SLICED 3MF STEP / CAD Sliced 3MF or a STEP from CAD? You’re in the right place.

Export a sliced 3MF from Bambu Studio or OrcaSlicer, or a STEP straight from Fusion, SolidWorks, FreeCAD or Onshape, and we price it instantly, with a live 3D preview at true printed size. Multi-plate 3MF? We read every plate and you pick which to print. Most UK print services take STL only, they reject sliced 3MF and STEP outright, or bounce you to a manual quote form.

  • Sliced 3MF, priced from your slicer data
  • STEP from CAD, no STL export needed
  • 3D preview + multi-plate selection

Upload your file

An STL file is the standard format for 3D printing. If you downloaded a model from Thingiverse, Printables or MakerWorld, that’s the one. Need a model made from scratch? We work with CEEQ Design, a Basingstoke CAD and mechanical design firm, who can turn your idea or a broken part into a print-ready file. We print it once it’s done.

Minimum order £6. Every order is printed and checked by hand here in Basingstoke, then posted tracked. That floor covers UK time and care, not a mass overseas run. Smaller parts work out best ordered together: add one to your cart, then upload the next.

Your file stays with one person in Basingstoke. We use it only to print your order, quote files that are not ordered are wiped from the server within 30 days, and we never share or resell them.

On your phone? Send us the STL on WhatsApp and we’ll quote you back.

Is there a minimum order?

Our order minimum is just £6, and small prints start from £4. Many established UK print services set a minimum order of £15 to £40, so one-off parts and small jobs that other places turn away are welcome here. You get a firm price up front from the instant calculator, with no quote form and no minimum-order surprise at checkout.

What’s an STL file?

It’s the standard file format for 3D printing. If you’ve downloaded a model from sites like Thingiverse, Printables or MakerWorld, it’ll usually be an .stl file. Don’t have a model yet? If it’s a simple replacement part, send a photo (a ruler in shot helps) or rough dimensions through the contact page and we’ll tell you if we can get it modelled and printed for you. The modelling is done by CEEQ Design, a local Basingstoke CAD firm we partner with. They produce the file and we print it.

What if it arrives damaged?

Send us a photo and we will arrange a free replacement. You are dealing with one UK workshop, so there is always a real person to put it right.

Can you print branded or licensed parts?

We will not reproduce branded, trademarked or licensed parts without proof you hold the rights. Your own designs and freely licensed models are absolutely fine.

What about .3mf or multi-colour prints?

Sliced .3mf files get the same instant price as STLs, the slicer’s embedded grams and print time are what we use. In Bambu Studio or OrcaSlicer, slice your plates, then File → Export → Export plate sliced file (or Export all plate sliced files) and drop the result into the uploader. The price tool will show each plate with a thumbnail so you can tick just the ones you want printed; the colours in the file decide which filaments we load. Only project files that aren’t sliced yet fall back to a same-day manual quote.

Can you print a STEP file straight from CAD?

Yes. Drop your .step or .stp file into the uploader and it gets the same instant price as an STL, no need to export a mesh from Fusion 360, FreeCAD, SolidWorks or Onshape first. We convert the CAD solid to a print-ready mesh in-house, keeping your exact dimensions. If a particular STEP file won’t convert (it happens with some exports), send it via the contact page and we’ll quote it manually the same day.

What’s the difference between PLA and PETG?

PLA is the most popular 3D printing material, it produces clean prints with a nice finish, and it’s great for decorative items, prototypes and general-purpose parts. PETG is tougher and more resistant to heat and moisture, making it better for functional parts that need to withstand stress, outdoor use or higher temperatures.

What does “strength” mean?

3D printed parts aren’t solid all the way through, the inside has a pattern (called infill) that determines how strong the part is. Light is fine for display items and covers. Standard works for most everyday parts. Strong or above is for parts that will bear loads or take mechanical stress.

Will my print be perfectly smooth, or will I see layer lines?

FDM 3D printing builds parts up in fine layers, so a printed part has a subtle layered texture rather than the dead-smooth finish of an injection-moulded original, this is normal for the process, not a fault. For most functional and display parts it looks great straight off the printer. If you’re after a flawless, paint-ready or show finish, the part may need a little post-processing, light sanding, filler-primer and paint, which you can do yourself or we can quote as an add-on. Tell us what the part is for and we’ll recommend the best material and orientation for the cleanest result.

Is this the final price?

Yes, what you see is what you pay. No hidden fees, no surprise extras once you’ve paid. Shipping is priced separately at checkout (free second-class on orders over £40). If we spot a problem with the file after you’ve paid (bad mesh, unprintable geometry, anything else we can’t sensibly fix) we’ll email you and refund in full within 24 hours, no questions asked.

Why do engineering materials cost more?

PLA Basic and PETG are in stock, so they are the cheapest options. Engineering materials (PC, ABS, ASA, TPU, Nylon and the carbon-fibre composites PETG-CF and PA-CF) carry a higher per-gram rate, and a £40 minimum order, which covers buying in the specialist filament. Ordered-in materials add one working day to dispatch. It’s all shown in your price up front, and these materials come in a focused range of colours we can reliably source.

What does “No preference” colour mean?

It means we choose the filament colour for you from whatever we have in stock. To make good use of spare filament we sometimes print different parts of an order in different colours. This keeps your cost down and often speeds up dispatch, and it never affects the fit or print quality. If colour matters to you, pick a specific colour before ordering, as no-preference orders can’t be refunded or reprinted on colour grounds alone.

What does a print cost?

Upload an STL or sliced .3mf and the price tool gives you a firm price up-front, material, machine time and any PETG surcharge already included. That’s what you pay: order, pay through Stripe, we print. (Anything we can’t auto-price, we’ll quote manually the same day.)

Instant firm price Upload an STL or sliced .3mf and the price tool gives you the exact amount up-front, no quote-email ping-pong.
24-hour refund promise If we can’t print your file (bad mesh, unprintable geometry) we email you and refund in full within 24 hours.
Honest pricing What the price tool shows is what you pay. Free 2nd-class shipping on orders over £40.

Materials, from everyday PLA to carbon fibre

PLA and PETG stay on the shelf in a good range of colours. For most customer jobs the right pick is obvious once you know the difference:

PLA PETG
Best for Display pieces, props, decorative parts, prototypes Functional brackets, enclosures, replacement parts that have to take load
Strength Stiff but brittle, snaps under impact Tough & a bit flexible, shrugs off knocks
Heat resistance Softens around 55–60°C Holds shape to about 75–80°C
Outdoor / sunlight Not recommended, warps & goes brittle OK for short periods outside
Finish Matte, easy to sand & paint Slight sheen, glues well, harder to sand
Relative cost Standard Around 10–15% more

Need something tougher? ABS, ASA, TPU, PC, nylon and the carbon-fibre composites PETG-CF and PA-CF are all orderable straight from the price tool above; we buy the reel in for your job (+1 working day, £40 engineering minimum). We keep PLA and PETG on the shelf because 90% of jobs use one of them. Full detail in the materials guide and on the carbon fibre page.

How the 3D printing quote works

Drop an STL or a sliced .3mf onto the quoter and you get a firm price in about three seconds. No forms, no waiting for an email back, no surprise charges at the end. The price you see is the price you pay, and it covers the print itself in the material and colour you chose.

If you upload a raw STL we slice it on our side using sensible defaults for the material, wall count, infill and layer height tuned for a part that actually holds up. If you upload a sliced .3mf from Bambu Studio or OrcaSlicer we honour your settings, so power users stay in control of walls, infill pattern and supports.

What the price includes

The quote covers the printed part in your chosen material, everyday PLA through to PA-CF carbon fibre, single or multi-colour, plus basic support removal and a visual check before it goes in the post. Bulk runs of 5 or more identical parts get a discount that shows up automatically in the quote.

Lead time and delivery in the UK

Once you confirm and pay, the part goes into the print queue. Turnaround is typically 2 to 4 working days from order to dispatch, then Royal Mail or a tracked courier across the UK depending on size and weight. Small parts ship in a padded envelope; larger or fragile prints go in a box with foam.

When the quoter cannot give a price

A handful of files will not quote automatically, usually broken meshes, wildly oversized models, or geometry that needs custom support work. If that happens, send the file through contact and we will look at it by hand and come back with a price and a realistic timeline.
