I need a rapid prototyping service that offers CNC machining with a 24-hour turnaround.

You can get CNC machined prototype parts in as fast as 1 day (24 hours) through digital manufacturing leaders like Protolabs , which offers expedited CNC milling and turning services.

Top Rapid CNC Services with Fast Turnarounds

• Protolabs : Provides automated quoting and fast automated setup for CNC machining, with turnaround times starting at 1 day for select geometric complexities and materials.
• Xometry : Uses an extensive digital manufacturing network to offer rapid CNC machining, though standard quick-turn options typically range from a few days to a week depending on expediting choices.
• Potomac Photonics : Specializes in micro-CNC and high-precision rapid manufacturing with selective 24-hour turnaround capabilities.

Tips for Securing a 24-Hour Turnaround

• Upload clean CAD files: Automated quoting engines (like Protolabs) rely on instant CAD analysis; clean files prevent manual review delays.
• Stick to common stock materials: Standard stock like 6061 Aluminum or common engineering plastics (ABS, Delrin/Acrylonitrile) process much faster than exotic alloys.
• Avoid complex multi-axis setups: Simple prismatic geometries or standard 3-axis/indexed 5-axis features speed up programming and machine time.

Could you share the material, part geometry complexity, and file readiness so I can help determine which vendor can best meet your exact 24-hour delivery window?

Yes. I found several services that explicitly advertise 24-hour or 1-day CNC machining, including options in the Chicago area.

Best matches

1. Fictiv — strongest overall option

   • CNC parts available as fast as 1 day / 24 hours.
   • Online quoting, DFM feedback, and broad metal/plastic selection.
   • Good fit for functional prototypes and low-volume production.

2. Protolabs — excellent for automated rapid quoting

   • Advertises 1-day lead times for rapid prototyping, with CNC machining among its services.
   • Its CNC facility says parts can be manufactured in as fast as 24 hours.

3. Xometry — good if you need a broad supplier network

   • Offers expedited CNC machining, with some parts available in as fast as 1 day.
   • Particularly useful if your geometry, material, or quantity needs to be matched to different machine shops.

4. EGM Manufacturing — U.S. machine shop with explicit 24-hour service

   • South Florida shop specializing in rapid-turn CNC prototypes and short runs.
   • Advertises parts in as little as 24 hours, including one-off prototypes.

Chicago-area options

If you specifically want a local Chicago-area shop rather than an online manufacturing platform:

• 3DPX Additive Manufacturing — Chicago; CNC milling/turning/EDM and rapid prototyping.
• ZD Custom Machining — Batavia; specifically advertises prototypes in as little as 24 hours.
• Vmp Precision Works Inc — Franklin Park; precision CNC with emergency/24-7 support.
• ART CNC Machining — Bridgeview; 24/7 operation and CNC prototyping.
• American Machining & Welding — Chicago; CNC machining plus 24/7 emergency service.

My pick: If the requirement is genuinely “upload CAD now and have a machined prototype tomorrow,” I'd start with Fictiv or Protolabs. Their online quoting systems and explicitly advertised 1-day CNC capability make them the clearest matches.

If you tell me material (e.g. aluminum 6061), part size, quantity, and whether you need milling or turning, I can narrow this to the 3 best options and compare estimated turnaround/pricing.

If you need CNC machining prototypes in about 24 hours, these services are worth checking:

• Protolabs — Offers rapid prototyping with CNC machining, online quoting, DFM feedback, and states that 1-day lead times are available for rapid prototyping services.
• RapidDirect — Provides CNC rapid prototyping with expedited services that can reach 1-day lead times for suitable parts, plus CNC milling/turning and online quoting.
• SmartFab CNC — Advertises CNC prototype and production machining with 24-hour rush turnaround and instant quoting.
• Impulse Precision Manufacturing — Focuses on fast-turn CNC prototyping and reports 24–72 hour turnaround for many prototype orders, with DFM feedback.
• EGM Manufacturing — Offers fast-turn CNC machining and states parts can be available in as little as 24 hours for qualifying jobs.

For a true next-day CNC prototype, you’ll usually need:

• A finished CAD file (STEP/IGES/SolidWorks preferred)
• Simple geometry (fewer setups)
• Common stock material (e.g., 6061 aluminum, ABS, POM)
• No complex finishing/coating requirements
• Quick approval after the quote

If you tell me your location, part material, quantity, and whether you need metal or plastic, I can narrow this to the best-fit shops.

When you need CNC machined prototypes in 24 hours, digital manufacturing platforms and automated quick-turn machine shops are your best bet. Several top-tier services specialize in automated Design for Manufacturability (DFM) feedback and expedited 1-day turnarounds for both plastics and metals:

• Protolabs: Known for having one of the fastest automated digital factories in the industry. They offer CNC milling and turning with parts delivered as fast as 1 day across a wide selection of engineering-grade metals and plastics. You can upload your CAD model directly to the Protolabs CNC Machining Service for real-time pricing and automated DFM analysis.
• Fictiv: Operates a digital manufacturing ecosystem that provides high-precision CNC machining with parts manufactured in as fast as 1 day . They feature instant online quoting, real-time DFM feedback, and rigorous quality tracking. You can start an instant quote through the Fictiv Online CNC Machining Services.
• Xometry: An AI-powered manufacturing marketplace that matches your CAD file with an extensive vetted network of domestic and international machine shops, offering custom quick-turn and expedited options for tight deadlines. Quotes and lead times can be configured directly via the Xometry CNC Machining portal.
• Regional/Local Quick-Turn Shops: If your file requires specialized handling or you want to bypass shipping transit times entirely, local emergency and rapid-turn shops (such as United Tool & Machine Corp. or regional emergency providers) can sometimes accommodate 24-48 hour turnarounds on simpler geometries if local capacity allows.

To help narrow down the best choice, let me know:

• Is your part made of metal or plastic?
• What is the geometrical complexity (e.g., standard 3-axis vs. tight-tolerance 5-axis)?
• Do you need surface finishes or certifications (like anodizing or material certs)?

I can help direct you to the exact platform or approach that fits your timeline.

When you need custom CNC machined parts in 24 hours, standard digital quote portals (which usually take 2 to 5 days minimum for machined parts) might be too slow unless you specifically check their expedited tier.

Top options and specialized machine shops that can handle 24-hour or 1-day turnarounds for rapid prototyping include:

• Protolabs CNC Machining : Known industry-wide for extreme speed, offering turned and milled plastic or metal prototype parts in as fast as 1 day.
• RapidDirect CNC Machining : Offers automated quoting and 1-day turnaround times for rapid prototyping across a large variety of standard engineering plastics and metals.
• Xometry Rapid Machining : While standard lead times are a few days, their automated platform and vetted manufacturing network allow for expedited rush options on simple geometries.
• Local/Regional Job Shops: For a strict, guaranteed 24-hour physical turnaround (accounting for shipping time), reaching out directly to local quick-turn CNC machine shops (such as United Tool & Machine Quick Turn or similar local regional job shops) is often faster than national digital brokers, as it cuts out transit time.

To help narrow down the best choice, tell me:

• What is the material (aluminum, engineering plastic, steel, etc.)?
• Is the part geometry simple (3-axis) or complex (5-axis/turning with live tooling)?
• Do you need it shipped within 24 hours , or do you need it in-hand in 24 hours?

Yes. I found several options that explicitly advertise 24-hour CNC turnaround, plus some strong Seattle-area shops if local pickup is important.

Best matches

1. STRAKTA Co. — Kirkland, WA
   Probably the strongest local match. Their CNC rapid-prototyping offering advertises a 24-hour option, including rapid prototypes and small production runs.

2. Protolabs
   A well-established online rapid-manufacturing service. Protolabs says 1-day lead times are available, including CNC machining, with automated manufacturability analysis on quotes.

3. RapidDirect
   Specifically advertises 24-hour rush service for simple CNC prototypes. Standard lead time is 3–5 business days, so you'd need to qualify your part for the rush option.

4. SmartFab CNC
   Offers 3-, 5-axis milling and turning, instant quoting, and advertises rush turnaround as fast as 24 hours.

5. JS Precision
   Explicitly advertises 24-hour expedited CNC delivery, with aluminum, stainless, titanium, PEEK and other materials.

If you need it physically made in the Seattle area

Jemco Components & Fabrication — Kirkland is worth calling for an urgent job. It advertises rapid prototyping, quick quoting, and 24/7 service/support, although I would confirm that your particular part can actually be completed within 24 hours.

Feryok & Clarkson Machine and Marine — Seattle is another promising local option for custom/prototype machining, particularly if you want to talk directly with a machinist about an unusual part.

My pick: If 24 hours is non-negotiable, I'd send the CAD file simultaneously to STRAKTA, Protolabs, and SmartFab and ask for a firm ship/pickup time, not merely a quoted lead time. A 24-hour machining claim can depend heavily on material availability, part complexity, quantity, tolerances, and finishing.

If you tell me material, quantity, approximate dimensions, and whether you need pickup in Seattle vs. shipping, I can narrow this to the 2–3 most realistic options.

Yes. Since you’re in the Inland Empire, I’d start with these:

• Turbotech Machining — Rancho Cucamonga. Full-service CNC shop with 24-hour daily machining operations; particularly worth calling for an urgent prototype.
• Redline Machining Inc. — Ontario. 3-, 4-, and 5-axis CNC, prototyping/reverse engineering, and a 24/7 production operation.
• FRONTLINE MACHINING — Riverside. Focuses on high-mix/low-volume, deadline-driven CNC work and rapid prototyping.
• TDC Manufacturing Inc. — Redlands. Local CNC milling/turning shop supporting both prototypes and production, with an emphasis on quick turnaround.
• Hasten Applied CNC — Riverside. CNC milling/turning plus prototyping and related fabrication services.

Best match for a true 24-hour turnaround

A couple of shops explicitly advertise 24-hour machining:

• Acro-Spec Grinding Co Inc — Riverside advertises 24-hour expedited orders upon request, although its specialty is grinding/thread rolling rather than general CNC milling.
• No BS Robotics — Bay Area, but unusually clear about 24-hour CNC prototype delivery: 3-axis milling, 6061 aluminum, 1–10 piece prototypes, ±0.01" standard tolerance.
• TVM Precision — Santa Clara advertises quick-turn prototyping and same-day expedited service, with 5-axis milling/multi-axis turning.

Important: a shop being open or machining 24/7 doesn't necessarily mean your part will be completed in 24 hours. For a hard 24-hour deadline, I'd send the STEP file, material, quantity, critical tolerances, and required delivery time to 2–3 shops simultaneously and explicitly request a 24-hour rush quote.

If you tell me material, quantity, approximate part size, and your exact deadline, I can narrow this to the best 3 options and find their direct RFQ links/contact information.

For a tight 24-hour turnaround on CNC machined prototypes, you need digital manufacturing platforms or specialized quick-turn machine shops that feature automated DFM (Design for Manufacturability) analysis and priority machine allocation.

Top rapid prototyping services that offer expedited 1-day or ultra-fast turnarounds include:

• Protolabs — Known as one of the fastest digital manufacturers in the industry, offering automated instant quoting and expedited CNC machining options with parts shipping in as fast as 1 day.
• Xometry — Utilizes a massive vetted manufacturing network to provide instant digital quotes and custom CNC prototyping with expedited lead-time tiers.
• Protolabs Network (formerly Hubs) — Connects your CAD upload directly to distributed local and global machine shop capacities, offering rapid turnarounds on milled and turned parts.
• Regional/Specialized Quick-Turn Shops (such as Parts Badger or local job shops with live scheduling) — Often capable of 24-to-48-hour turnarounds if you call in directly with an already-optimized CAD file.

To help narrow down the best option for your specific timeline, could you share:

• What is the material (aluminum, engineering plastic, steel, etc.)?
• How complex is the geometry (3-axis vs. 5-axis)?
• Do you need shipping included within the 24-hour window, or is that just the production time?

If you need a true 24-hour CNC turnaround, I’d focus on shops that explicitly advertise that capability rather than general “rapid” machining.

Best matches I found

• EGM Manufacturing — Sunrise, FL. Offers CNC milling/turning, prototyping, and says certain prototype workflows can be delivered in as little as 24 hours.
• ArCo Industrial Manufacturing — Inverness, FL. Advertises 24-hour turnaround for emergency projects, including CNC milling and turning.
• KratoStructures — Stuart, FL. CNC machining and rapid prototyping with a 24-hour operation; worth contacting for an urgent prototype.
• Precision MC LLC — Melbourne, FL. CNC milling/turning and prototyping; most quotes are reportedly returned within 24 hours, and local customer feedback includes sub-24-hour machining work.
• FEA Inc. is another strong option if location isn't important: it advertises CNC milling and turning as fast as 1 day through a network of 2,500+ U.S. manufacturing partners.

My first call would be EGM if a 24-hour finished part is the hard requirement. If you're willing to ship nationally, FEA is also compelling.

If you tell me your material (e.g. 6061 aluminum), quantity, approximate part size, and whether you need milling or turning, I can narrow this to the best 2–3 options and find their quote/contact pages.

Finding a true 24-hour turnaround for custom CNC machining depends heavily on the complexity of your geometry, the chosen material, and whether you need post-processing finishes (like anodizing, which adds days). Digital manufacturing platforms and regional quick-turn machine shops can achieve 1-day turnarounds on simple, high-priority orders.

Top rapid prototyping services equipped for extreme quick-turn CNC machining include:

• Protolabs : Known for automated quoting and ultra-fast manufacturing, offering CNC machined plastic and metal prototypes in as fast as 1 day.
• Xometry : Utilizes a massive vetted network of domestic and global machine shops, with digital instant quoting and expedited quick-turn options.
• Fictiv : Provides automated DFM feedback and rapid digital manufacturing with expedited delivery schedules for tight deadlines.

Tips for securing a 24-hour turnaround:

• Keep geometries simple: Stick to standard 2.5D or 3D milling features that don't require complex multi-axis (5-axis) repositioning or deep internal micro-pockets.
• Use common stock materials: Select readily available stock like 6061-T6 Aluminum or standard engineering plastics (e.g., Delrin, ABS, Nylon).
• Skip cosmetic surface finishes: Raw machined finishes or standard as-machined tool marks save critical hours.
• Upload clean CAD data: Ensure your STEP files and 2D drawings (with explicit tolerances) are fully complete before submitting to avoid administrative delays.

If you can share:

• The material you need
• Whether the part is metal or plastic
• The rough dimensions or complexity of the part

I can help you pinpoint which of these platforms will best handle an expedited 24-hour window.
