Designing for the Future with 3D Printing and Prototyping

Assignments related to 3D printing and prototyping often involve designing mechanical components, enclosures, or assemblies that can be produced using additive manufacturing technologies. For instance, the Raise3D system emphasizes precision, surface finish, and functional prototyping, which are crucial learning points for students.

Before you begin modeling in SolidWorks, ask yourself the following questions:

• What is the purpose of the model — visual prototype, functional part, or concept demonstration?
• What are the dimensional and tolerance requirements?
• What material and 3D printer type are assumed in the assignment (e.g., FDM, SLA, or SLS)?
• Are there restrictions on support structure, overhangs, or print bed size?

Understanding these details helps you create a design that aligns with both SolidWorks modeling standards and 3D printing constraints.

Translating Design Requirements into SolidWorks

Once you understand the design brief, start translating it into 3D geometry using SolidWorks. Let’s outline a structured workflow suitable for most 3D printing-related assignments.

Step 1: Sketching and Conceptualization

Begin by sketching the 2D profiles that define your part geometry. Keep sketches fully defined — this ensures your model remains stable during feature modifications.

• Use reference dimensions and geometric relations (parallel, coincident, symmetric).
• Avoid redundant constraints that can cause rebuild errors.

Step 2: Extruding and Revolving Features

For parts like printer components, mechanical housings, or nozzles, Extruded Boss/Base and Revolved Boss/Base are common features. Keep extrusion directions aligned with your intended print orientation — this minimizes support material during printing.

Step 3: Applying Fillets and Chamfers

Fillets and chamfers not only improve aesthetics but also enhance print quality by reducing sharp edges that may peel during printing. Always apply functional fillets before cosmetic ones.

Step 4: Building Assemblies

Assignments often involve assembling multiple components — similar to Raise3D’s modular printer structure.

Use:

• Mate constraints (coincident, concentric, parallel) to define part relations.
• Exploded views to demonstrate how parts fit together.
• Interference detection to identify overlaps before printing.

Preparing Models for 3D Printing

After completing your model, the next crucial step is exporting it for 3D printing. This is where many students lose marks in assignments — not because of poor design, but due to poor print preparation.

Step 1: Checking Model Integrity

Use SolidWorks’ Evaluate Tab → Check tool to ensure your model has:

• No open surfaces (non-manifold geometry)
• Proper face orientation (normals facing outward)
• Watertight solids (essential for STL export)

Step 2: Scaling and Unit Verification

3D printers interpret models based on units. Always verify your model’s scale in millimeters (mm) — mismatches can lead to distorted prints.

Step 3: Exporting STL Files

Save the file as .STL using:

File → Save As → STL (*.stl)

Then, in Options, set:

• Resolution: Fine
• Output: Binary
• Deviation: ≤ 0.01 mm for detailed parts

This ensures high fidelity in 3D prints, much like Raise3D printers achieve through their ultra-precise extrusion systems.

Step 4: Slicing for Print

Use slicing software like Raise3D ideaMaker, Ultimaker Cura, or PrusaSlicer:

• Adjust infill density (20–100% based on part function)
• Set layer height (0.1–0.3 mm for FDM)
• Use supports strategically for overhangs above 45°

This step bridges your SolidWorks model to physical reality — an essential part of any 3D printing assignment.

Key SolidWorks Tools Useful for 3D Printing Assignments

Assignments inspired by industrial printers like Raise3D require you to go beyond basic modeling. Here are advanced SolidWorks tools to consider:

1. Shell Tool

To reduce print material, hollow out parts while maintaining structural strength. Adjust wall thickness according to the 3D printer’s nozzle size.

2. Draft and Undercut Analysis

Use Draft Analysis to evaluate surfaces that might cause print failures. Positive drafts ease print layering, especially for parts printed vertically.

3. Split and Combine

For large assemblies exceeding the printer’s build volume, Split your model into smaller sections. Later, Combine them post-print for assembly demonstration.

4. Interference Detection

Before finalizing, ensure no two parts overlap. This prevents unnecessary reprints and wasted filament.

5. Section Views

Use section views to demonstrate internal design — a common requirement in SolidWorks assignments where internal mechanisms are graded.

Realistic Simulation for Functional Validation

Modern assignments often require simulating part performance before printing. SolidWorks offers built-in simulation tools for this.

• Static Simulation: Check stress distribution and deformation.
• Thermal Analysis: Evaluate heat resistance for parts like nozzles or extruder heads.
• Motion Simulation: Validate mechanical linkages in assemblies (e.g., Raise3D’s motion gantry).

By including these analyses, your assignment demonstrates not only design skills but also engineering validation — a criterion professors often emphasize.

Common Mistakes Students Make

While solving SolidWorks 3D printing assignments, students frequently encounter the following pitfalls:

Avoiding these mistakes ensures your submission meets both academic and practical standards.

Presenting Your Assignment Professionally

In SolidWorks-related coursework, presentation quality often influences grading.

Here’s how to make your submission stand out:

• Exploded Views: Demonstrate how components assemble or disassemble.
• Bill of Materials (BOM): Include part names, materials, and quantities.
• Detailed Drawings: Provide orthographic and isometric views with dimensioning.
• Rendered Images: Use SolidWorks Visualize or PhotoView 360 to produce photorealistic renders.

Remember, the Raise3D example in your study material emphasizes professional presentation and precision — apply the same to your academic work.

Case Reflection: From Raise3D to Your Project

The Raise3D Printers project highlights innovation through precision and iterative prototyping. When completing your SolidWorks assignment:

• Think like an engineer, not just a designer.
• Validate every design decision with manufacturability in mind.
• Demonstrate how your model can transition from CAD to an actual printed prototype.

This mindset transforms your assignment into a mini engineering project — something that distinguishes excellent submissions from average ones.
