3D printing guides
Practical answers to the questions people ask before ordering a print, from Layer & Loop Store — a UK FDM 3D printing service in Norfolk that prints customer-supplied STL and 3MF files. New to this? Start with how to get something 3D printed in the UK.
Getting something printed
How to get something 3D printed in the UK
A plain-English walkthrough of getting a part 3D printed in the UK without owning a printer: getting a model, uploading an STL or 3MF, choosing material, pricing, and UK delivery.
How to get an STL file printed if you don't own a 3D printer
Where to get an STL or 3MF file 3D printed in the UK without a printer: how Layer & Loop Store's upload, quote, print and dispatch process works, what to check first, and when it's the right fit.
How much does 3D printing cost in the UK?
What actually drives the price of a 3D print in the UK — material, machine time, supports, quality, quantity and delivery — why two parts of the same weight can cost differently, and how an instant quote prices your model.
How to choose a 3D printing service in the UK
What to compare when choosing a UK 3D printing service — file types, printing process, materials, quoting, quantities, design help and delivery — and which jobs suit an FDM service like Layer & Loop Store.
Can I get a replacement plastic part 3D printed?
When a broken or discontinued plastic part can be replaced with a 3D print, where the printable model comes from, which parts are and aren't suitable, and how to order one in the UK from Layer & Loop Store.
Files, design and print settings
STL vs 3MF: which file should I use for 3D printing?
A practical comparison of the STL and 3MF 3D-printing file formats — what each stores, when to use which, and how to set up a multicolour 3MF so it prints the way you intended.
How to prepare an STL for 3D printing
A checklist for getting an STL or 3MF ready for a 3D printing service: correct size and units, watertight geometry, wall thickness, small features, holes and clearances, and what to put in your order notes.
Why did a detail disappear when my model was sliced?
Why thin walls, small text and fine features can vanish or soften between a CAD model and an FDM print — nozzle width, layer height and minimum feature size — and how to design or order so they survive.
Why do 3D printed holes come out too small?
Why holes, bores and slots in FDM prints usually come out slightly undersized, how much clearance to design in for bolts, shafts and mating parts, and when a test print is worth it.
Does print orientation matter, and will my part need supports?
How the way a part sits on the print bed changes its strength, surface finish and support needs, what support marks look like, and how to tell a 3D printing service which faces matter.
Which print quality and layer height should I choose?
What layer height, infill and nozzle size actually change on an FDM print, why a lower layer height isn't automatically better, and how to pick between Draft, Standard and Strong on a Layer & Loop Store quote.
Can a model bigger than the printer be 3D printed in pieces?
How models larger than a printer's build volume are split into sections, where to put the joins, how to keep pieces aligned, and what to send a 3D printing service for a multi-part print.
Production and manufacturing
Where can I get a prototype 3D printed in the UK?
How to get an FDM prototype printed in the UK from your own STL or 3MF, what to test on each revision — fit, holes, clearances, walls — and when to move from prototype to a production run.
3D printing one part vs production quantities
When an instant one-off order is the right choice and when a production run makes more sense — cost per part, consistency, lead time and repeat orders.
Can 3D printing be used for small-batch manufacturing?
Where FDM 3D printing works well for small-batch and low-volume manufacturing in the UK — good use cases, what changes at 10, 50 and 100+ parts, the trade-offs versus injection moulding, and how repeat production works.
3D printing vs injection moulding for low-volume production
How FDM 3D printing and injection moulding compare for a low-volume part: tooling versus per-part cost, why there is no universal crossover quantity, design changes, finish, tolerances and materials.
How do 3D printing production samples and sign-off work?
What a production sample is for, what to check on it — fit, dimensions, finish, orientation, support marks, assembly — and how an approved sample becomes the specification repeat orders are made to.
3D printed jigs, fixtures and production aids
Where FDM 3D printed jigs and fixtures work — assembly, alignment, drilling guides, inspection and workholding — and how to design them for strength, wear and repeatable positioning, with the limits to know.
