Why Import an SVG Instead of Using the Shape Library?
CutClay’s built-in shape library covers A growing shape library and handles most earring and cookie cutter designs. But sometimes you need something specific: a custom logo, a shape you sketched yourself, a silhouette from a reference image, or a design you already have as a vector file.
That’s where SVG import comes in. Any vector shape you can create or find can become a 3D-printable cutter in a few steps.
SVG import is a Pro feature in CutClay. If you’re not on Pro yet, you can upgrade here or follow along to see if it fits your workflow before committing.
What Makes a Good SVG for a Cutter?
Not every SVG converts cleanly to a cutter. Before you import, your file should meet a few criteria:
Single closed path. The shape should be one continuous outline with no gaps. Open paths (lines that don’t connect back to their start point) won’t produce a closed cutter wall. If your SVG has multiple paths, you’ll need to merge them into one before importing.
No fills or strokes needed. CutClay uses the path outline to generate the cutter wall. Fills, stroke colors, and gradients are ignored. Only the path shape matters.
Reasonable complexity. Very intricate paths with hundreds of anchor points can produce cutter walls that are too thin in places to print reliably. If your design has extreme fine detail, simplify the path before importing — most of that detail will be lost anyway when printed at 2mm wall thickness.
Clean file. Remove any extra layers, hidden elements, or grouped objects. Export as plain SVG (not Inkscape SVG or Illustrator SVG with extra metadata) for the most reliable import.
How to Create an SVG for Import
You have several options depending on where your design lives:
Inkscape (free): Draw your shape using the pen or bezier tool, or trace a reference image using Path > Trace Bitmap. Once you have your outline, select it, go to Path > Object to Path, then File > Save As > Plain SVG.
Adobe Illustrator: Draw or trace your shape, select the path, and export as SVG. In the export dialog, choose SVG 1.1 and uncheck any options that add extra metadata.
Canva: Canva lets you export elements as SVG. If you’ve drawn a custom shape or have a vector element you want to use, select it and download as SVG. Note that Canva SVGs sometimes include extra wrapper elements — open the file in a text editor and check that the path is clean.
Vectorizer tools: If you have a PNG or JPG of a shape you want to turn into a cutter, tools like vectorizer.io or Adobe Express can trace it to SVG automatically. The quality varies, but for simple silhouettes it works well.
Importing Into CutClay: Step by Step
- Open CutClay Studio and make sure you’re logged in with a Pro account.
- In the left panel, click Import SVG.
- Select your SVG file from your device. The shape loads into the 3D preview.
- If the shape looks wrong (inverted, broken, or missing), your SVG likely has an open path or multiple paths. Go back to your vector editor, fix the path, and re-export.
- Once the shape looks correct, adjust your cutter parameters: size, wall thickness, height, and post hole if making earrings.
- Click Export STL and your custom cutter is ready to print.
Fixing Common Import Problems
Shape appears inverted (cutter wall is on the inside): Your path direction is reversed. In Inkscape, select the path and go to Path > Reverse. In Illustrator, use Object > Path > Reverse Path Direction.
Shape looks fragmented or has holes: You have multiple separate paths. In Inkscape, select all paths and use Path > Union to merge them into one. In Illustrator, use Pathfinder > Unite.
Shape imports but has jagged edges: Too many anchor points, or the path has sharp corners where there should be curves. Smooth the path in your vector editor before re-exporting. In Inkscape, try Path > Simplify to reduce anchor point count.
File won’t import at all: Check that your file is saved as plain SVG (not SVGZ, not Inkscape SVG). Open the file in a text editor and confirm it starts with <svg and contains a <path element.
Tips for Better Cutter Results from SVG
Round off sharp corners before importing. Extremely sharp points in SVG paths produce fragile printed tips that snap off after a few uses. A small 0.5-1mm radius on sharp corners dramatically improves cutter durability without changing the visible shape.
Keep the overall size in mind. An SVG designed at A4 scale will import huge. CutClay will show you the imported dimensions and let you rescale, but it’s easier to design your SVG at roughly the final size you want (e.g., 40mm wide for an earring cutter).
Test with a small print first. Before printing a full-size cutter from a new SVG, print a 50% scale version to check that the path converted cleanly and the walls are where you expect them.
What You Can Make With SVG Import
SVG import opens up a completely different category of cutters. Custom monogram earrings with a client’s initials. A cutter shaped like your business logo. Seasonal shapes that aren’t in any library. Character silhouettes for themed cookie sets. Botanical shapes traced from real leaves.
The shape library is the fastest path to a cutter. SVG import is the path to a cutter nobody else has.
