In this step-by-step guide we willwalk you through the process of creating a 3d printed object from start to finish. In our example we used a Revopoint mini 3D scanner, Blender 3d modeling software to optimize the surface, the Repetier and Cura software to position, slice and print on the Geeetech A20T multicolor FDM 3d printer.

Step 1. Find an object you like

For this example, we selected a small statue. The 3D scanner will be able to digitize the part and capture the smallest details in the original part. During the scanning process, the surface and shape of the object is translated into millions of points that have XYZ coordinates, or 3D coordinates. The more precise your scanner (or the higher the resolution), the more details the scanner will be able to capture, hence a more detailed scan will be. It will also create more data, will take longer to process and take up more space on your computer drive.

Step 2. Prepare your object for scanning

At times, if you have translucent shiny objects (like the belly of our buddha statue) you may want to apply a matte product like 3d printing spray or, as an inexpensive alternative, spray chalk as shown in the image below. Using this technique, the scanner will have much better success in reading the surface of the object, ultimately a much better scan.

Step 3. Scan the object

Using a 3D scanner, scan the original object. In our example we used a Revopoint mini scanner and a rotating table. Using the Revo Scan software we were able to scan the object multiple times in different positions to create multiple meshes. Once the scan was completed, we fused them all in a single object in the software.

Step 4. Repair and smooth the object mesh

Using the 3D editing software of your choice, eliminate bumps and imperfections resulted from scanning. For our object, we used Blender, an open source 3D editing and animation software.

Step 5. Inspect the part and export a .STL file

Inspect the surfaces to ensure there are no holes or extra elements. the more precise and smooth the surfaces the better! Generate and export your STL file.

Step 6. Create machine code with your slicer

Import the .STL code in your slicer software to prepare the file for the 3d printing process. In our example, we used the Repetier software. In the software, you can position the part on the plane, select the type of material you will be printing with and the necessary parameters like printing temperature, speed, printing resolution and more.

Slice your object to create machine code for your 3D Printer. Once the slicer is done, ensure everything looks good and you don’t have any collision or strange paths that will create problems during the printing process. Before starting the printing process, heat the printer head/nozzle and the bed (most materials will print better with a heated bed/platform).

Step 7. Print your object

Now sit back, and watch it all happen! You will want to monitor the printer and ensure everything is running smoothly, especially for the first few layers. The first layers are critical because that’s when the filament has the hardest attaching to the base and creating the first layers. Once the first few layers are in place, the filament will adhere much better to each layer creating a nice and smooth surface.

The final result should look like the picture above! For this example, we printed using PLA, a fairly easy material to print at relative low printing temperature but does require a heated bed to ensure the material sticks to the surface and doesn’t get deformed during the cooling process.
