Getting Started
Where can I get something 3D printed in the UK?
3DColorPop is a UK-based FDM 3D printing service that prints custom parts from your files. Upload your STL, OBJ, STEP, or 3MF file at colorpop.company/instant-quote, receive a quote, and have your parts delivered in 2-5 business days. We ship throughout the UK and internationally with no minimum order.
Do I need a CAD file to get something 3D printed?
Ideally yes — we print from 3D files (STL, OBJ, STEP, 3MF). If you only have a sketch, photo, or rough idea, contact us. We offer a design service and can turn 2D drawings into printable 3D files. For simple parts like brackets or housings, this is a straightforward process.
What is FDM 3D printing, and how does it differ from SLA or SLS?
FDM (Fused Deposition Modeling) melts plastic filament and builds parts layer by layer. It's the most cost-effective technology and best for functional parts, prototypes, and production runs. SLA uses UV-cured resin and produces smoother surfaces but parts are more brittle and expensive. SLS (powder sintering) is more powerful but significantly more expensive. FDM is the right choice for most practical applications — durable parts, multiple material options, and the best price-to-quality ratio.
Can you 3D print replacement parts for appliances or machines?
Yes. This is one of our most common requests. If you have the measurements or a broken part to reference, we can produce a replacement in PLA+, PETG, or TPU depending on the application. Bring the part to a local library or maker space to scan it, or send us drawings with dimensions and we'll create the file.
Do you have a minimum order quantity?
No minimum order — ever. You can order a single part. This makes us popular for prototyping single designs before committing to larger runs, or for replacing one broken component.
Materials & Properties
What is the difference between PLA, PLA+, PETG, and TPU for 3D printing?
PLA+ is the most popular: easy to print, 15+ colours, best detail, but not suitable outdoors (softens above 60°C). PETG is tougher — chemical-resistant, UV-stable, food-safe, and handles up to 80°C, making it ideal for outdoor parts, food containers, and mechanical components. TPU is flexible and rubber-like — perfect for phone cases, gaskets, seals, and grips. For most indoor prototypes and models, choose PLA+. For anything functional, outdoor, or food-related, choose PETG. For flexible parts, choose TPU.
How strong are FDM 3D printed parts compared to injection moulded plastic?
FDM parts are generally 80-90% as strong as injection moulded parts in the direction parallel to layers, but weaker perpendicular to layers (the Z-axis). For most functional applications this is perfectly adequate. PETG and PLA+ parts handle everyday mechanical loads well. For high-stress applications, we recommend PETG or carbon-fibre reinforced filaments. Orientation during printing has a big impact on strength — we optimise this in our free file review.
Can 3D printed parts be used outdoors?
Yes, but material choice matters. PETG is UV-stable and weather-resistant — the go-to for outdoor use. TPU is also outdoor-safe and flexible. Standard PLA+ is not recommended for outdoor use as it yellows under UV and softens in warm weather (above 55-60°C). If your parts will be exposed to sunlight or temperature extremes, choose PETG.
Are 3D printed parts food-safe?
PETG is FDA-approved for food contact and is our recommended food-safe material. We use it for cookie cutters, cake stamps, kitchen tools, and food-contact items. PLA+ can technically be considered food-safe but has microscopic layer lines that can harbour bacteria — for anything that will be washed repeatedly or used with food regularly, PETG is safer. We have a dedicated bakery service with express 1-2 day delivery for food industry orders.
Can you 3D print in multiple colours?
Our standard service prints single-colour parts. We can print the same design in multiple colours as separate pieces for assembly. For multi-colour single parts, contact us to discuss options — some designs can be achieved with careful colour changes at specific layer heights.
What specialty materials do you offer beyond standard PLA and PETG?
We offer glow-in-the-dark filaments, wood-fill (has a real wood texture and can be sanded/stained), metal-fill (copper, brass, bronze — heavy and polishable), carbon-fibre reinforced PLA and PETG (lightweight and stiff), glass-fibre reinforced materials, and nylon. Carbon/glass/metal-fill materials require hardened steel nozzles which we have in-house.
Design & Technical
How accurate is FDM 3D printing? What tolerances can you achieve?
Typical accuracy is ±0.1mm for overall dimensions and ±0.05mm for hole diameters. Our standard 0.4mm nozzle prints at 0.2mm layer height giving excellent results for most applications. For tighter tolerances we use a 0.2mm nozzle at 0.1mm layer height. We verify dimensions with digital calipers before dispatch. If your project has critical tolerance requirements, mention them in your quote and we'll confirm achievability.
What is the maximum size you can 3D print?
Our build volume is 256×256×256mm per part. Parts larger than this can be printed in sections and assembled — this is common for architectural models, large enclosures, and props. Contact us if your part exceeds this size and we'll advise on the best split approach.
What design rules should I follow when designing for FDM printing?
Key rules: minimum wall thickness 1mm (0.8mm possible but fragile), maximum unsupported overhang 45° (anything steeper needs support material), minimum hole diameter 2mm for clean results, avoid large flat surfaces on the bed as they can warp (especially PETG). We offer a free design review with every order and will flag any issues before printing.
What post-processing and finishing options do you offer?
Standard: support removal and basic clean-up included with every order. Optional: light sanding to reduce layer lines on visible surfaces, primer coat for a smoother paint-ready finish. For specialist finishing like acetone vapour smoothing, painting, or metal plating, contact us to discuss requirements and pricing.
Can 3D printed parts be painted or glued?
Yes. PLA+ and PETG sand easily and accept acrylic or enamel paints well after a light sanding and primer coat. For gluing, super glue (cyanoacrylate) works well on PLA+. For PETG, plastic-compatible epoxy or solvent cement gives stronger bonds. TPU is harder to glue — contact adhesive or flexible epoxy is best. We can supply parts lightly sanded and primed on request.
Pricing & Ordering
How much does 3D printing cost in the UK?
Cost depends on size, material, and quantity. Small parts (e.g. a 50mm bracket) in PLA+ typically cost £3-8. Medium parts (100-150mm, moderate complexity) range from £8-25. Large parts or specialty materials cost more. You can get an exact price instantly by uploading your file at colorpop.company/instant-quote — no account required. Volume discounts apply automatically for multiple identical parts.
Do your prices include VAT?
Quotes from our instant quote system are shown excluding VAT. VAT at the standard UK rate (20%) is added at checkout for UK customers. Business customers can provide their VAT number for B2B invoicing. International orders outside the UK are VAT-exempt.
How do volume discounts work?
Volume discounts are automatically calculated in our quote system based on quantity. The more identical parts you order, the lower the per-part price — savings typically start from 10 units. You don't need to negotiate or ask; the discount is shown transparently before you confirm.
Is my design kept confidential?
Yes. We treat all uploaded files and designs as strictly confidential. We do not share, sell, or reproduce your designs. If you require a formal Non-Disclosure Agreement (NDA) for commercially sensitive projects, contact us and we'll arrange one before you share any files.
What payment methods do you accept?
We accept all major credit and debit cards (Visa, Mastercard, Amex), PayPal, and bank transfer (BACS) for larger orders. Payment is only required when you approve your quote and confirm the order. No payment is taken for quote requests.
Turnaround & Delivery
How long does 3D printing take in the UK?
Standard turnaround is 2-5 business days from order confirmation to dispatch. Express production takes 24-48 hours for an additional fee. Bakery orders (cookie cutters, stamps) ship in 1-2 days. Turnaround depends on complexity and quantity — we confirm exact timing with every order.
Can I get 3D printed parts with next-day delivery in the UK?
Yes, for many parts. Our express production completes in 24-48 hours, combined with next-day courier delivery means you can have parts in as little as 2 days from order. For simple parts ordered before noon, same-day dispatch is sometimes possible. Contact us to confirm if your deadline is tight.
Do you ship internationally?
Yes, we ship worldwide from the UK. International shipping times vary by destination — typically 3-7 days to Europe and 5-14 days to the rest of the world. International orders are VAT-exempt for non-UK customers. Tracking is provided for all international shipments.
How are parts packaged for shipping?
Parts are wrapped in protective foam or bubble wrap and packed in rigid boxes sized to prevent movement. Fragile or detailed parts receive extra padding. We've dispatched thousands of orders without damage issues, but if a part arrives damaged, we reprint and reship at no charge — just send us a photo within 48 hours of delivery.
About 3DColorPop
Why choose 3DColorPop over other UK 3D printing services?
Three main reasons: speed (2-5 day standard turnaround, 24-48 hour express), trust (7,000+ completed orders, 1,700+ five-star reviews), and no minimums (order 1 part or 1,000). We started on Etsy where customer satisfaction is everything, and we brought that same standard to our independent service. Free design review and a response within 2 hours sets us apart from slower, less personal services.
Are you a UK-based company?
Yes. We are fully UK-based, which means faster domestic delivery, GBP pricing with no currency conversion, UK VAT invoices for business customers, and a team you can actually contact and get a quick response from. We don't outsource printing overseas.
What industries do you work with?
We work across automotive and aerospace (brackets, prototypes, tooling), healthcare (device housings, training models), electronics (enclosures, PCB holders), architecture (scale models), education and research (teaching aids, prototypes), bakery and food (cookie cutters, stamps in food-safe materials), arts and entertainment (props, figures), and business (NFC cards, branded items). No industry is too niche — if it can be 3D printed, we can help.
Can you handle ongoing or repeat production orders?
Yes. We support ongoing supply relationships where you place regular batch orders. We store your approved files and settings so repeat orders are fast and consistent. Contact us to discuss a production agreement if you need regular quantities — we can offer improved lead times and pricing for committed volumes.
Is 3DColorPop suitable for businesses, or just individuals?
Both. Individuals use us for one-off prints, replacement parts, and hobby projects. Businesses use us for rapid prototyping, product development, small batch production, and ongoing supply. We provide VAT invoices, can sign NDAs, and offer B2B payment terms for established business accounts. We scale from a single prototype to production runs of 1,000+ units.
