Composite Tooling 3D Printing Opens a US Shop

Composite tooling 3D printing now has a North American service address. On October 1, 2026, Aerospace Manufacturing reported that Massivit is expanding RapidWings with Artek in Portland, Oregon, for aerospace and defence customers. The offer is large molds and prototypes, not a desktop printer. If a program is waiting on a tool, the question is which of the company's lead-time claims belong in the schedule.

What's Happening

Aerospace Manufacturing reported on October 1, 2026 that RapidWings will provide large-format tooling services at Artek's Portland facility. The collaboration is meant to complement RapidWings work already running elsewhere, including earlier launches in Europe, and to give North American aerospace and defence customers a local place to order tools, prototypes, and demonstrations. Massivit chief executive Yossi Azarzar described the Artek site as part of that wider platform, aimed at programs whose demand has outrun older tooling capacity. Artek chief executive Sam Reiser said isotropic tools made in an additive route are a faster way to get tooling done, and that the shop wants to shorten lead times for U.S. manufacturers.

The process at the center of the announcement is Cast-In-Motion, or CIM. Aerospace Manufacturing says CIM combines additive manufacturing with dual-component materials, co-developed by Sika and Massivit, to produce large isotropic moulds, masters, jigs, fixtures, and mandrels for hollow composites. The published contrast is with modelling foam, tooling board, and printed thermoplastics. CIM tools are described as autoclave-ready across a range of temperatures, with dimensional stability, thermal resistance, adhesion, and surface quality called out as material properties. The company says the moulds withstand hundreds of cycles and that the service can reduce tooling time by 90 percent, moving lead times from months toward days. Those schedule and cycle-life figures are Massivit's claims as reported. They are not measurements taken for this article.

Services listed for the Portland operation run from design and digital tooling through tool finishing and prototypes. No machine count, no price list, and no named customer part shipped from Oregon appear in the report. What is new on October 1 is the service footprint: a U.S. shop where an aerospace or defence team can ask for this class of tool without sending the job offshore.

Why Composite Tooling 3D Printing Matters for Shops

On a composite airframe or drone shell, the mold is often the long pole. Pattern making, tooling board, and metal dies take calendar time before the first ply goes down. A printed near-net tool does not remove design, cure validation, or machining of the mold face. It can remove the wait for a carved block if the process holds shape through the cure the part needs. That is the shop problem RapidWings is selling, and it is a different problem from printing the flight article itself.

Portland matters because tooling jobs stall on shipping and on who may touch the tool. A local cell lets a program check surface, heat, and cycle life on a coupon tool before it commits a production mold. It does not qualify a flight part. Customer process specs and the cure recipe still sit with the airframer. Treat the October announcement as capacity and geography. Treat cure approval as a separate gate.

Smaller shops feel a related split. Many fixtures and trim jigs never see an autoclave. Those can be printed in-house on a desktop fiber machine and used the same week. A skin mold that must stay in tolerance at cure temperature belongs in a large-format tooling process like the one Artek is standing up. Mixing those two jobs on one purchase order is how schedules slip.

How Composite Tooling 3D Printing Compares with Older Routes

Use this as a sorting table. The RapidWings row repeats company statements from the October 1 report. It is not a lab result.

Route	What you are making	What to verify before you schedule it
Tooling board, foam, or a machined metal die	The mold or pattern	Lead time is often months; scrap and spindle time sit in the tool, not the part
Massivit CIM via RapidWings in Portland	Large isotropic moulds, masters, jigs, fixtures, mandrels	Company says about 90% less tooling time and months-to-days leads; ask for the baseline tool and the cure spec
Printed fiber-reinforced thermoplastic molds (published lab work)	Out-of-autoclave tools with embedded heat	Billah et al. (2021) reached about 100°C on PC tools; wires and voids cut strength
Desktop continuous-fiber printing	The bracket, fixture, or jig itself	Right for loaded polymer parts on a bench; wrong tool path for an autoclave skin mold

What the Research Says

Billah and colleagues at Oak Ridge printed the object RapidWings is talking about: the mold, not the skin (Billah et al., 2021). A large pellet extruder with a wire co-extrusion head embedded heaters in polycarbonate tools filled with 20 percent carbon fiber or 20 percent glass fiber by weight. Joule heating held mold surfaces near 100°C for both materials. Along the bead, ultimate tensile stress was 105 megapascals for the carbon-fiber mix, 73 for the glass-fiber mix, and 64 for neat polycarbonate. Voids and the wires themselves cut strength. The authors still judged stiffness high enough for out-of-autoclave molds. That is a measured temperature and a measured strength drop, not a promise that every printed mold survives an autoclave.

Vanerio, Guagliano, and Bagherifard reviewed large-format processes above typical desktop volumes, which they note are commonly under one cubic meter (Vanerio et al., 2024). Tooling sits on their list beside aerospace, automotive, marine, construction, and energy. Their core claim is that large-format additive manufacturing cuts lead time, cost, and material waste, and that those savings grow as parts get bigger. They also flag unresolved issues: rate versus resolution, properties, and finishing. A Portland service cell is one commercial answer to the lead-time point. The review does not certify CIM, or that 90 percent figure.

Frequently Asked Questions

What is composite tooling 3D printing?

It means using additive manufacturing to make the mold, master, jig, or fixture that shapes a composite part, instead of machining that tool from board or metal. Massivit's RapidWings service with Artek in Portland uses a cast-in-motion process the company says yields large isotropic tools. The mold is what gets printed. The flight part is still laid up on it.

Does the RapidWings Oregon site cut tooling time by 90 percent?

That 90 percent figure is Massivit's claim, reported by Aerospace Manufacturing on October 1, 2026, not a number from an independent test in this article. The company also says conventional tooling lead times of months can fall to days. Ask Artek which tool, which cure cycle, and which baseline those comparisons use before you put them in a schedule.

Can a desktop fiber printer make an autoclave mold?

Not the mold RapidWings is selling. Autoclave tools are large, must hold a surface through heat and pressure, and are usually machined after a near-net print. A desktop continuous-fiber machine is for brackets, fixtures, and other loaded polymer parts. Print the shop aid on the bench, and send the skin mold to a large-format tooling process.

Fibricate's Place in This Story

Fibricate is not a mold bureau, and RapidWings is not a desktop. The connection is fiber, at two different scales. A shop that needs a loaded bracket or a drill jig this week can print it on a desktop continuous carbon fiber 3D printer — the FibreSeeker 3, with a 300 by 300 by 245 millimeter volume — using a continuous carbon fiber spool in the bead. That part is the deliverable. It is not a tool you would drop into an autoclave to cure a wing skin. When the deliverable is the mold, the October 1 news points at a service process in Portland, with company claims you should pin to a specific cure. When the deliverable is a strong polymer part on a bench, desktop continuous fiber is the relevant machine. Keeping those orders apart is the whole point.

What to Watch Next

Watch for a named tool out of the Artek cell: resin system, cure temperature, cycles actually run, and how the surface was finished. Hundreds of cycles and a 90 percent time cut are useful only beside that record. Also watch whether European RapidWings sites and the Oregon site quote the same process window.

Over the next one to two years, large-format tooling will keep splitting into print-the-mold and print-the-part. Drone and airframe rates are what Massivit cites as the demand. Printed thermoplastic tools in the lab held about 100°C and still lost strength where wires and voids sat. Anyone booking Oregon time should ask which side of that split the drawing is on.
