Why you need a professional quote tool
A handwritten quote sent over WhatsApp is the fastest way to lose jobs and argue with clients. A PDF with your logo, itemised breakdown and clear terms is the difference between looking like a hobbyist and looking like a business.
In 3D printing, 90% of makers who start selling on Wallapop, Etsy or social media price things «by eye». They calculate the price based on resin or filament volume, add a bit of margin and send it as a message: «Te sale 8€, te lo mando el viernes». That message is a disaster for three reasons:
- It doesn't include VAT. If the client pays you and the tax authority (e.g. HMRC in UK, IRS in US) comes asking, you absorb the 21%.
- It has no expiry date. If the client comes back 6 months later, you charge the same price even if resin has gone up 15%.
- It doesn't itemise anything. If a piece comes out defective, you can't justify where the cost lies or negotiate a replacement.
A professional PDF quote solves all three problems in 30 seconds. And if it also has your logo at the top, your client perceives you as a serious business, not a friend who prints things. Perceived professionalism = accepted margin.
Real data: makers who send PDF quotes achieve an average margin of ×3, compared to ×1.8 for those who send prices over WhatsApp. The same job, with the same cost, charged 66% more. The difference is perception.
The 5 mistakes that ruin 3D quotes
After speaking with hundreds of makers, the same mistakes keep coming up. If you make 3 or more of these, you're losing money on every job.
❌
1. Charging only for the material
A piece that uses €2 of resin actually costs you €5–7 once you factor in electricity, machine depreciation, LCD, FEP, alcohol and labour. If you charge €2 + margin, you are literally losing money.
🕓
2. Not including labour
Washing, curing, removing supports, sanding: that's 15–30 minutes per piece at €15/h. If you forget it, you're working for free. Always include labour as its own line item or within the unit cost.
💵
3. Forgetting VAT
If you invoice more than €1,000/year as a self-employed / freelancer / sole trader, 21% VAT (rates vary by country) is added on top. Charging «VAT included» without stating it means absorbing 17% of your margin.
📅
4. Not setting an expiry date
Resin and filament prices fluctuate 10–20% per year. A quote without «valid for 30 days» is an open-ended commitment at a fixed price forever.
📱
5. Sending a loose price over WhatsApp
No breakdown, no date, no logo. It looks like something from a hobbyist. The client haggles 30% off because «a WhatsApp message isn't official». A well-made PDF is what's official.
🔍
Bonus: not itemising extras
If you include painting, shipping or urgency inside the piece price, the client thinks it's expensive. If you list it as a separate line, they can see exactly why they're paying more.
What a professional 3D quote must include
These are the essential elements. The Mr Resin quote tool includes all of them by default.
| Element | Why it matters |
|---|---|
| Maker's logo | Brand perception. Without a logo, it's a Word document. With a logo, it's a business. |
| Tax ID / VAT number | Shows you are properly registered. Builds trust. |
| Client details | Personalises the quote. Avoids errors when sending. |
| Quote number | Traceability. If the client writes to you «the one from quote PR-20260416-003», you know exactly which one it is. |
| Issue date | Legally required if it is later converted into an invoice. |
| Validity | Protects you from material price changes. |
| Breakdown by piece | Description, technology, material, units, price. Full transparency. |
| Extras listed separately | Finishing, painting, shipping, urgency: each on its own line. |
| Subtotal + VAT 21% + Total | Calculated automatically. No addition errors. |
| Notes and conditions | Lead time, payment method, colour tolerances, included revisions. |
| Discreet footer | Mr Resin does not add intrusive branding. Just a thin line indicating the tool used. |
Important: a quote is not an invoice. When the client accepts and the work is completed, if you are self-employed or a business you must issue a separate invoice with an invoice number (different from the quote number). The quote tool generates quotes, not invoices.
How to connect the cost calculator with the quote tool
This is the key difference with Mr Resin: the calculators and the quote tool are integrated. The workflow has 3 steps.
Step 1 — Calculate the real cost of the piece
Open the resin cost calculator or the filament calculator. Select your material and printer, enter the volume or upload the STL. The calculator gives you the real itemised cost with the 6 components: material, electricity, depreciation, consumables, labour and failure buffer.
Step 2 — Send the piece to the quote tool
In the results panel, press the 📋 Send to quote tool button. The quote tool opens in a new tab with the piece pre-filled: description, technology (FDM or Resin), material, quantity and unit cost. A green toast appears confirming: «Pieza importada desde la calculadora ✓».
Step 3 — Adjust the margin and generate the PDF
All that remains is to adjust the margin per line (default 150%, ×2.5 semi-pro), add any extras if applicable, and press «Generate quote PDF». In 5 seconds you have the document ready with your logo and details.
Advantage: working with the real cost (not just the material cost) is what sets a profitable business apart from a hobbyist working at a loss. The quote tool requires you to start from the real cost, not from intuition.
VAT, self-employment and invoicing in 3D printing
A quick guide to what you need to know if you sell 3D printing services in 2026, or equivalent in your country. This is not tax advice: consult a professional for your specific situation.
When do I need to register?
The tax authority (e.g. HMRC in the UK, IRS in the US) considers any regular, profit-making activity an «economic activity». The indicative threshold is €1,000 per year or recurring monthly sales. If you sell every week on Wallapop, Etsy or Instagram, you are required to register as self-employed / sole trader and charge VAT.
What VAT rate do I apply?
The standard VAT rate is 21% in Spain (rates vary by country). 3D printing of decorative objects, miniatures, prototypes and functional parts is taxed at 21%. Service provisions (3D design, modelling, consultancy) are also at 21%. There is no reduced VAT rate for 3D printing in Spain.
How do I declare VAT?
Quarterly, using the quarterly VAT return (form varies by country) (April, July, October, January). Annually, submit an annual VAT summary return. If you invoice businesses in other EU countries, you will also need EU intra-community VAT registration.
Are a quote and an invoice the same thing?
No. A quote is an offer made before the work. An invoice is the document that creates the payment obligation and tax declaration. A quote accepted in writing is commercially binding, but it is not an invoice. When the client pays you, issue an invoice with its own numbering (different from the quote number).
Recommendation: if you are just starting out, use the Mr Resin quote tool to send professional offers. When your volume exceeds €3,000–5,000 per year, take the step to register as self-employed / sole trader and hire an accountant (€30–60/month) to handle your quarterly returns. The time you save can be spent printing.
Frequently asked questions
Yes, the Mr Resin 3D quote builder is 100% free and requires no registration. There is no premium version or usage limits. You can generate as many PDF quotes as you need with your own logo and company details. It is a tool developed by Mr Resin for the Spanish maker community.
No. The quote builder works 100% in your browser. Your business data (name, CIF, address, logo, email, phone) is saved in the localStorage of the browser you are using. It is not sent to any Mr Resin or third-party server. If you clear your browser cache or use incognito mode, the data will be lost.
Yes. In the My business step you can upload your logo (PNG, JPG or WebP up to 500 KB). The logo is saved in localStorage as base64 and appears in the top left corner of the generated PDF. It is scaled proportionally to avoid distortion, with a maximum size of 40×20 mm in the PDF.
A quote is not legally binding on its own until the client accepts it in writing. The Mr Resin quote builder generates a professional document with all the necessary details (breakdown, date, validity, VAT), but it does not replace an invoice. Once the client accepts and the work is carried out, you must issue a separate invoice if you are self-employed or running a business. Consult a tax advisor if you have any questions about invoicing.
Yes. From the 3D resin cost calculator and the filament cost calculator, after calculating the cost of a part, you can click Send to quote builder. This opens the quote builder with the part already pre-filled: description, technology (FDM or Resin), material, quantity and unit cost. You just need to adjust the margin and add any additional parts.
Recommended margins for 3D printing in Spain 2026 are: ×1.5 for hobbyists printing for friends, ×2.5 for semi-professionals selling regularly on Wallapop or Etsy, and ×4 for professional businesses with premises, invoicing and VAT. The default margin in the quote builder is 150% (×2.5). Edit it per line according to the value of the work: parts with a lot of post-processing justify higher margins.
If you invoice regularly and your income exceeds certain thresholds (rules vary by country), yes. As a self-employed person / sole trader, you may need to apply VAT (21% in Spain; rates vary by country) and file quarterly VAT returns (form varies by country). The quote builder includes a toggle to include or exclude VAT: if you are self-employed with 3D printing activity, keep it enabled. If you are below the threshold and your activity is occasional, you may disable it but mention this in the notes. Consult a tax advisor for your specific situation.
Yes, the quote builder is responsive and works on mobile, tablet or desktop. The experience is more comfortable on desktop due to the line items table, but on mobile you can perfectly generate a complete quote with horizontal scrolling in the table. The PDF downloads the same way on Android and iOS.
