I need a 3D printer that can read files directly from my local network via Wi-Fi.

Yes. What you want is LAN printing: the printer joins your Wi-Fi, and your computer sends the sliced print file directly across your home network rather than requiring a USB/SD card or internet/cloud service.

A few good fits:

• Bambu Lab P2S - $549.00 (West3D 3D Printing Supplies)

• Bambu Lab P1S Combo - $499.99 (Best Buy)

• Creality K1C - $379.99 (Best Buy)

• Prusa CORE One+ - $1,339.62 (Makerwiz)

• Bambu Lab P2S — supports LAN-only mode, so it can be controlled from devices on your local network without relying on Bambu's cloud. Bambu Studio can send print files over the LAN.BBL CDN+1

• Bambu Lab P1S — also supports Wi-Fi/LAN file transfer and is a less expensive option.Bambu Lab Community Forum

• Creality K1C — Wi-Fi-equipped CoreXY printer with network connectivity; a good option if you want to stay around the $350–400 range.

• Prusa CORE One+ — particularly attractive if by "local network" you mean a printer with a genuine local web interface. PrusaLink runs directly on the printer, lets you upload files and control prints over your LAN, and doesn't require internet access.Prusa Knowledge Base+1

One important distinction

If you specifically mean:

"I want to type the printer's local IP address into a browser, select a .gcode file from my NAS/PC, upload it, and start printing — with zero cloud dependency." I'd lean toward Prusa. PrusaLink is explicitly designed for this: it runs locally and supports file uploads and print control without internet access.Prusa Knowledge Base

If you mean:

"I want to slice on my PC and click Print, with the file automatically sent over Wi-Fi." Then Bambu Lab is very convenient.

If you tell me your budget (e.g. <$300, <$500, <$1,000) and whether you need an enclosed printer, I can narrow this to 2–3 specific models.

If you want a 3D printer that can pull print files directly over your local Wi-Fi network (without walking an SD card/USB stick over), look for a printer with LAN/Wi-Fi file transfer, not just “Wi-Fi enabled.” Some Wi-Fi printers only use a vendor cloud app.goodprints3d.com

Good options:

My shortlist depending on what you mean by “read files directly from my local network”:

• I want a browser page on my LAN where I upload G-code: → Prusa with PrusaLink is one of the clearest fits.Prusa Knowledge Base
• I want the easiest “slice → click send → printer starts” workflow: → Bambu Lab or Flashforge-style ecosystems are designed around that workflow, though you should verify LAN-only behavior for the exact model.TechRadar
• I want no internet/cloud dependency at all: → Prioritize explicit “local network,” “LAN mode,” or “local web interface” support. PrusaLink and some QIDI workflows specifically document local access.Prusa Knowledge Base+1

A few questions would narrow it down:

1. Do you want FDM filament printing or resin (SLA/MSLA)?
2. What is your budget (e.g., under $300, $500, $1000+)?
3. Do you need the printer to work on a network with no internet access, or is local Wi-Fi access enough?

Several modern 3D printers natively support sending files over a local Wi-Fi network (LAN-only mode) without needing to route your data through external cloud servers.

Top options that excel at local network, Wi-Fi-based file transfers include:

---

Bambu Lab Series (X1, P1, and A1 series)Bambu printers feature a dedicated LAN Only mode in their settings. Once enabled, you can send sliced print files directly from Bambu Studio over your local Wi-Fi network without the printer touching the internet.

---

DIY / Klipper Conversions (Voron, Ender upgrades with Sonic Pad / Pi)If you want absolute control over your local network, running a printer on Klipper firmware with Mainsail or Fluidd via a Raspberry Pi gives you a pure local web interface to drag-and-drop or upload .gcode files instantly over Wi-Fi.[1][2][3]

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

• What is your budget?
• Do you prefer an enclosed printer (for ABS/ASA/Nylon) or an open-frame bed slinger (for PLA/PETG)?
• Do you want multi-color capability?

Yes. The key distinction is that you want LAN/local-network file transfer, not merely a printer that has Wi-Fi and requires a cloud service.

Good options

• Bambu Lab P2S - $749.00 (West3D 3D Printing Supplies)

• Prusa CORE One+ - $1,199.00 (Ultimate 3D Printing Store)

• Bambu Lab A1 - $399.99 (Best Buy)

• Bambu Lab P2S Combo - $749.99 (Micro Center)

• Prusa CORE One+ — particularly good if local-only operation is important. It has Wi-Fi/Ethernet and PrusaLink, which lets you upload files and control the printer directly through its IP address on your LAN, without Internet access.Prusa Knowledge Base+1

• Bambu Lab P2S — a newer, fast enclosed option. Bambu printers have Wi-Fi connectivity and PC software for sending jobs, although Bambu's networking model is more integrated with its ecosystem than PrusaLink's straightforward local-web-interface approach.Bambulab

• Bambu Lab A1 — inexpensive option if you don't need an enclosure. It's a 256 × 256 × 256 mm printer with Wi-Fi and PC/app control.

• QIDI Q1 Pro/Q2 family — worth considering if you want an open Klipper-style system. The Q1 Pro, for example, could be addressed by IP on the LAN and files could be sent from QIDI Slicer; QIDI has since discontinued the Q1 Pro in favor of the Q2.QIDI Technology+1

If you mean something very specific

If by "read files directly from my local network" you mean:

I have a NAS/Windows/Linux file share containing .gcode/.3mf files, and I want the printer itself to browse that network share and print a file without uploading it through a cloud service. That's a different requirement, and considerably fewer printers support it natively.

If that's what you mean, tell me what your network storage is (Synology/NAS, Windows SMB share, Linux/NFS, etc.) and your budget, and I can narrow it down to printers that actually support that workflow.

Several modern 3D printers natively support reading, uploading, and printing files directly over your local network via Wi-Fi without relying on external cloud servers.

• Prusa Printers (MK4, MK4S, CORE One) — These feature PrusaLink , a local web server built directly into the printer's firmware. Over Wi-Fi, you can access the printer's dashboard via its local IP address or manage it through Prusa Connect to upload and start print files completely within your local network.help.prusa3d.com+1
• Klipper-Based Printers (Creality K1 Series, QIDI Tech , Voron builds) — These run powerful local web interfaces like Mainsail or Fluidd over Wi-Fi. You can type the printer's local IP address into any browser 3dprintingspace.com to drag-and-drop G-code files or send prints straight from compatible slicers completely offline.
• Bambu Lab Printers (X1, P1, and A1 Series) — While heavily cloud-reliant out of the box, they feature a built-in LAN Only Mode . Activating this disconnects the device from external servers while retaining local Wi-Fi functionality, allowing direct file transmission via Bambu Studio on your home network.reddit.com+1

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

• What is your budget range?
• Do you prefer a closed enclosure or an open-frame bed slinger?
• Are you comfortable with Klipper tinkering , or do you want an appliance-like experience?

Yes. The key feature you want is LAN/Wi-Fi printing—being able to send a sliced G-code file from a computer on your home network directly to the printer, without needing an SD card or USB stick.

• Bambu Lab P1S — excellent value. It's enclosed, fast, and has the same general Bambu LAN workflow. The current market price can make it particularly attractive if you don't need the newer P2S features.

• Bambu Lab A1 — budget choice. If you're mostly printing PLA/PETG and don't need an enclosure, this is a very capable inexpensive option.

One important distinction

If by "read files directly from my local network" you mean something more specific like:

Printer → browse a Windows/NAS network share → select an STL/G-code file → print it that's different from ordinary Wi-Fi printing.

Most modern printers don't directly mount an SMB/NFS network share. Instead, your PC runs the slicer, and you send the resulting G-code to the printer over LAN. Prusa's implementation is particularly clean for a local-only setup: PrusaLink provides a web interface on the printer's local IP and supports file uploads/printing without internet access.Prusa Knowledge Base

If you tell me your budget (e.g. <$300, $500, $1,000) and whether you need an enclosed printer, I can narrow this to 2–3 models that specifically support local-network printing without cloud dependence.

Several modern 3D printers feature built-in Wi-Fi and native local network (LAN-only or direct IP) file transfer capabilities without forcing you to use external cloud servers.

Top 3D Printers with Local Network Wi-Fi Support

Offers a dedicated LAN Only Mode in the printer settings. When enabled, your printer disconnects from the cloud completely, and you can send sliced files directly via Wi-Fi from Bambu Studio on your local network.

Features onboard Wi-Fi (via an included or optional ESP module) and fully supports Prusa Connect LAN mode or direct local network printing without requiring internet cloud connectivity.

Many modern Creality printers run Klipper firmware out of the box, exposing a local web interface (Fluidd/Mainsail) via your local Wi-Fi network where you can drag and drop G-code files directly.[1][2]

Comparison of Local Wi-Fi Printing Options

If you have a preferred budget range or print size , let me know and I can narrow down the exact model that fits your workspace.

Yes. If by “read files directly from my local network” you mean slice a model on your PC, then send the G-code over Wi-Fi to the printer without using a USB stick or necessarily sending it through the cloud, there are several good choices.

My top picks

• Bambu Lab P2S - $549.00 (B&H Photo)

Bambu Lab P2S — best overall for ease of use. It supports Wi-Fi printing and is a current enclosed printer. Bambu's LAN-only functionality allows devices on your local network to communicate with the printer without relying on a cloud connection.Bambulab

• Original Prusa MK4S - $799.00 (West3D 3D Printing Supplies)

Prusa MK4S — best if you specifically want a true local-network workflow. PrusaLink is built into the MK4S; you can open the printer's IP address from a computer on your LAN, upload files, monitor it, and control prints without Internet access.Prusa Knowledge Base+1

• Bambu Lab P1S Combo - $549.99 (Micro Center)

Bambu Lab P1S — excellent value. It has Wi-Fi connectivity and supports sending sliced files over the LAN from Bambu Studio.Bambulab+1

If “local network” is a hard requirement

I'd lean toward the Prusa MK4S. Its PrusaLink interface is explicitly designed to operate locally: you access the printer using its local IP address, upload files, and control the printer without Internet access.Prusa Knowledge Base

If you want maximum convenience and speed, I'd choose the Bambu P2S and use its LAN-only mode.

One important distinction: if you mean “the printer should browse a shared folder/NAS on my network and pull .gcode files from it by itself”, that's a somewhat different requirement. Most Wi-Fi printers don't behave like a network drive; instead, your slicer or a web interface pushes the file to the printer.

If you tell me your budget (e.g. <$300, $500, $1,000) and whether you need enclosed printing / multi-color / ABS or ASA, I can narrow it to 2–3 models.
