Adapter Design Process¶
We initiated the project by designing the plotter adapter using SolidWorks, which served as my primary contribution to the 3D printer-to-pen plotter conversion. I led the development of the adapter's first component, prioritizing secure mechanical fit and functional reliability. Following my completion of this initial section, Magali progressed the work by designing the subsequent adapter segment, extending the design framework I had established.
3D Printing Configuration¶
Following the design finalization, we proceeded to 3D print the adapter component. Special attention was given to dimensional accuracy to ensure compatibility with our existing setup. The printing process focused on achieving proper layer adhesion and structural integrity to guarantee functional performance during assembly. Post-printing, we verified critical measurements against design specifications before proceeding with system integration.

Structure & Strength ✓ Infill Density: 100% (solid) ✗ Supports: None ✗ Build Plate Adhesion: None
Temperature Settings ✓ Printing Temperature: 0°C (Note: Typically PLA requires 190-220°C) ✓ Build Plate Temperature: 0°C (Note: Typically 50-60°C for PLA)
Advanced Motion ✓ Retraction: Enabled ✓ Z-Hop When Retracted: Enabled ✓ Z-Hop Height: 0.4 mm ✓ Z-axis Scale: 0.2 mm
Machine Assembly Process¶
The machine assembly involved carefully fitting and aligning all mechanical components to ensure proper functionality. Key steps included mounting the structural framework, installing motion systems, and securing the tool attachment mechanism. Precise calibration was critical to maintain alignment and stability throughout the operation. The assembly process required troubleshooting minor fitting issues and verifying each component's integration before proceeding to system testing. This foundational work established the machine's core mechanical functionality.
Hardware Realization & Prototyping¶
During the initial planning session, I discovered that my existing 3D printer already contained all the necessary hardware and electronics for our project. Rather than building a complete machine from scratch, we focused our efforts on two key modifications: developing a pen attachment mechanism and implementing drawing control software.
The solution proved remarkably straightforward. After designing and printing a simple adapter, we successfully transformed the 3D printer into a functional plotter. The entire process - from concept to working prototype - was significantly easier than we had anticipated.
In the following sections, I'll walk you through the exact steps to convert your own 3D printer into a drawing machine, covering both the mechanical adaptation and software configuration needed to bring this project to life.
Step 1: Pen Attachment System¶
To convert your 3D printer into a plotter, you'll need to securely mount a drawing pen to the print head. The key requirements are:
The pen tip must extend slightly below the nozzle (typically 1-2mm) to maintain consistent paper contact
The mounting system must prevent wobbling during movement
My solution uses:
A 3D-printed pen holder adapter
An M3 screw for firm attachment
Adjustable positioning to fine-tune the tip extension
Step 2: System Calibration¶
After securing the pen, precise calibration is essential for accurate plotting. Follow these steps:
Secure the Paper
Use masking tape or clips to firmly attach your drawing paper to the print bed
Ensure full adhesion to prevent shifting during operation
Z-Offset Adjustment
Lower the pen gradually until it makes consistent contact with the paper
The tip should apply enough pressure for clear marks without bending or skipping
Test Patterns
Run simple geometric test patterns (squares, circles)
Verify line consistency and adjust pressure if needed
First-Layer Calibration
Treat this like 3D printing first-layer calibration
Ensure even contact across the entire bed surface
Step 3: Selecting Artwork¶
Use vector (SVG) files for best results. Tip: Add type:svg to Google Image searches to find ready-to-use vector graphics. While image conversion is possible, starting with SVG files simplifies the process.
Step 4: G-Code Conversion¶
The hardware setup proved surprisingly straightforward, but software configuration required more effort. After extensive testing, I developed a reliable workflow to convert designs into plotter-ready G-code.
Key points preserved:
Vector file recommendation
Search tip for SVG files
Hardware/software contrast
Final working solution
Condensed by ~60% while keeping all essential information.
NEXT PROCEEDING WITH MACHINE OPERATION TRIALS¶
Initial Test Plot:¶
During our first test on paper, we encountered an issue where the nozzle was positioned too close to the surface. This caused the extruder to tear the paper during plotting.
Solution:¶
To resolve this, we manually adjusted the nozzle height at the beginning of the print job, ensuring proper clearance for smooth operation.
Plotter Offset Adjustment¶
We discovered that the pen adapter was mounted slightly off-center. To compensate for this, we adjusted the design positioning in the slicing software, shifting it slightly off-center to ensure accurate plotting.
Alternative Version (More Detailed):¶
Identifying the Offset Issue: Since the pen adapter was not perfectly centered, we noticed misalignment in our plots.
Solution Implemented:¶
To correct this, we offset the design coordinates in the slicing software to match the physical displacement of the adapter.
Testing & Results¶
After implementing our adjustments, we saw significant improvements in our plotting results - though we did lose one pen to the testing process!
For our next experiment, we successfully plotted on fabric using standard liner pens (as fabric markers weren't available). The test worked well, and we're excited to try more complex designs in future sessions.
Alternative version with more technical tone:¶
Further Testing Phase
Post-adjustments, we observed:¶
Noticeable improvement in plot quality
One pen casualty during stress testing
We proceeded to fabric plotting using improvised materials (standard liner pens substituting for fabric markers), achieving successful results. This positive outcome has motivated plans for expanded design experimentation.
