File Preparation Guide

Prepare Your Design Files

Good files mean accurate quotes and smooth production. This guide covers everything you need to know to get your designs ready for laser cutting and 3D printing.

Why file preparation matters

Clean, production-ready files reduce back-and-forth and help us give you an accurate quote faster. The more complete your files, the less time we spend requesting corrections — and the sooner we can get started on your project.

1 File Formats

Different projects call for different formats. Here's what we accept and when to use each.

SVG
Laser Cutting

Scalable vector graphics. Ideal for 2D cut/engrave designs. Resizes without quality loss — perfect for precision work.

PDF
Laser + 3D

Print-ready format. Great for proofs and designs combining vector + raster elements. Ensure paths are not flattened.

AI
Laser Cutting

Adobe Illustrator native format. Preserves layer structure and vector paths — preferred for complex designs.

EPS
Laser Cutting

Encapsulated PostScript. Wide compatibility, keeps vector data intact. Good fallback when AI isn't available.

DXF
Laser Cutting

Drawing Exchange Format. AutoCAD-compatible. Use for mechanical parts, interlocking pieces, or precise joinery.

STL
3D Printing

Stereolithography mesh format. The standard for 3D printing. Must be watertight (manifold) with no holes.

PNG / JPG
Engraving

Raster image formats. Use for photo engraving or detailed raster artwork. Resolution of 300 DPI or higher recommended.

2 Vector vs. Raster

Understanding the difference helps you send the right file type for your project — and avoids production issues.

Vector Files

Made of mathematical paths (lines, curves, and shapes). Can be scaled to any size without losing quality. Required for cutting operations.

  • Infinite zoom without pixelation
  • Clean, precise cut lines
  • Required for laser cutting
  • Best for: shapes, text, logos, patterns
Paths, not pixels

Raster Files

Made of pixels (small squares of color). Becomes blurry when enlarged. Used for photo engravings and detailed artwork.

  • Fixed resolution (DPI matters)
  • Looks like a digital photo
  • Fine for engraving, not for cutting
  • Best for: photos, gradients, complex artwork
Pixel grid

3 Laser Cutting Specs

Follow these guidelines to ensure your files are production-ready and we can execute your design exactly as intended.

Minimum Stroke Width

Cut lines should be at least 0.25 pt (0.09 mm). Lines thinner than this may not cut completely through or may get damaged during cutting.

Kerf & Offset

Kerf is the material lost during cutting (~0.15–0.3 mm depending on material and power settings). For interlocking pieces, account for kerf compensation. We can adjust offsets on our end — just note it in your quote request.

Nesting & Efficiency

Group same-material parts together and avoid overlapping cut lines. If you have many identical parts, indicate the quantity — we can nest multiple copies to save material and reduce cost.

Cut vs. Engrave Line Weights

Use distinct stroke colors or layers to separate cut lines from engrave lines. Common convention: red = cut, black = engrave. If using a single color, indicate which elements are cuts vs. engravings in your notes.

Multi-Layer / Color Mapping

Map each color/layer to a specific operation (cut, engrave, score). Include a legend or notes specifying what each color represents. We can match standard colors to specific operations if documented.

4 3D Printing Specs

3D prints have their own set of requirements. Here's what to check before sending your files.

Watertight / Manifold Mesh

Your STL must be fully closed with no holes, gaps, or inverted normals. Non-manifold meshes cause printing failures. Use MeshMixer, Meshmixer, or Netfabb to inspect and repair your mesh before submitting.

Wall Thickness Minimums

Walls must be thick enough to print reliably: PLA: 0.8 mm minimum, PETG: 1.0 mm minimum, ABS: 1.0 mm minimum. Thinner walls risk collapsing during printing.

Tolerance & Clearance

For parts that need to fit together (gears, snap-fits, hinges), plan for 0.2–0.4 mm clearance per interface. Tighter tolerances may require more complex setup or finishing.

Supported Orientations

The way a part sits on the print bed affects strength, surface finish, and support needs. Indicate if you have a preferred orientation — we can orient for best quality or least support.

Fill Style

Let us know if you need solid (100%), sparse/grid, or lightweight infill. Grid is fine for decorative parts; solid is best for functional or load-bearing parts. We default to grid unless specified.

5 Material Quick Reference

Not sure which material fits your project? Here's a quick overview of what we work with and the preferred file formats for each.

Laser Cutting Materials

Material Max Thickness Preferred Format Notes
Wood (Baltic Birch, Walnut) 12 mm SVG, AI, PDF Grain direction affects cut quality. Avoid extremely detailed cuts in thick pieces.
Acrylic (Cast / Extruded) 10 mm SVG, AI, EPS Cast acrylic burns less — cleaner edges. Extruded is more budget-friendly.
Leather 4 mm SVG, AI, DXF Natural variation in thickness. Burnishing and edge finish possible.
Metal (Mild Steel, Stainless) 3 mm DXF, AI Requires higher power — may need more time. Anodized or powder-coated sheets work well.
Paper / Cardstock 2 mm SVG, PDF Great for prototyping and packaging. Score rather than cut for fold lines.

3D Printing Materials

Material Min Wall Thickness Resolution Notes
PLA 0.8 mm 0.2 mm layer height Good for models, prototypes, decorative parts. Not food-safe without post-processing.
PETG 1.0 mm 0.2 mm layer height More durable, slightly more flexible. Better impact resistance than PLA.
ABS 1.0 mm 0.2 mm layer height Higher heat resistance. Requires enclosure for consistent results.
Resin 0.5 mm 0.05 mm layer height Very high detail. Smooth surface finish. Brittle — not for functional parts under stress.

6 Frequently Asked Questions

Yes — if you have a rough sketch, reference images, or even a description of what you're envisioning, we can work with that. We offer design services to help turn your concept into production-ready files. Just note it in your quote request and we'll let you know what we need.
We'll let you know what's needed and give you a chance to fix it before production starts. If you're unable to make the changes, we can often prepare the files for a small design fee — just ask during your quote.
Yes. If you have a concept but need help creating print-ready files, we can handle it. Just describe what you need in the quote form and we'll give you a price for the design work before starting anything.
We rarely have to reject files outright. If there's an issue, we'll contact you with a clear explanation of what needs to change and why. We'll hold your quote while you make corrections — no pressure, no deadline.
Absolutely. Submit the quote form with what you know, and you can send actual files once you've decided to move forward. Reference your quote confirmation number so we can match everything up.
