How 3D Printing Services Work

Never used a 3D printing service before? Here's what to expect — from uploading your file to holding the finished part in your hand.

1

💻 Design or Download Your 3D Model

Start with a 3D model file (STL, STEP, OBJ, or 3MF). You can design your own using free software like TinkerCAD, Fusion 360, or Blender — or download ready-made models from Thingiverse, Printables, or MyMiniFactory.

💡 Tip: Most print shops accept STL files. For engineering parts, STEP files preserve more detail and allow the shop to suggest improvements.

🧪 Choose Your Material & Technology

Different projects need different materials. PLA is great for display pieces, PETG for functional parts, resin for high-detail miniatures, and nylon for industrial applications. Your print shop can help recommend the right material.

💡 Tip: Not sure which material? Check our materials guide or ask the shop — most are happy to advise.

💰 Get a Quote

Upload your file to the print shop's website or email it directly. Most shops provide instant or same-day quotes based on material volume, print time, and complexity. Prices typically range from $5 for small parts to $200+ for large or complex prints.

💡 Tip: Pricing factors: material cost, print time, post-processing (sanding, painting), quantity, and turnaround time.
4

✅ Review & Approve

The shop may send you a preview render or suggest modifications for better printability. Common suggestions include adding supports, adjusting wall thickness, or orienting the part for strength. This is normal — it means they care about quality.

💡 Tip: Ask about minimum wall thickness (usually 1–2mm for FDM, 0.5mm for resin) and whether the part needs support structures.

🖨️ Printing & Post-Processing

Your part is printed layer by layer. FDM prints can take 2–24 hours depending on size. Resin prints are faster for small parts. After printing, the shop removes supports, sands surfaces, and may apply finishing like vapor smoothing or painting.

💡 Tip: Turnaround times vary: same-day for simple parts, 3–7 business days for complex or large orders.
6

📦 Delivery or Pickup

Local shops often offer same-day or next-day pickup. Online services ship nationally — most use USPS, UPS, or FedEx. Expect 2–5 business days for standard shipping, or pay extra for rush delivery.

💡 Tip: Local pickup saves shipping costs. Use our directory to find shops near you.

Frequently Asked Questions

How much does 3D printing cost?

Small parts (keychains, phone stands) typically cost $5–20. Medium parts (enclosures, brackets) run $20–80. Large or complex prints can be $100–500+. Most shops offer instant quotes.

How long does 3D printing take?

Print time depends on size and complexity. A small figurine might take 2–4 hours; a large functional part could take 12–24 hours. Add 1–3 days for post-processing and shipping.

What file format do I need?

STL is the most universal format. STEP files are preferred for engineering parts. OBJ and 3MF are also widely accepted. Most free design tools export to STL.

Is 3D printed stuff strong?

It depends on the material and settings. PLA is suitable for display pieces. PETG and ABS are used in functional parts. Nylon and carbon fiber composites rival injection-molded strength.

Can I get food-safe 3D prints?

Yes, with the right material (food-safe PETG) and post-processing (food-safe coating). Discuss this with your print shop — they can recommend the right approach.

Do I need to know CAD to use a 3D printing service?

No! Many shops accept descriptions or sketches and can model the part for you (for an additional fee). You can also download thousands of free models from sites like Thingiverse.
