Smart design choices can significantly impact 3D printing expenses. This comprehensive guide presents proven Design for Additive Manufacturing (DfAM) strategies that help reduce material consumption, streamline production workflows, and maintain budget constraints without sacrificing output quality.
1. Lightweight
Why it matters: Reduced material consumption translates to lower expenses and accelerated build timelines. How to apply:- Implement lattice structures or gyroid infills in expansive solid regions
- Swap thick solid sections with ribbed geometries to preserve stiffness
- Use topology optimization tools (nTopology, Altair, Fusion) to automatically decrease material while preserving function
2. Hollowing & Drain Holes
Why it matters: Hollow configurations dramatically decrease print duration and material requirements. How to apply:- Shell or hollow substantial parts to 2-3 mm wall thickness (technology-specific constraints apply)
- Incorporate drain apertures for resin/powder extraction (SLA/MJF specific)
- Position apertures for convenient accessibility throughout post-processing
3. Orientation Optimization
Why it matters: Print orientation impacts support material requirements, surface quality, and production duration. Switching to lower resolution or lower quality material while optimizing orientation can yield significant improvements. How to apply:- Position components to reduce overhangs and decrease support necessity
- Orient elongated, narrow characteristics vertically to conserve XY footprint
- Fine-tune critical surface finishes by facing them upward or at angles
4. Material Selection Based on Application
Why it matters: Premium materials frequently add significant expense. How to apply:- Choose Standard Resin rather than engineering resins unless particular material characteristics are required
- Select "Tech's Choice" options for FDM/SLA materials rather than specific colors to reduce expenses
5. Order in Batches
Why it matters: Build optimization occurs when dispatching substantial quantities of identical components. How to apply:- Request component quantities exceeding 100 for bulk reductions
- Place even larger orders to unlock maximum volume discounts
- Synchronize team scheduling to consolidate requests
6. Choose a More Flexible Deadline
Why it matters: Expedited assignments occupy production capacity. Adaptable schedules enable intelligent batching. How to apply:- Select standard or extended delivery windows at checkout
- Communicate deadline flexibility — we'll batch intelligently
- Reserve expedited services exclusively for components requiring it
7. Design with Material Efficiency in Mind
How it saves you money: Material preference and volume directly influence pricing. DfAM Principles:- Prevent oversized hollow bodies — shell/hollow components with a 2-3 mm wall wherever feasible (technology-specific constraints apply)
- Construct lightweight internal characteristics only when structurally essential
- When complete strength isn't necessary, request a lower-cost material substitute (for example, PA12 or PLA)
8. Minimize Overall Volume
How it saves you money: Material preference and volume directly influence pricing. DfAM Principles:- Fragment prototypes into practical regions — only manufacture the section being examined
- Eliminate non-essential features or visual elements in initial prototyping phases
- If printing a substantial component, contemplate fragmenting and bonding to accommodate smaller, economical build zones
9. Design Around Lead Time, Not Against It
How it saves you money: Flexible delivery dates grant us opportunity to enhance machine allocation. DfAM Principles:- When delivery isn't time-sensitive, choose standard or extended production windows
- Allow your CAD to establish priority — not inner pressure. When design isn't finalized, postpone
- Employ quick-printing options (PLA, PA12) for preliminary evaluation and preserve premium materials for subsequent phases
Summary: Smart DfAM = Real Cost Savings
| Design Move | Cost Impact | DfAM Tip |
|---|---|---|
| Shell the part | Lower Volume | 2-3 mm wall is typically adequate |
| Choose different materials | Lower Raw materials cost | Consult us — we'll recommend the most economical material for your requirements |
| Batch parts | Less processing time per part | We focus on substantial quantities of a single component (no mixed variants or combinations) |
| Opt for longer lead times | Avoid rush fees | Extended production windows = optimal pricing |
