Explain each option in the PNG to STL Conversion tool, to effectively create accurate 3D STL model from your PNG images.
Tool
This setting lets you choose how your PNG image is converted into a STL 3D model. You can use "Stander" for a smooth, heightmap-style model based on brightness, or "Stander Color" for a similar effect but with color details. If you want distinct, separate shapes in your model, go for "Extrude", which creates layers, or "Extrude Color", which does the same but keeps different colors as separate elements.
Dimensions and Resolution
Width & Height & Depth: These settings control the overall size of the resulting 3D STL model.
Width Segments & Height Segments: Control the number of subdivisions along the respective axes, affecting the model's resolution and detail. Higher numbers give more detail but make the model more complex.
Border & Border Width
You can add a border around the model for extra structure or visual emphasis. The "Border Width" adjusts how thick that frame is.
Basic Thickness
This value can be adjusted to control how far the STL model extrudes from the base, giving it more dimensionality.
Merges Similar Colors
This helps clean up the model by merging areas with similar colors, making the result smoother and less complex, which is especially helpful for low-quality PNG images.
Transparency Conversion
This lets you decide what happens with transparent areas in your PNG image—either converting them to black or white in the model.
Lock Aspect Ratio
If you want to keep the proportions of your image intact while resizing, this option ensures that the width and height scale together.
Invert Output
This option flips the brightness in the image, turning black into white and vice versa, so the model will be the opposite of the original.
Enable Smoothing
When enabled, this reduces sharp, jagged areas in the 3D geometry of the generated STL model, smoothing out harsh edges.
Z-axis reflector mirror
With this option enabled, the tool mirrors the model along the Z-axis, creating a symmetrical design if needed.
关于将PNG转换为STL的常见问题
如何将我的 PNG 文件转换为 STL ？
首先点击“上传文件”按钮，选择需要转换格式的 PNG 文件。设定相关属性以及目标格式选择 STL ，点击“转换”按钮。转换完成后即可下载您的 STL 文件。将我的 PNG 转换为 STL 需要多长时间？
从 PNG 格式到 STL 格式的转换，通常需要5秒左右。但对于更复杂的文件，可能需要更多的时间，请耐心等待。PNG 到 STL 的转换有多准确？
我们希望能创造出最准确的3D转化器。开发工作持续不断，保持每周推出新功能的节奏，以满足用户更多的需求。在 3dpea.com 上将我的 PNG 文件转换为 STL 是否安全？
非常安全，我们不会存储您上传的文件，下载链接也会在当前网页刷新或者当前浏览器应用关闭后失效。我可以在 Linux、Android、iOS 或 Mac OS 上将 PNG 转换为 STL 吗？
可以。3DPEA文件转换工具可以在任何带有现代网络的系统上运行，在线使用，不需要下载安装任何专业的软件。How does the conversion process work when transforming a PNG image into a STL 3D model?
Our PNG converter uses pixel data from your PNG file to create a height map for the 3D model. Each pixel’s brightness value is interpreted as a height value in the STL or other 3D model file such as 3MF. This way, you can turn your image into a 3D printable model quickly and easily with just a few clicks.What is the purpose of converting PNG files to STL for 3D printing?
Converting a PNG file into an STL format allows you to bring your 2D designs into the 3D world. This is ideal for creating personalized 3D objects, such as logos, custom designs, or even 3D models for prototypes and manufacturing.How do I edit the STL file after converting my PNG image?
Once you’ve converted your PNG file to an STL file, you can further edit the model using 3D modeling software like Blender, MeshLab, or TinkerCAD. These tools allow you to adjust, refine, or enhance your STL file before 3D printing. You can also click the "Create" button in the top right corner to import your STL file for further editing. Once published, you can share it across various social media platforms.Are there any alternatives to using PNG images for creating STL files?
Yes, our converter also supports other image formats, such as JPG, AVIF, and WEBP, to create STL files. If you're interested in converting JPG or SVG files, you can visit our JPG to STL and SVG to STL guides for more detailed instructions.Can I convert multiple PNG images to STL files at once?
Currently, our tool supports converting one PNG file at a time to an STL model. For batch processing, consider using offline batch conversion tools such as ConvUtils.Other PNG Convertsion Tools
