Make Mechanical Parts with Flux

Flux is an AI hardware engineer. It prepares mechanical parts for manufacturing and helps you get quotes and place orders.

Prepare a part for manufacturing

Ask Flux to prepare the part for a manufacturing process. Name the process and the material.

Prepare this motor bracket for CNC machining in aluminum 6061.
Prepare this display bezel for SLA printing in black resin and export it as STL.
Prepare this flat battery tray for sheet metal and export its profile as DXF.

You can also do it step by step:

Start with the model and describe how you want to make the part. Flux supports 3D printing, CNC machining, sheet metal, laser cutting, injection molding, and casting. The right process depends on the part's shape, material, quantity, and product requirements.

  1. Select the part or assembly in the project.

  2. Tell Flux the intended process and material.

  3. Describe the dimensions, finish, and product requirements that matter.

  4. Ask Flux to prepare the model for that process.

  5. Export a model or drawing file for a quote.

3D printing processes include FDM, SLA/DLP, SLS, MJF, material and binder jetting, and metal powder-bed fusion. CNC machining works with machined parts. Sheet metal and laser cutting use flat-part geometry. Injection molding and casting support molded or cast parts.

Use plain material names in your requests. For example, ask for PA12 nylon, black resin, or aluminum 6061. Name the part and process with the material so the request is clear. A motor bracket may need a metal part. A display enclosure may need a printed prototype before you prepare the production design.

Make CNC toolpaths and G-code

Ask Flux to make the CNC toolpaths for a part. Flux makes the toolpaths on its cloud computer and gives you the G-code file and a toolpath preview.

Tell Flux the machine, the stock, the cutters, and how you hold the part. Flux then has all the data that it needs to make the toolpaths.

Make the CNC toolpaths for this 6061 aluminum bracket on my Haas VF-2. Stock is a 65 x 45 x 8 mm block in a 6 in vise on 4 mm parallels. Use a 6 mm and a 3 mm carbide flat end mill. Set work zero at the top-left corner of the stock top face. Give me the G-code file and a toolpath preview.
Design a 6061 aluminum mounting bracket, 60 x 40 x 6 mm, with four M4 through holes and a 20 mm center slot. Then make the toolpaths to mill it on my 3-axis mill and give me the G-code.
Make 3-axis toolpaths for the motor mount in this project. My mill has a Fanuc controller. Stock is a 100 x 60 x 12 mm 6061 block in a 6 in vise. Pick the cutters yourself and give me the G-code file.
Make the facing, drilling, and pocket toolpaths for this enclosure lid in 6061 aluminum. Use a 6 mm flat end mill and a 3 mm drill. Give me the G-code and the setup sheet.

Flux makes these files:

  • The G-code file (.nc) for your machine.

  • A toolpath preview that shows each operation, for example facing, holes, slot, and profile.

  • A setup document with the stock, the tools, the work zero, and the workholding.


To get the files in the UI:

  1. Open the thread where Flux made the toolpaths.

  2. Select the G-code file link in the reply of Flux to download the file.

  3. Select the toolpath preview to see it larger.

  4. Open the Files tab to read the setup document.

  5. Open the G-code file in your machine controller or in a G-code viewer.


Get a quote and order the part

Ask Flux to prepare a quote or order the selected offer.

Get 3D-print and CNC quotes for this bracket in PA12 nylon and aluminum 6061. Compare price and lead time.
Get a Craftcloud quote for this enclosure lid in PA12 nylon, then order the offer with the shortest lead time.

See Get quotes for 3D prints and CNC parts to compare offers, then order 3D prints and CNC parts from Craftcloud.

Match the file to the process

Ask Flux to export the file format that your vendor needs.

Export the printed bracket as STL and the machined housing as STEP.
Export the outline of the laser-cut cover as DXF.

Use a 3D model file for a part that needs its solid geometry. Use DXF or another drawing format for flat-part work. Prepare the output that matches the vendor's workflow.

  1. Choose STEP, STL, OBJ, 3MF, or BREP for the part model.

  2. Choose DXF or SVG for a flat outline or artwork.

  3. Include the material and process in the quote request.

  4. Keep the exported file with the design files for the product.

Flux can prepare model assets and drawing files from the project. A 3D-printed bracket may use an STL file. A machined housing may use STEP. A laser-cut cover may use a DXF outline. Name the file for the part and its purpose.
