SolidWorks 3D Printing Assignments Simplified for Engineering Students

Most SolidWorks 3D printing assignments revolve around two key components:

1. Design creation: Developing a 3D model using SolidWorks that meets specific functional and geometric requirements.
2. Material justification: Selecting and justifying the most suitable filament (PLA, ABS, PETG, Nylon, etc.) based on mechanical, thermal, and practical factors.

When you read an assignment like “Choosing the Best 3D Printing Filament,” your goal is not just to model an object—it’s to engineer a design that’s printable and durable with a chosen material.

To begin, carefully identify:

• The purpose of the model (decorative, structural, functional).
• Environmental conditions it will operate in (temperature, load, exposure).
• Printing constraints like layer height, infill, and nozzle size.

Once you know these, you can map your SolidWorks modeling strategy around them.

Start with Conceptual Planning

Before opening SolidWorks, think through your design intent.

• Sketch your idea: Start with rough sketches of the object you’ll model. Define dimensions and key features.
• Understand the printer’s capability: FDM printers have limitations on overhangs, bridging, and support structures. Design with those constraints in mind.
• Decide the material early: Each filament type behaves differently in printing and performance.

For instance:

• PLA prints easily but is brittle.
• ABS is strong but warps.
• PETG balances strength and flexibility.
• Nylon offers superior durability but absorbs moisture.

This early-stage planning ensures your SolidWorks design won’t require unnecessary rework later.

Modeling the 3D Part in SolidWorks

Now comes the practical phase—building your model in SolidWorks. Here’s how to efficiently approach it.

Step 1: Start with a Base Sketch

Use the Front, Top, or Right Plane depending on the dominant shape of your design. Keep sketches simple at first.

Utilize:

• Lines, circles, splines, and constraints (smart dimensions) to maintain geometric accuracy.
• Fully define sketches before moving to features; undefined sketches often lead to build errors.

Step 2: Create the Core Geometry

Use Extrude Boss/Base, Revolve, or Sweep to form the main body. For 3D printing, focus on solid bodies instead of thin surfaces, as printers need volumetric data.

Step 3: Add Design Features

In assignments like the 3D printing filament selection one, features such as holes, fillets, ribs, and cut-outs play a vital role. These not only enhance functionality but also impact printability.

Key features to consider:

• Fillets reduce stress concentration and improve layer adhesion.
• Ribs add strength without increasing weight.
• Chamfers prevent warping at edges.

Step 4: Manage Multiple Bodies

Sometimes, your design may consist of multiple solid bodies (for example, in assemblies or combined parts). Use the Solid Bodies Folder to manage them, and if necessary, apply Boolean operations (Combine, Subtract, or Common) to create interactions between them.

Optimizing the Design for 3D Printing

After modeling, optimize your design for manufacturability—this is where many students lose marks.

1. Check Wall Thickness

Thin walls can lead to weak prints. Use the Thickness Analysis tool under Evaluate → Thickness Analysis to ensure uniformity. Aim for a minimum of 1.5–2 mm for FDM printers unless specified otherwise.

2. Verify Overhangs and Support Requirements

Perform a Draft Analysis to detect overhangs beyond 45°. Such regions may need support structures, increasing print time. Adjust angles or split parts if necessary.

3. Simplify Geometry

Complex geometries may look impressive but can lead to longer print times or print failures. Optimize curves and holes—especially internal features.

4. Export as STL

Finally, convert your model into an STL file:

Go to File → Save As → STL (.stl)*

Under Options, set:

• Resolution: Fine
• Output as: Binary (smaller file size)
• Units: Millimeters

This ensures your design is ready for slicing and printing.

Selecting the Right Filament Material

Assignments like the one you uploaded emphasize the importance of material selection—a crucial engineering decision. Here’s how to systematically justify it in your report or project submission.

Step 1: Define Functional Requirements

What is the model expected to endure? Load, temperature, or environmental exposure?

For example:

• Functional prototypes → ABS, PETG
• Aesthetic or educational models → PLA
• Durable mechanical parts → Nylon, Polycarbonate

Step 2: Compare Material Properties

In SolidWorks, use the Material Database:

• Right-click the part → Edit Material
• Explore Mechanical, Thermal, and Physical properties.

This tool helps you evaluate:

• Tensile strength
• Elastic modulus
• Heat deflection temperature
• Density

Step 3: Evaluate Printability

Even the strongest material is useless if it’s hard to print. Consider:

• PLA: Beginner-friendly, low warping
• ABS: Strong but needs a heated chamber
• PETG: Excellent strength, minimal odor
• Nylon: High strength but moisture-sensitive

Step 4: Balance Performance and Cost

In academic projects, cost efficiency matters. Always mention how your choice achieves a balance between performance, affordability, and sustainability.

Analyzing the Model in SolidWorks

Professors often expect students to justify designs with data. SolidWorks provides built-in analysis tools that can elevate your submission.

Static Stress Analysis

Using SolidWorks Simulation, you can apply loads and constraints to your model to predict deformation and failure points.

This helps in:

• Comparing how PLA vs ABS handles stress
• Demonstrating why your material choice is optimal

Thermal Analysis

If the part operates under heat, use Thermal Study to observe temperature distribution. This adds depth to your filament justification section.

Mass and Volume Analysis

Under Evaluate → Mass Properties, determine the model’s weight and volume. This data links directly to material usage and printing cost estimation.

Preparing Technical Documentation

A well-structured SolidWorks assignment is not just about modeling—it’s about communication.

Include:

• Exploded Views and Section Views to show internal structure.
• Bill of Materials (BOM) if multiple parts are involved.
• 3D annotations and dimensions for clarity.
• Rendering or RealView Graphics to make your model presentation-ready.

You can generate professional drawings using Make Drawing from Part/Assembly and add standard orthographic views (Front, Top, Right, Isometric).

Common Mistakes Students Make

Avoiding small errors can elevate your grade. Here are frequent pitfalls:

Presenting Your Assignment Like a Professional

Once your design and report are ready:

• Combine SolidWorks screenshots, simulation results, and material comparison tables in your report.
• Add a short justification paragraph linking why your selected filament fits the mechanical and practical needs.
• Always include print settings (layer height, infill %, print speed, temperature) — it shows real-world understanding.

For a polished presentation:

• Use consistent fonts and section headings.
• Include references if you cite data from SolidWorks or material datasheets.
• Add your STL preview and final printed photo if available.
