Build in public: ReExtrude is currently in active prototype development. Real testing, measured results and corrections will be published progressively.

PRINTABLE INDUSTRY

Desktop recycling ecosystem

Turn failed prints into new material.

ReExtrude is a modular, printable workflow designed to transform correctly sorted 3D-printing waste into flakes, recycled filament and a new print — from rPLA to rPETG, rASA and other validated material streams.

Prototype in active development

Failed prints are not the end of the material.

Most printing waste is treated as unusable because the steps required to sort, prepare and reform it are fragmented, expensive or difficult to understand.

Waste

Supports, failed parts and old prototypes accumulate quickly.

ReExtrude is designed around known, separated material streams rather than an unrealistic “throw everything in” promise.

Loop

A complete workflow instead of one isolated machine.

The project connects material preparation, shredding, drying, extrusion, validation and reprinting into one understandable system.

One loop. Three machines. Five controlled stages.

The goal is not simply to melt plastic again. The goal is to control each stage well enough to understand what enters the process and what comes out.

01 — SORT

Separate materials

PLA, PETG, ASA and other polymers must remain separated. Unknown blends and contaminated waste do not belong in the same batch.

02 — SHRED

Create controlled flakes

Reduce failed parts, supports and used prints into a geometry suitable for drying and extrusion.

03 — DRY

Control moisture

Prepare the material before extrusion. Consistency begins before the polymer reaches the barrel.

04 — EXTRUDE

Form new filament

Melt, push, cool and guide the material while monitoring the parameters that influence the result.

05 — VALIDATE

Test and print again

Measure diameter, inspect the filament, tune printing parameters and document the limits of each recycled batch.

Important: ReExtrude is not designed to mix different polymers together. Each batch must use a known and correctly sorted material stream.

rPLA is only the beginning.

The prefix “r” means recycled. ReExtrude is intended to support different correctly sorted thermoplastic streams as the machines and process profiles are validated.

rPLA

Recycled PLA

Failed PLA prints, supports and known PLA parts processed as a dedicated material stream.

Initial development focus
rPETG

Recycled PETG

A separate recycling stream requiring its own drying, extrusion and print-validation parameters.

Material profile to validate
rASA

Recycled ASA

Outdoor-oriented material that must remain isolated from PLA, PETG and other polymers.

Additional thermoplastics may be evaluated later, based on documented tests rather than generic compatibility claims.

No unverified performance promise

The ReExtrude ecosystem

Three complementary machines, developed as one platform. Each module is intended to remain understandable, repairable and printable by makers.

256 × 256 × 256mm target build volume

Full printable approach

Designed for the printers makers already own.

Printable components are designed around a maximum target build volume of approximately 256 × 256 × 256 mm — the size available on machines such as the Bambu Lab P1S.

This does not mean every component is printed in one piece. Large functions are divided into printable, replaceable subassemblies.

Print locallyProduce the printable parts on a standard-size machine.
Split intelligentlyLarge assemblies are divided around mechanical constraints.
Replace individuallyReprint a damaged or worn component instead of replacing a complete unit.
Use common hardwareThe BOM is designed around identifiable and accessible parts.

Printable does not mean disposable.

The machines are being designed as maintainable mechanical systems, not decorative prints. Printed parts, bearings, shafts, motors and metal hardware each have a defined role.

Modular

Independent assemblies simplify testing, repair, upgrades and replacement.

Repairable

Wear parts are intended to be identifiable and replaceable instead of hidden in a sealed machine.

Documented

Files, BOMs, assembly logic, test results and known limitations will be documented progressively.

Open design with clearly defined rights.

The files remain protected. Personal use, commercial manufacturing and authorised digital distribution are separate rights with separate licenses.

Personal use

Build it for yourself

Study, modify and manufacture the authorised files for personal, non-commercial use.

  • No resale of digital files
  • No commercial manufacturing
  • No public redistribution
Learn about personal access
Commercial manufacturing

Make physical products

A separate license can authorise a business to manufacture and sell defined physical products.

  • Production rights stated in writing
  • Digital redistribution remains prohibited
  • The manufacturer remains responsible for safety and compliance
Commercial license updates
Authorised reseller

Distribute digital files

Only specifically authorised partners may resell digital ReExtrude files under an individual reseller agreement.

  • End-customer license required
  • Approved versions and channels only
  • No second-level reseller rights
Reseller information

Built in public, released by evidence.

ReExtrude is still under construction. Public communication must distinguish design intent, prototype results and commercially authorised releases.

No finished-product theatre.

The project will show the real process: CAD decisions, printed parts, assembly, failures, corrections, measurements and repeatable tests.

PrototypeA design under evaluation. Not presented as a certified commercial machine.
Measured testA documented result tied to a specific version, material and test setup.
Commercial ReleaseA version expressly identified as eligible for the rights stated in its license.

Development roadmap

The sequence may evolve as testing reveals new constraints. Progress will be communicated through evidence, not fixed performance claims.

01 — Mechanical prototypesValidate architecture, fit, motion, wear zones and assembly.
02 — Material testsDocument sorting, flake preparation, drying and extrusion behaviour.
03 — Integrated workflowConnect the three modules into a repeatable end-to-end process.
04 — Release packagesPrepare files, BOMs, documentation, safety notes and license access.

Frequently asked questions

Clear boundaries are essential for both the project and the people who will build from it.

Can PLA, PETG and ASA be recycled together?

No. Each polymer must be sorted and processed as a separate known material stream. Mixed or unknown waste can produce inconsistent or unusable results.

Does “full printable” mean every part is plastic?

No. It means the custom printable components are designed around a common 256 × 256 × 256 mm build volume. Bearings, shafts, motors, fasteners, heaters and other appropriate hardware remain part of the BOM.

Is the system already finished?

No. ReExtrude is currently in active prototype development. The site distinguishes current prototypes from future Commercial Releases.

Can I sell the digital files?

Not under a personal or manufacturing license. Digital resale requires a specific authorised reseller agreement issued by Printable Industry.

Can recycled filament match virgin filament?

Performance depends on material history, sorting, contamination, drying, processing and quality control. ReExtrude will publish measured results without claiming universal equivalence.

Will the files include electrical certification?

No general certification is implied by the files. The final builder or manufacturer remains responsible for electrical design, safeguards, risk assessment and regulatory compliance unless a specific validated scope expressly states otherwise.
