STEP File 3D Printing Australia | CAD to Part
3D Printing from STEP & CAD Files
Upload your STEP or STP file directly, no manual conversion needed, and get an instant online quote. Precision parts made to your CAD and drawing, dimension-checked before dispatch, delivered Australia-wide.
From CAD File to Finished Part
Most engineering parts start life as native CAD, not a mesh. Our quote tool accepts STEP and STP files directly: upload the same file your drawing references and our system converts it to a print-ready model automatically, keeps your original CAD on record, and prices the part instantly.
No exporting, no guessing at mesh settings, no emailing files back and forth. The part you see in the 3D preview is built from your exact CAD geometry, and both the original STEP and the converted model stay attached to your order for full traceability.
Why Upload STEP Files Directly
Skip the conversion step and keep your engineering intent intact.
Native CAD Accepted
Upload STEP or STP straight from SolidWorks, Fusion or FreeCAD.
Automatic Conversion
Server-side conversion to a print-ready model in seconds.
Original Kept
Your STEP file stays with the order for reference and reorders.
Instant Quotes
Geometry is priced online in seconds, no waiting for email.
Fewer Errors
No manual mesh exports means no broken or misscaled models.
Full Traceability
Drawing, CAD and printed part all reference the same file.
Parts Made to Drawing
If your part has a drawing, we work to it. Flag the critical dimensions and tolerances when you order and we orient and tune the print to protect them, just like the striker mount above, printed from its referenced STP file and verified against the drawing.
Typical accuracy is around plus or minus 0.3 mm depending on geometry and material. Where a dimension matters more than that, tell us, checking key features against your drawing before dispatch is part of the job.

What We Print from CAD
Brackets & Mounts
Structural parts made to hole patterns and datums.
Enclosures
Housings that fit boards and hardware first time.
Machine Parts
Replacement and upgrade components to spec.
Fixtures & Gauges
Tooling built from the same CAD as the workpiece.
Prototypes
Design iterations straight from your CAD revisions.
Production Runs
Repeat batches locked to a CAD revision.
Dimensional Accuracy & Inspection
3D printing is a real manufacturing process with real tolerances. As printed, expect around plus or minus 0.3 mm on most features, tighter on small parts, a little looser on large flat spans where thermal behaviour matters. Orientation, material and wall design all influence the result, which is why flagging critical features helps.
For parts with drawings we check key dimensions with calipers before dispatch. Holes can be printed slightly undersize and drilled or reamed to final size, and threads are best added with inserts or taps, tell us the fit you need and we will build the strategy into the print.
How It Works
Drop your STEP, STP or STL into the online quote tool.
STEP files convert automatically; the 3D preview confirms geometry.
Pick material and quantity, the price appears instantly.
We print, verify key dimensions and ship Australia-wide.
Who Prints from STEP With Us
Anyone who designs in real CAD and expects the part to match it.
Mechanical Engineers
Parts to drawing with protected critical dimensions.
Product Designers
Iterations printed straight from each CAD revision.
Maintenance Teams
Obsolete spares reproduced from measured CAD.
Machine Builders
Brackets, guards and guides to fit existing assemblies.
R&D Labs
Experimental hardware revised weekly from native CAD.
Manufacturers
Fixtures and end-use parts locked to a revision.
What to Send Us
- CAD file: STEP or STP uploaded directly; STL also accepted.
- Units & scale: millimetres, at real-world size.
- Drawing if you have one: PDF with critical dimensions flagged.
- Tolerance callouts: which features must be held, and to what.
- Mating parts: what the part bolts to or slides into, so fits can be protected.
- Quantity & cadence: one-off or repeat batches; revisions are tracked either way.
STEP File 3D Printing FAQs
Can I upload a STEP file directly for a quote?
Yes. The online quote tool accepts STEP and STP files, converts them automatically to a print-ready model and prices the part instantly. Your original CAD stays attached to the order.
Why print from STEP instead of STL?
STEP preserves your exact CAD geometry. Our conversion produces a fine, consistent mesh, so curved surfaces come out smoother and you avoid scale or unit mistakes from manual exports.
What tolerances can you hold?
Typically around plus or minus 0.3 mm depending on geometry, material and orientation. Flag critical dimensions and we will orient the print and check them before dispatch.
Do you work to engineering drawings?
Yes. Send the drawing with your order, note the critical features, and we will verify them with calipers before shipping, just like the parts on this page.
What CAD software do you support?
Any package that exports STEP or STP: SolidWorks, Fusion 360, Inventor, FreeCAD, Onshape, CATIA and more. The file format is universal.
Can I reorder the same part later?
Yes. Your CAD file and print settings are stored against the order, so a reorder months later matches the original run.
What about threads and precise holes?
Holes can print slightly undersize for drilling or reaming to final size, and threads are best handled with heat-set inserts or tapping. Tell us the fits you need and we will plan for them.
Is my CAD file kept confidential?
Yes. Files are stored securely in Australia, used only to make your parts, and never shared. We are happy to sign an NDA for sensitive work.
