3D Print on Demand: Connect with Verified Makers in Spain

Price depends on size, material, technology, quantity and finish. Indicative ranges for Mr Resin's custom 3D printing service in 2026: 28mm miniature in resin between €3 and €8, 75mm bust between €8 and €20, small FDM PLA enclosure between €5 and €12, 15cm decorative figure between €8 and €20, full cosplay helmet between €40 and €120, functional prototype between €15 and €80. Runs of 10 identical parts receive discounts of 20 to 40%, reducing the unit cost by 25 to 35%. Send your STL to Mr Resin and receive 2–4 real quotes within 5–10 business days (24–48h to mainland Spain).

The complete cycle from submitting your project to receiving the part at home is typically 5 to 10 business days. Typical breakdown with Mr Resin: 24-48h to receive 2-4 quotes from verified makers, 1 day to decide and accept, 2-4 days production for small parts (3-7 days medium, 7-14 days short runs), and 2-5 days shipping to mainland Spain (3-7 days to the Balearic and Canary Islands; allow additional time for international EU deliveries). If you select "Express" (under 3 days) for urgency, some makers accept with a 20-40% surcharge. If you select "No rush", you can get 5-15% discounts by filling gaps in the maker's print schedule. Flexibility on timeline is the easiest lever to reduce project costs.

The standard format is STL (stereolithography), supported by 100% of 3D printers on the market. OBJ, 3MF (Microsoft 3D Manufacturing Format) and STEP (for technical CAD) are also accepted. The file must be in real scale in millimetres and be a well-formed 3D file. Mr Resin's STL viewer automatically detects dimensions, volume in cm³ and estimated weight in grams based on the chosen material, processing everything in your browser without sending the file to any server. If your file has mesh errors, makers will repair it with prior notice (cost €5–20). If you don't have a 3D file, we also offer modelling from scratch (€30–200) or 3D scanning of an existing piece.

FDM (filament) is ideal for functional, large (up to 400×400×500mm), affordable and durable pieces: electronic enclosures, functional prototypes, cosplay, decoration, spare parts. Finish shows visible layers but can be sanded and painted. Price from €5/piece. SLA/LCD resin is better for pieces requiring sub-millimetre detail and a smooth surface: 28mm Warhammer or D&D miniatures, collector busts, jewellery, visual prototypes, dental pieces. Maximum size 218×123×260mm. Price from €3/piece individually. Quick rule: if it will be viewed up close and needs fine detail, go resin; if it needs to withstand mechanical stress or is large, go FDM. If unsure, select "I don't know" in the Mr Resin form and the team will recommend the optimal technology for your project.

Yes. In the Mr Resin form you can select "No, I need a design" and a 3D designer from the community will contact you. Typical process: 1) submit references (sketches, photos, measurements, inspirations); 2) 2–5 days of modelling with 2 included iterations; 3) delivery of the final STL and printing quote. Indicative design rates: simple functional piece €30–60, original miniature €80–150, complex project with assemblies €150–300, castable jewellery modelling €100–250. Alternative: 3D scanning of an existing physical piece with ~0.1mm precision for €50–150, ideal for replicating discontinued spare parts, collectibles or specific tools. You can combine design + printing in the same order with a bundle discount.

The most common FDM materials: PLA (€12.99/kg, decorative, max. 55 °C), PETG (€13.60/kg, functional up to 75 °C, basic outdoor use), ABS (€19.99/kg, mechanical and 85 °C), ASA (€16.99/kg, UV and rain resistant, 90 °C), flexible TPU (€24.99/kg, cases and gaskets), Nylon (technically resistant) and PLA-CF with carbon fibre (€21.99/kg, lightweight and rigid). For SLA/LCD resin: standard (€15.42/L, miniatures), ABS-like (€21.99/L, functional), flexible, high definition (€18–22/L) and castable for jewellery (€28–35/L). Mr Resin works with leading brands such as Anycubic and Elegoo, with direct stock and 24h shipping across Spain for those who prefer to print themselves.

A 28mm miniature (Warhammer 40k, Age of Sigmar, D&D, Frostgrave scale) printed in resin by Mr Resin's service costs between €3 and €8 per piece individually. Typical consumption is 3–6 ml of resin (€0.05–0.10 in material alone) and 15–25 minutes of post-processing (washing, UV curing, support removal). A 75mm bust costs between €8 and €20, a 32mm hero with decorated base between €5 and €12, a 40k vehicle miniature between €15 and €40. Batches of 10 identical miniatures get discounts of 20–40%, bringing the unit cost down to €2–5. If you add professional hand-painting, add €15–40 per miniature depending on the level of detail (standard, tournament or Golden Daemon level).

A functional FDM prototype costs between €15 and €80 depending on size and material: a 10 cm PETG enclosure is around €20–35, a mechanical part with metal inserts €40–70, a multi-part assembled device €60–150. A high-definition visual prototype in ABS-like resin costs between €20 and €100. Mr Resin works with companies, startups and freelancers/self-employed professionals who need to validate designs before investing in injection moulding or machining. For validation runs (5–20 units), discounts of 15–30% apply. Typical lead times: 3–7 days for a single prototype, 1–2 weeks for a validation run. Option to sign an NDA if your project is confidential or has a pending patent.

Yes, in four ways through Mr Resin's service. One: piece in a single base colour (the chosen filament or resin), from €0 extra. Two: multi-part piece assembled in different colours, +€5–15 per colour/piece change. Three: multi-colour printers allow several colours in a single print with a surcharge of 30–60%. Four: post-processing with professional painting, the most flexible option. Indicative painting rates: standard miniature €15–25, tournament miniature €30–60, bust €40–120, cosplay helmet €60–250, decorative piece €20–80. Includes priming, base coat, details, washes and final protective varnish in matte/satin/gloss.

It depends on the technology. With FDM, most home and semi-professional printers used by Mr Resin's makers reach 256×256×256mm and some go up to 400×400×500mm. With SLA/LCD resin, the current maximum is around 218×123×260mm (approximately 22×12×26 cm). For larger pieces (helmets, large statues, industrial prototypes) the model is split into parts that fit in the printer, printed in batches and assembled with filler and sanding. A full cosplay helmet is usually divided into 6–10 pieces; a 60cm statue into 15–25 pieces; a life-size prop replica into 30–80 pieces.

It depends entirely on the material. PLA degrades in sunlight (UV) and heat above 55 °C; not suitable for outdoor use or cars in summer. PETG withstands up to 75 °C, moisture and splashes: a good option for basic outdoor use (garden, covers, porch parts). ASA is the best FDM material for long-lasting outdoor use: UV resistant without yellowing, rain resistant, up to 90 °C and suitable for outdoor exposure for years. ABS resists impacts and heat (85 °C) but degrades under UV. Nylon and PLA-CF for technical parts under mechanical stress. Standard resin is NOT suitable for outdoor use or heat (it deforms above 50 °C and becomes brittle under UV). For outdoor functional parts, always use ASA or PETG. Indicate this in the "Use" field of the Mr Resin form so we can recommend the right material.

Three simple steps that complete a cycle of 5–10 days. One: you upload your STL file to the integrated 3D viewer, which extracts dimensions, volume and estimated weight in the browser without sending the file to any server, and you fill in the form with description, material, finishes, quantity, deadline and contact details. Two: Mr Resin reviews your request within hours and shares it with a curated group of verified makers in the @MrResin3D Telegram community, bringing together 5,000+ makers across Spain. Three: within 2–5 business days you receive 2–4 comparable quotes (price, lead time, exact material, finishes included), you choose your maker, pay directly, and receive your part at home with standard EU shipping (5–10 business days). Mr Resin acts as a trusted connector and dispute arbitrator; it does not print directly.

Yes. The Mr Resin community of 5,000+ makers includes a sub-group of verified professionals who meet requirements for a proven track record, professional equipment and the ability to issue proper invoices. Mr Resin filters each request and only shares the project with makers who can meet the requested deadline, budget and quality, reducing noise and improving the rate of successfully completed projects. The service is backed by 412 verified reviews on Judge.me with a rating of 4.92/5, accumulated since 2023 with more than 5,000 orders processed across Spain.

Yes. In the "Finishes and extras" section of the form you can select any combination of: support removal and cleaning (€2–4), manual sanding and polishing (€5–15), professional priming/primer (€3–8), hand or airbrush painting (€15–120) depending on complexity, matte/gloss/satin protective varnish (€3–8), assembly of multiple pieces (€5–20) and threaded metal inserts (€2–5 per insert). Mr Resin works with professional painters specialised by category: tournament miniatures (competition level), cosplay with realistic weathering, industrial prototypes with specific Pantone colour codes and architectural finishes. Each maker sends reference photos of previous work before accepting the commission to validate the expected standard.

Yes. Mr Resin's custom 3D printing service covers mainland Spain, the Balearic and Canary Islands, as well as Ceuta and Melilla.

Shipping is managed by the maker who accepts your project and varies by weight and destination. Indicative 2026 rates: standard mainland Spain 3.95–5.95 € (up to 2 kg), express 24h 9.95–14.95 €, Balearic Islands 7.95–12.95 €, Canary Islands 14.95–24.95 € (local IGIC tax of 7% and customs may apply), Ceuta/Melilla 14.95–24.95 €. For international EU orders, shipping typically ranges from 10–25 € depending on weight and destination. Bulky parts (cosplay helmets, sculptures, boxes over 30 cm) usually carry a volume surcharge of +5–15 €. Many Mr Resin makers offer free shipping from 50–80 € order value, especially for runs of identical parts. Every quote includes a transparent shipping cost breakdown so you know the full price before confirming — no surprises.

Yes, it is one of the specialities of Mr Resin's verified makers. Economies of scale applied: 1 unit = base price, 2–5 units = −10 to −20%, 6–20 units = −20 to −30%, 21–100 units = −30 to −40%, over 100 units = up to −50% (consult case by case). Common use cases: Wallapop and Etsy sellers (50–200 units/month), event and convention merchandising, personalised corporate gifts, education (anatomical models for classrooms), industrial tooling and production fixtures. Lead times: 10 units 3–5 days, 50 units 7–10 days, 100 units 10–15 days. For recurring volumes of 100+ units/month, Mr Resin refers to its B2B page /pages/empresas with specific terms and additional discounts.

Every verified maker on Mr Resin offers a conformity guarantee under EU consumer law (Directive 2019/771 and applicable national legislation): if the part arrives defective, poorly printed or does not match what was agreed in the quote, it will be reprinted at no cost or fully refunded within 14 days.The legal guarantee period is 3 years for individual consumers and 2 years for businesses. Mr Resin acts as intermediary and arbitrator in case of dispute, which adds a layer of trust compared to an anonymous marketplace. We recommend reviewing the quote in detail (material, finish, dimensions, tolerances) before accepting, and keeping the invoice and email correspondence in case any issue arises later.

Yes, your privacy is protected by design. Mr Resin's STL viewer processes your file 100% in your browser using JavaScript and Three.js; the STL is never sent to any external server or to Mr Resin's server. You can verify this by opening your browser's network tools (F12, Network tab) while uploading the file: you will not see any POST request containing the STL content. Only the extracted data is transmitted with the form (dimensions in mm, volume in cm³, estimated weight in grams and file name). If you later share the STL directly with the assigned maker, you can request a NDA (Non-Disclosure Agreement) beforehand; indicate this in "Additional notes". Ideal for industrial projects, pending patents and confidential designs.
