provide more precise production figures specific to their contributions.
If you want to save money, ensure your waste is genuinely recycled, and support the 3D printing community, let's have a conversation.
