What happened to on-demand manufacturing marketplaces? Eight names, one pattern

Fast Radius was valued at $1.4 billion when its SPAC merger was announced in July 2021. Nine months after that merger closed, the company was in Chapter 11, and its assets sold for roughly $16 to $17 million (Techleap, Bloomberg Law).

If you assumed the "Uber for manufacturing" wave of 2013 to 2021 would end with a few big winners and some quiet acquisitions, you were half right. There were acquisitions. There were also auctions, a Chapter 7, a $3 million sale of a company that once raised $26 million, and a brand that disappeared behind a 301 redirect.

This post goes through eight companies one by one, with dates and sources, then looks at what the survivors have in common. It ends with the question that matters more than the obituaries: if the buyer on the next marketplace is an AI agent inside an editor, what does the marketplace have to look like?

The scoreboard

Eight companies that were, at some point, on the shortlist for "the platform that will win custom parts." As of October 2026:

Company	Founded	Model	Outcome	When
Plethora	San Francisco	Software-driven CNC shop, own factory	Closed, assets auctioned	Jan to Feb 2022
Voodoo Manufacturing	Brooklyn, 2015	FDM print farm, own printers	Closed, assets sold	Aug 2020, sale Mar 2021
Fast Radius	Chicago	Digital manufacturer	SPAC, Chapter 11, sold to SyBridge	2021 to Dec 2022
MakeTime	Lexington, KY	Machining network (marketplace)	Acquired by Xometry	Jul 2018
MFG.com	Atlanta, 1999	RFQ marketplace	Sold to Shapeways for $3.0M, later divested	Apr 2022
3D Hubs	Amsterdam, 2013	Marketplace, 3DP then CNC and more	Acquired by Protolabs for $280M, renamed twice	Jan 2021
Shapeways	Eindhoven, 2007	Consumer and prosumer 3DP service	Chapter 7, relaunched by founders	Jul 2024, relaunch Dec 2024
Fictiv	SF Bay Area, 2013	Manufacturing-as-a-service, own plants and partners	Acquired by MISUMI for $350M	Apr to Jun 2025

Survivors under their own name: Xometry, Protolabs (with Protolabs Network inside it) and the JLC group. Each gets a section too.

Plethora

Plethora was the San Francisco answer to "what if a CNC shop were a software company." Founded by Nick Pinkston and Jeremy Herrman, it raised more than $36 million from investors including GV and Founders Fund and ran a 57,000 square foot factory in Marietta, Georgia (Fabricating & Metalworking, Crunchbase).

The pitch was integration: software that checked manufacturability while you designed, then a factory that made the part with as little human quoting as possible. The factory was the expensive half. Plethora went through an Assignment for the Benefit of Creditors and its machinery was auctioned online by Onyx Asset Advisors, Integra Asset Solutions and Rabin Worldwide in January and February 2022 (PR Newswire). Crunchbase lists the company as permanently closed.

Some AI-generated profile sites say Xometry acquired Plethora. We found no primary source for that, and the auction notice points the other way; treat it as unverified. Pinkston tells the story himself on the Manufacturing Happy Hour podcast.

Voodoo Manufacturing

Voodoo was a Brooklyn print farm started in 2015 by former MakerBot staff, running more than 200 desktop FDM printers as one production line (Fabbaloo). The idea was that a wall of cheap printers plus scheduling software could beat an industrial machine on price for short runs.

It closed permanently in August 2020. TCT Magazine reported the reasons as COVID-19 demand loss on top of high operating costs (TCT). The physical assets were bought by 3D Printing Tech of Atlanta, reported on March 2, 2021. The scheduling software, "Voodoo OS", the part that was supposed to be the moat, was not part of the deal (3DPrint.com).

Fast Radius

Fast Radius was a Chicago digital manufacturer: production plus a software layer on top, sold under one brand. In July 2021 it announced a SPAC merger with ECP Environmental Growth Opportunities at a $1.4 billion valuation; the merger closed in February 2022 (Techleap).

In November 2022 it filed for Chapter 11. A Section 363 sale to SyBridge Technologies was approved on December 12, 2022, for roughly $15.9 to $17 million: $13 million in cash plus assumed liabilities, with job offers to 132 employees (Bloomberg Law, VoxelMatters). SyBridge said at the time it would keep the Fast Radius brand.

As of October 2026, fastradius.com redirects to sybridge.com, which does not mention Fast Radius, instant quoting or AI anywhere we could find. The brand is, in effect, retired. If you searched "Fast Radius what happened": public at $1.4 billion in February, bankrupt in November, absorbed by December.

MakeTime

MakeTime, from Lexington, Kentucky, was a pure marketplace: a network of machine shops, a Fusion 360 add-in, and a "Shop Advantage" program for the suppliers. No factory of its own.

Xometry announced the acquisition on July 10, 2018, in the same release as a $25 million funding round led by Foundry Group. The combined network went from about 1,100 to 2,300 shops, MakeTime founder Drura Parrish became Xometry's EVP of Platform, and about 30 staff joined (Xometry investor release, Technical.ly). The brand was folded into Xometry.

MakeTime is the cleanest example of a pattern you will see again: a marketplace without a factory is light enough to be bought, and the buyer is whoever already has the most demand.

MFG.com

MFG.com is the oldest name here. Founded in 1999 by Mitch Free near Atlanta, it was an RFQ marketplace: buyers posted CAD and specs, suppliers bid. Jeff Bezos invested in 2005, and the company later raised $26 million in a round led by Fidelity. Free left in 2013 (Wikipedia, SDCExec).

On April 22, 2022, Shapeways bought MFG.com's assets for $3.0 million (Shapeways 10-K for 2023). Shapeways then divested it again before its own bankruptcy in July 2024 (TCT). As of October 2026, the mfg.com site returns an error to automated fetches and we could not identify the current owner. An RFQ marketplace that outlived two owners and a dot-com cycle, and still ended up as a $3 million line item.

If what you actually need is a list of US job shops to send an RFQ to, EveryJobShop is an index of CNC, sheet metal and welding shops with request-for-quote, built by the same company as Next Everything.

3D Hubs, then Hubs, then Protolabs Network

3D Hubs started in Amsterdam in 2013 (Bram de Zwart, Brian Garret, Filemon Schöffer) as a map of local 3D printers you could order from. It grew into a B2B marketplace for 3D printing, CNC, injection molding and sheet metal (Wikipedia).

Protolabs acquired it in January 2021 for $280 million plus up to $50 million in earnout (Wikipedia: Protolabs). The name changed to Hubs in 2021 and to Protolabs Network in January 2024, and the service is still served at hubs.com with more than 250 manufacturing partners.

This one is a success by the measure that matters to founders and investors: a large exit. For buyers, Trustpilot reviewers (4.1 out of 5, 891 reviews) still mention the split between the Protolabs and Network sites and apps (Trustpilot). Two business models under one roof is not automatically one product.

Shapeways

Shapeways was spun out of Philips in Eindhoven in 2007 and became the best-known consumer and prosumer 3D printing service, with 55 or more materials and 8 processes as of 2025 (Wikipedia). As a public company it bought MFG.com (above).

On July 2, 2024, it filed for Chapter 7, ceased operations and was delisted from the NYSE. The OTTO and MFG.com units had been sold before the filing. The Dutch operation was restarted on August 1, 2024 by Manuevo BV, a vehicle of co-founders Marleen Vogelaar and Robert Schouwenburg together with the Eindhoven management team. The US brand and IP were bought in November and December 2024, and Shapeways relaunched from Eindhoven on December 3, 2024 (3D Printing Industry, TCT, Shapeways FAQ). It had 88 employees in 2025 and acquired the Thangs model platform from Physna on December 18, 2024 (Wikipedia).

So Shapeways is both on the graveyard list and off it: the public company is gone, the brand and the Eindhoven operation are running again, smaller and private.

Fictiv

Fictiv was founded in 2013 by Dave and Nate Evans in the Bay Area. It calls itself a manufacturing-as-a-service portal: CNC, sheet metal, injection molding, die casting, 3D printing and urethane casting, with plants in the US, India, Mexico and China, and more than 35 million parts produced (Fictiv, TCT).

On April 17, 2025, MISUMI Group announced it would acquire Fictiv for $350 million in cash through MISUMI Investment USA; TCT reported completion on June 16, 2025. Fictiv continues to operate under its own brand (MISUMI press release, TCT).

This is the most interesting exit on the list, because the buyer is not another marketplace. MISUMI is a catalog of configurable standard parts. We wrote a separate post on what the Fictiv and MISUMI deal means.

The survivors: Xometry

Xometry was founded in 2013 as NextLine Manufacturing and renamed in 2015. It listed on Nasdaq on June 29, 2021, and reports more than 4,200 active suppliers and 78,000 buyers (Wikipedia). Along the way it bought MakeTime (2018), Machine Tool & Supply (2019), Shift, which became Xometry Europe (2019), and Thomas for about $300 million (2021).

What it did that the dead marketplaces did not: it stayed a marketplace rather than building plants, it bought demand (Thomas) as well as supply (MakeTime), and it kept investing in the quoting engine. In 2026 alone it announced a lead-time prediction model for enterprise machining, a new cost-prediction model, and a partnership to embed Xometry quoting inside Siemens Xcelerator (Q1 2026 call transcript, Q2 2026 highlights). A new CEO, Sanjeev Singh Sahni, took over in July 2026 with founder Randy Altschuler as Executive Chairman (Wikipedia). Our head-to-head is in Next Everything vs Xometry.

The survivors: Protolabs

Protolabs is the oldest survivor, founded in 1999 as Protomold by Larry Lukis in Maple Plain, Minnesota. It owns its factories for injection molding, CNC, 3D printing and sheet metal, and since 2021 it also owns the marketplace (Protolabs Network). Revenue was $501 million in 2024 (Wikipedia). In February 2026 it launched ProDesk, which it describes as AI-driven DFM analysis and real-time quoting across its processes (3D ADEPT).

Protolabs shows that owning factories is survivable, with two conditions: you were an established manufacturer long before the venture wave, and you bought a marketplace for the long tail rather than building more plants.

The survivors: JLCPCB and the JLC group

The third survivor came from a different direction. JLCPCB, founded in 2006 in Shenzhen, is a PCB fab and assembler whose sister brands cover design (EasyEDA), components (LCSC), 3D printing (JLC3DP), CNC (JLCCNC) and mechanical parts (JLCMC). The group reported more than 9.5 million customers and 21 million orders a year as of December 2025 (JLCPCB).

Two things stand out. First, it is a factory business that won on volume and price at the small end, the segment the venture-backed marketplaces mostly ignored. Second, it has a public API, JLCAPI, covering PCB quoting and ordering, stencils, 3D printing and components (api.jlcpcb.com), which is why community MCP servers for JLCPCB exist today while most incumbents have none. More on that below.

The patterns

Eight stories, four recurring reasons.

Factories eat the capital. Plethora and Voodoo owned the machines. Fast Radius and Shapeways were manufacturers in their own right, not brokers. Every one of the four closed or went bankrupt. MakeTime, MFG.com and 3D Hubs were networks of other people's shops, and every one of them was bought instead. Fictiv sits in between, with its own plants in four countries, and was bought by a company with far deeper pockets. The marketplaces died gently; the manufacturers died hard. Protolabs is the exception that proves the point: it was a factory for two decades first and bought its marketplace later.

Take rates are not published, and the math is tight. None of the surviving marketplaces publishes a take rate; we could not find one for Xometry (Xometry). What the public sampling does show is that pricing between Xometry and Protolabs flips from quarter to quarter, cheaper in one, pricier in the next (Industrial Analyst). When two large players are that close, the margin for a smaller entrant to pay for growth is thin.

Customer acquisition is the real factory. An engineer buys a prototype a few times a year. Every marketplace on this list had to find that engineer again and again, at the moment of need, bidding against the same competitors. Xometry's answer was to buy Thomas, a supplier directory with decades of inbound traffic. Nobody on the graveyard list had that.

One process per platform, and the buyer does the integration. Voodoo was FDM. Plethora was CNC. 3D Hubs started with 3D printing. The platforms expanded processes slowly, and almost none of them touched electronics at all. A hardware project needs a PCB, the components on it, a printed enclosure and a machined bracket. In 2026 that is still four tabs, four accounts, four checkouts and four tracking numbers, and the engineer is the integration layer. The marketplaces competed on quote speed for one of the four tabs.

What the next one looks like

Here is the question the graveyard does not answer: who is the buyer now?

Increasingly, it is not a person on a website. It is an AI agent inside an editor, reading a KiCad project, a CadQuery script or a BOM, and asking a tool for prices. The protocol that lets it do that, MCP, is explained in MCP in five minutes. If the buyer is an agent, the marketplace is no longer a web page with a quote button. It is a set of tools: scan the project, search parts, quote, check out with a human in the loop, track.

As of October 14, 2026, none of the incumbents offers that. We found no official MCP server or agent-ordering flow from Xometry, Protolabs, Fictiv, DigiKey, Mouser, Octopart, PCBWay or MISUMI. One secondary article claims Xometry has developer docs with an llms.txt index, but the developer domain did not resolve when we checked, so treat that as unverified (Referently). The same article says Autodesk Fusion shipped official MCP support in May 2026, which would put an agent inside the CAD tool itself.

What does exist is small, new and mostly single-process, which should sound familiar:

• Make Parts Now (Las Vegas, US-only): MCP and REST with 18 tools, from create_agent_account and upload_part to create_quote, create_checkout_link and get_order; SLS, FDM and CNC in aluminum and brass. First observed October 6, 2026 (makepartsnow.com, Glama).
• Agentic Fabrication Network: ranked multi-vendor quotes for FDM, CNC, sheet metal, laser and decals; create_checkout returns a payment link and places the vendor order after payment. Scored September 9, 2026 (Glama).
• AIURION Agentic 3D Printing (San Francisco): 7 tools with guest sessions, quotes, Stripe checkout and order status. First observed August 14, 2026 (Glama).
• 3D Printer on Demand (US): 9 quoting and DFM tools, ordering finished on the website. First observed October 11, 2026 (Glama).
• Hands for Agents (Prague): human-in-the-loop physical tasks including FDM and CNC via subcontractors; opened September 2026, no tasks completed at the time of listing (Glama).
• FabTally: FDM slicing, quoting and DFM over MCP, paid per call in USDC; no order tool (Glama).

On the electronics side, JLCPCB has the official JLCAPI, an @jlcpcb/mcp package on npm (first published January 1, 2026, parts search and KiCad library install, no ordering, affiliation unverified) and a community server, Eyalm321/jlcpcb-mcp, with 28 tools including real, opt-in order creation (npm, Glama). DigiKey and Mouser have REST APIs and community wrappers only (DigiKey developer portal, pcbparts-mcp).

Notice the shape of this list. Almost every entry is one process, one region, one checkout. The agent still calls four services to build one device, so the engineer still owns the integration, now by proxy. It is the 2015 marketplace map with a new buyer.

What Next Everything is trying

Next Everything is a bet on the other shape: one quote for the whole project, prepared by your agent, approved by you.

The product is an MCP server at https://mcp.nexteverything.io/mcp that your assistant (Claude, Claude Code, Cursor, Codex, VS Code and others) connects to with a personal key. The tools map to the four tabs above: nx_scan_project extracts a normalized BOM from a repository or folder and resolves each line to an orderable part; nx_search_parts returns live stock and prices by part number, spec or plain description, with alternates ranked by compatibility; nx_quote prices the full build, electronics, PCBs, 3D prints and CNC parts, including shipping and duties; nx_quote_fabrication quotes one STEP, STL, 3MF, DXF or Gerber package; nx_checkout creates a payment link that you open and confirm yourself; nx_track_order follows every sub-order in one view. The agent cannot pay. Quotes are valid 24 hours, prices are landed, and if a part is out of stock you get a clearly marked replacement, with nothing swapped without your OK. The service is free; you pay for the parts in an order you approve. Details are in the docs.

One quote across four processes is exactly what the companies above found hard. The difference this time is who does the integration work: not a sales team on each side, but the assistant that already knows the project, with the buyer approving every payment.

If you want to see the full list of options including the incumbents, start with Xometry alternatives. If you want to try the agent route, sign up, paste one snippet into your assistant, and ask it to price the parts for the thing you are building. You approve every order yourself.
