Materials and Process Development for Additive Manufacturing

Developing the Right Material, Process, and Workflow for Real Parts

JaegerTech provides materials and process development support for companies, universities, foundries, product developers, manufacturers, and research teams that need more than a printed part. We help customers determine what material, print process, settings, finishing method, and production workflow are most appropriate for the application.

In additive manufacturing, success is rarely just about having the right machine. A part may print successfully once and still fail in actual use. It may warp, crack, absorb moisture, soften under heat, abrade too quickly, fail during assembly, bond poorly, or create problems in a downstream process such as coating, molding, casting, or inspection.

Materials and process development is about finding a practical, repeatable way to make the part work.

More Than Material Selection

Choosing a material is only the beginning. The same polymer can behave very differently depending on printer type, nozzle size, layer height, chamber temperature, print orientation, wall count, infill strategy, support method, drying procedure, surface preparation, and post-processing.

JaegerTech helps customers evaluate the full process, including:

  • Material selection
  • Print process selection
  • Print orientation
  • Support strategy
  • Wall, shell, and infill structure
  • Layer height and nozzle size
  • Bed adhesion strategy
  • Moisture control and material drying
  • Dimensional accuracy
  • Surface finish
  • Bonding and assembly
  • Coating and sealing
  • Heat, chemical, and environmental exposure
  • Production repeatability
  • Cost and lead time

The goal is not simply to print a part. The goal is to develop a practical process that produces usable results.

Why Materials and Process Development Matters

A prototype material may not be suitable for the final application. A production material may be difficult to print. A high-strength polymer may require special drying, bed adhesion, chamber heat, or print orientation. A casting pattern material may print well but fail during burnout. A fixture material may work in the shop for a week but deform after months of use.

Materials and process development helps answer important questions early:

  • What material is appropriate for the environment?
  • Can the part be printed reliably?
  • Will it hold tolerance?
  • Will it survive handling or assembly?
  • Does it need to be sealed, coated, or reinforced?
  • Can it be produced repeatedly?
  • Does the process make economic sense?
  • Should the design change to better fit the material?
  • Should the part be printed, machined, cast, molded, or produced another way?

These questions are often cheaper to answer during development than after production has started.

Additive Manufacturing Material Development

JaegerTech works with a broad range of additive manufacturing materials, from common prototyping plastics to engineering-grade polymers and specialty materials.

Depending on the application, materials may include:

  • PLA and PLA-based materials
  • PETG and PCTG
  • ABS and ASA
  • Nylon and nylon-based materials
  • Carbon-fiber-filled polymers
  • Glass-fiber-filled polymers
  • Polycarbonate and PC blends
  • Flexible and semi-flexible materials
  • Resin materials for detailed parts
  • Patternmaking and casting-related materials
  • High-temperature and engineering polymers
  • Specialty materials for tooling, fixtures, or production support

Each material has strengths and limitations. A material that is easy to print may not be strong enough. A material that is strong may be difficult to process. A material that works for a prototype may not be suitable for heat, chemicals, abrasion, sunlight, load, or long-term use.

JaegerTech helps customers make material choices based on the actual job, not just marketing claims or datasheets.

Process Development for Repeatable Results

A successful additive manufacturing process should be repeatable. One good print is useful, but repeatability is what makes the process valuable for production, research, tooling, and customer-facing work.

JaegerTech can help develop print processes around:

  • Machine selection
  • Material preparation
  • Slicer settings
  • Print orientation
  • Support structure
  • Part splitting
  • Assembly strategy
  • Print farm workflow
  • Post-processing steps
  • Inspection and quality checks
  • Documentation
  • Production scheduling

For short-run production, bridge production, or recurring customer work, process consistency matters. A part should not depend on luck, guesswork, or one operator remembering undocumented settings.

Large-Format Process Development

Large-format 3D printing introduces additional process challenges. Big parts do not behave like small parts. Longer print times, larger thermal gradients, material shrinkage, bed adhesion, support removal, and handling all become more important.

JaegerTech can help evaluate large-format process issues such as:

  • Warping over long spans
  • Print orientation for strength and surface finish
  • Sectioning large parts into manageable assemblies
  • Bonding and alignment of printed sections
  • Surface finishing and coating
  • Print time and machine utilization
  • Material cost and failure risk
  • Handling, shipping, and installation

A large part may physically fit on a machine, but that does not always mean it should be printed as one piece. Process development helps determine the lowest-risk path.

Materials for Foundry, Casting, and Patternmaking

JaegerTech has particular experience with additive manufacturing for foundry, casting, and patternmaking applications. These projects require more than dimensional accuracy. The material must also work with the casting workflow.

For sand casting, investment casting, and ceramic shell applications, process questions may include:

  • Will the pattern hold its shape?
  • Does it need draft?
  • Does the surface need sealing or coating?
  • Will the material survive handling?
  • Can the pattern be repaired or modified?
  • How does the material behave during burnout or meltaway?
  • Will it crack ceramic shells?
  • Does it leave ash or debris?
  • Is steam autoclave or controlled burnout appropriate?
  • Should the part be printed directly or used as a master for a mold?

These are not generic 3D printing questions. They are manufacturing process questions.

JaegerTech helps customers evaluate materials and workflows for investment casting patterns, foundry patterns, ceramic shells, tooling masters, core boxes, mold components, and related casting support.

Burnout, Meltaway, and Ceramic Shell Development

For investment casting, the printed pattern must work with the ceramic shell process. A material that prints cleanly may still be a poor choice if it expands, traps residue, cracks shells, or leaves excessive ash.

JaegerTech can help evaluate pattern materials for:

  • Printability
  • Dimensional accuracy
  • Shell compatibility
  • Steam autoclave behavior
  • Burnout performance
  • Meltaway performance
  • Ash and residue
  • Surface quality
  • Support removal
  • Part splitting and venting

True wax filament can be useful in investment casting, but it can be difficult to print reliably. PLA is easy to print, but it can create ceramic shell cracking risks if the burnout process is not managed carefully. JaegerTech continues to evaluate materials and procedures that improve dimensional accuracy, reduce shell cracking, and support cleaner burnout or meltaway results.

Post-Processing and Finishing Development

Many additive manufacturing applications require post-processing. The printed part may need to be sanded, filled, sealed, coated, bonded, primed, painted, drilled, tapped, or fitted with inserts.

JaegerTech can help develop finishing workflows for:

  • Foundry patterns
  • Vacuum forming tools
  • Fixtures and shop aids
  • Appearance models
  • Product prototypes
  • Large-format parts
  • Mold masters
  • Composite layup forms
  • Short-run production parts

Post-processing can affect surface finish, durability, dimensional accuracy, chemical resistance, and downstream usability. A good process considers these steps before printing begins.

Design and Material Must Work Together

A material cannot solve every design problem. Likewise, a good design may fail if paired with the wrong material or print process.

JaegerTech helps customers evaluate the relationship between geometry and material behavior. That may include adjusting:

  • Wall thickness
  • Ribbing
  • Fillets
  • Bosses
  • Fastener locations
  • Insert strategy
  • Split lines
  • Bonding surfaces
  • Support areas
  • Drainage and venting
  • Orientation-sensitive strength
  • Wear surfaces
  • Tolerance zones

In additive manufacturing, design decisions and process decisions are connected. Materials and process development helps align them.

Supporting Research and Experimental Work

Research teams often need custom materials, unusual geometries, specialized fixtures, test articles, or experimental workflows. These projects may not fit standard production methods.

JaegerTech can support research and university teams with:

  • Prototype development
  • Material trial parts
  • Lab fixtures
  • Test coupons
  • Process documentation
  • Equipment setup
  • Research tooling
  • Iterative design support
  • Additive manufacturing workflow development

For academic and research programs, the goal is often not just to make a part. The goal is to learn, validate, compare, and document. JaegerTech can help support that process with practical manufacturing execution.

Supporting Manufacturers and Product Developers

For manufacturers and product developers, materials and process development can help reduce risk before production begins. It can also help solve immediate problems when existing parts, suppliers, or processes are not performing.

JaegerTech can support:

  • Product development
  • Prototype-to-production transition
  • Bridge production
  • Short-run production
  • Tooling and fixture development
  • Manufacturing aids
  • Replacement parts
  • Material substitution
  • Process troubleshooting
  • Cost and lead-time reduction

In many cases, the right development work early prevents expensive redesigns later.

When Additive Manufacturing May Not Be the Right Process

Good materials and process development also means being honest when 3D printing is not the best answer.

Some parts are better machined. Some are better molded. Some are better cast. Some require certified materials, validated processes, or production methods outside additive manufacturing. Some parts can be printed for early testing but should transition to another process for production.

JaegerTech helps customers evaluate these decisions practically.

The goal is not to force every project into additive manufacturing. The goal is to identify the process that best fits the part, quantity, performance requirement, schedule, and budget.

Why Work With JaegerTech

JaegerTech brings hands-on additive manufacturing experience, materials knowledge, foundry and casting support experience, large-format printing capability, and practical manufacturing judgment.

We understand that customers often need more than a part. They need a workable recipe:

  • What material?
  • What machine?
  • What orientation?
  • What settings?
  • What finishing method?
  • What inspection method?
  • What risks?
  • What production path?

Materials and process development helps answer those questions before the project moves too far in the wrong direction.
