Install the free STEP Importer extension in Blender 5.1 or newer and open SolidWorks STEP files at their true size. The same file opens in PrusaSlicer, with no meters to millimeters conversion on either end.
Blender OBJ export missing textures? Set Path Mode to Copy, ship the .obj, .mtl and image files together, and avoid the three setups that silently drop a texture. Tested in Blender 4.5.
Skip Blender's 3D-Print Toolbox. Export the STL, let PrusaSlicer repair non-manifold edges and flipped normals, and know when to fix it in Blender instead.
Set Blender's unit scale to 0.001 so one unit is one millimeter, export STLs at scale 1.000, and stop parts arriving in the slicer a thousand times too small.
A parametric planter saucer in Blender Geometry Nodes: eleven inputs for size, corner radius, taper and drain ribs. Free STLs on Printables, .blend on CGTrader.
Typed the exact values and the result still looks wrong? Check scene units. Tutorials use meters; a startup file in inches breaks shaders and geometry nodes.
Animate text appearing left to right in Blender with a material node tree: generated coordinates, a Less Than node, two keyframes and the EEVEE alpha setting.
Make an object see-through in the Blender viewport: open the material's Viewport Display panel, click the color and lower the alpha. Three screenshots.
Make Blender's shader node links straight or curvier: Edit › Preferences › Themes › Node Editor › Noodle Curving. Zero is straight, ten is curviest.
Can't bake a photogrammetry texture onto a low-poly mesh in Blender? Export from Zephyr as OBJ, not FBX. An hour of checking settings came down to file format.
Export a Blender model as GLB and insert it into Word, Excel or PowerPoint with Insert, 3D Models, This Device. Rotate, scale and light it inside the document.
Model a knurled cylinder in Blender 2.8 in six steps: 60-vertex cylinder, 24 loop cuts, un-subdivide, extrude individual faces, scale from individual origins.
Building a parts library in Blender: 57 resistor configurations, 19 color-coded values in three lead shapes, with toggleable labels on one material.
Blender texture painting not working and every search answer is for beginners? Check Local View. Toggling it off with the slash key fixed it instantly.
Turn a string of mesh vertices into a Bezier curve with handles in Blender 2.81: Convert To Curve, Set Spline Type to Bezier, then set the handles to Aligned.
Photogrammetry scans carry their own lighting. Set the Blender viewport to Solid, Flat lighting and Texture color for a natural look and a faster viewport.
Blender 2.81's compositor Denoise node with normal and albedo passes: a clean render at 5 samples in 7 seconds instead of 156 seconds at 150. Setup and results.
Where Auto Merge lives in Blender 2.80 (Active Tool, Options) and 3.1 (Tool Settings toggle) so dragging one vertex onto another joins them automatically.
Blender 2.79 unit settings for 3D printing: inches with unit scale 0.0254 and STL export at 25.4, millimeters at 0.001 and export at 1.0, or meters with export at 1000.
Sculpteo's overview of modeling for 3D printing in Blender: the 3D Printing add-on, common mistakes and a walk-through on a simple cat model.
