Solidoodle 4: A Deep Dive into a Classic 3D Printer

The Solidoodle 4. For many entering the 3D printing world in the mid-2010s, the name conjures up memories of tinkering, experimenting, and that first taste of bringing digital designs into the physical realm. The Solidoodle 4 promised an accessible entry point into 3D printing, packaged in a relatively affordable and enclosed metal frame. But how does it hold up under scrutiny years later? Let’s dissect this printer, examine its capabilities, and assess its overall value proposition in today’s landscape, focusing solely on its merits without comparing it to other specific machines.

Solidoodle 4: Specifications

Here’s a breakdown of the Solidoodle 4’s key specifications:

• Print Technology: Fused Deposition Modeling (FDM)

• Layer Resolution: 100-300 microns (0.1 - 0.3 mm)
• Filament Diameter: 1.75 mm
• Print Speed: Up to 70 mm/s (advertised)
• Nozzle Diameter: 0.4 mm (typically)
• Heated Bed: Yes
• Frame: Powder-coated metal
• Connectivity: USB
• Software: Compatible with Repetier-Host, Cura, and other open-source slicers.
• Supported Materials: Primarily PLA, but some users experimented with ABS.
• Power Supply: Internal power supply
• Dimensions: Approximately 13 x 13 x 13 inches (330 x 330 x 330 mm)
• Weight: Around 15 lbs (6.8 kg)

Using the Solidoodle 4: Tips and Tricks

Even though the Solidoodle 4 is considered a simpler machine compared to some modern printers, successful printing requires attention to detail. Here’s a collection of useful tips:

• Bed Leveling: This is crucial. The Solidoodle 4 uses a manual bed leveling system with screws at each corner. Patience and precision are key. Use the “paper test” – adjusting the bed until a piece of paper has slight resistance when pulled between the nozzle and the bed. Re-level frequently, especially after moving the printer.
• Bed Adhesion: PLA generally adheres well to a heated bed. However, using painter’s tape or a thin layer of glue stick can significantly improve adhesion, especially for larger prints or materials prone to warping.
• Temperature Settings: PLA typically prints well between 190-220°C nozzle temperature and 60°C bed temperature. Experiment within this range to find the optimal settings for your specific filament. ABS, if you dare to try it, requires higher temperatures (around 230-250°C nozzle and 90-110°C bed) and an enclosed environment to minimize warping.
• Slicing Software: Cura and Repetier-Host are popular choices for slicing models. Familiarize yourself with the settings in these programs. Adjust print speed, layer height, infill density, and support settings to optimize print quality and strength.
• Filament Management: Store your filament in a dry environment to prevent moisture absorption, which can lead to printing problems. Use silica gel desiccant packs in airtight containers.
• Maintenance: Regularly clean the nozzle to prevent clogs. Keep the X, Y, and Z axes lubricated with a light grease or oil. Check and tighten screws periodically to maintain frame rigidity.

Potential Challenges and Troubleshooting

The Solidoodle 4, like any 3D printer, has its quirks. Here are some common issues and potential solutions:

• Warping: This is more common with ABS. Ensure proper bed adhesion, use a heated enclosure, and avoid drafts. Lowering the print speed can also help.
• Clogging: Use a nozzle cleaning kit to remove debris. Increase the nozzle temperature slightly or try cold pulls to dislodge stubborn clogs.
• Layer Separation: This can be caused by insufficient bed adhesion, low nozzle temperature, or incorrect layer height settings.
• Extruder Problems: Check the extruder motor and drive gear. Ensure the filament is feeding smoothly and the gear is not worn.
• Calibration Issues: If prints are consistently undersized or oversized, check the steps per mm settings in your firmware.

Solidoodle 4 Evaluation (Out of 10)

Here’s a rating of the Solidoodle 4 based on various key aspects, considering its context when it was relevant:

• Print Quality: 6/10 - Acceptable for basic prints, but can struggle with fine details.
• Build Volume: 5/10 - Limited compared to many current printers.
• Printing Speed: 6/10 - Relatively slow, even by the standards of its time.
• Material Compatibility: 5/10 - Best suited for PLA. ABS requires significant tinkering and an enclosure.
• Bed Adhesion & Leveling: 5/10 - Requires manual leveling and careful attention. Bed adhesion can be finicky.
• Reliability: 6/10 - Can be temperamental, requiring frequent adjustments and maintenance.
• Ease of Use: 5/10 - Not the most user-friendly, especially for beginners.
• Firmware and Software: 6/10 - Relies on open-source firmware and software, which requires some technical knowledge.
• Connectivity Options: 4/10 - Limited to USB connectivity.
• Build Quality & Durability: 7/10 - The metal frame provides a solid foundation.
• Noise Level: 6/10 - Moderate noise level during operation.
• Maintenance Requirements: 7/10 - Requires regular cleaning, lubrication, and tightening of screws.
• Customer Support: 3/10 - Solidoodle is no longer operating, so support is limited to online communities and forums.
• Upgradeability: 6/10 - Some upgrade options are available, but limited compared to more modern printers.
• Price to Performance Ratio: 7/10 - At its original price point, it offered a reasonable entry into 3D printing.

Overall Average Score: 5.73 / 10

Conclusion

The Solidoodle 4 represents a significant step in bringing 3D printing to a wider audience. While it has limitations compared to today’s advanced machines, its sturdy build, enclosed frame, and heated bed made it a popular choice for hobbyists and beginners in the past. While support from the manufacturer is nonexistent, the open-source nature of the printer and the existence of online communities can help users troubleshoot and keep their Solidoodle 4 printers running.
