Introduction

Selectable topics for presentations are the numeric ones, and alphabetic subitems should be considered as one topic.

Some survey papers to the filed, if presented in the seminar, that will be in the first few weeks:

1. Design Challenges and Opportunities of 3D Printing

Tom Solomon

2. Review of heterogeneous material objects modeling in additive manufacturing

Omer Ben-Hayun

Geometric Challenges

Additive manufacturing poses quite a few new and challenging geometric questions.  Here are a few:

1. a. Generation of patterned indentations for additive manufacturing technologies

b. Geometric Texture Modeling

2. Status, comparison, and future of the representations of additive manufacturing data

3. Embedding Tracking Codes in Additive Manufactured Parts for Product Authentication

Shoham Dahan

4. a. Clever Support: Efficient Support Structure Generation for Digital Fabrication

b. Design of lightweight tree-shaped internal support structures for 3D printed shell models

Bastien Pouëssel

Non layered additive manufacturing

While typically additive manufacturing is happening in layers, printing one planar layer after another, it does not have to be:

1. Five-axis additive manufacturing of freeform models through buildup of transition layers

Rabea Yassin

2. Curved layer based process planning for multi-axis volume printing of freeform parts

3. CurviSlicer: Slightly curved slicing for 3-axis printers

     Daphna Kaplan

4. Trajectory planning for conformal 3d printing using non-planar layers

5. Singularity-Aware Motion Planning for Multi-Axis Additive Manufacturing

6. Volumetric Covering Print-Paths for Additive Manufacturing of 3D Models

Managing Heterogeneity

One of the great benefits one can gain from additive manufacturing is in the ability to 3D print heterogeneous materials.  Different regions in the model will possess different materials and hence present different properties.   Here are some examples:

1. a. Heterogeneous objects representation for Additive Manufacturing: a review

b. Additive manufacturing of functionally graded materials: A review

c. Additive Manufacturing of Functionally Graded Material Objects: A Review

Hihi. Amal

2. A Generalized Optimality Criteria Method for Optimization of Additively Manufactured Multimaterial Lattice Structures

3. Representation of Graded Materials and Structures to Support Tolerance Specification for Additive manufacturing Application

4. a. Additive manufacturing of carbon fiber reinforced thermoplastic composites using fused deposition modeling

b. Load-dependent path planning method for 3D printing of continuous fiber reinforced plastics

c. https://markforged.com/resources/learn/design-for-additive-manufacturing-plastics-composites/3d-printing-strategies-for-composites/fiber-reinforcement-strategies

5. a. Adaptive direct slicing of volumetric attribute data represented by trivariate B-spline functions

b. Fabricating Functionally Graded Material Objects Using Trimmed Trivariate Volumetric Representations

Microstructures and Porosity

Porosity exists in nature in abundance (e.ge bones).  Yet, before the era of 3D printing, the creation of artificial porous geometries was next to impossible.  Here, and with the aid of AM, the world of microstructures and porous geometries is made feasible:

1. Computational discovery of extremal microstructure families

Pierre Khamis

2. Design and fabrication of periodic lattice-based cellular structures

3. Design and Optimization of Conforming Lattice Structures

4. Elastic Textures for Additive Fabrication

5. Optimizing Micro-Tiles in Micro-Structures as a Design Paradigm

Auxetic materials and Compliant Mechanisms

Normal materials when pressed in one direction, expand in others, aiming to preserve volume. Auxetic materials have special behavior in which if compressed in one direction, the material shrinks in the other directions.  These materials are typically some form of microstructures.

Examples of relevant papers are:

1. Auxetic Cellular Materials - a Review

Shir Rorberg

2. A numerical study of auxetic composite panels under blast loadings

3. Design of manufacturable 3D extremal elastic microstructure

4. Auxetic oesophageal stents: structure and mechanical properties

5. 3D printing of twisting and rotational bistable structures with tuning elements

Bar Tzipori

6. Heterogeneous Conforming Compliant Microstructure Mechanisms

Noga Keren

Bio-Printing

Additive manufacturing is gaining a primary seat also in biology.  Here are a few examples from the world of Bio-printing:

1. Design and Fabrication of a Thin-Walled Free-Form Scaffold on the Basis of Medical Image Data and a 3D Printed Template: Its Potential Use in Bile Duct Regeneration

Nitzan Hindin

2. Essential steps in bioprinting: From pre- to post-bioprinting

3. 3-D bioprinting technologies in tissue engineering and regenerative medicine: Current and future trends. 

Adi Rivkin

4. Challenges and Opportunities in Geometric Modeling of Complex Bio-Inspired Three-Dimensional Objects Designed for Additive Manufacturing

Orad Barel

Other applications

One can find new application in areas that are hardly imaginable:

1. a. Exploring Mechanical Meta-Material Structures through Personalised Shoe Sole Design

b. Design of shoe soles using lattice structures fabricated by additive manufacturing

Emma Attal

2. Design of Porous Medium Burners by Means of Additive Manufacturing

3. The Boom in 3D-Printed Sensor Technology

4. a. Biomimetic gyroid nanostructures exceeding their natural origins

b. Design, fabrication, and evaluation of functionally graded triply periodic minimal surface structures fabricated by 3D printing.

5. Material driven design for a chocolate pavilion

The Future of AM

Here are a few publications trying to look into the future:

1. a. Additive manufacturing in 2040

b. How 3-D Printers Could Erase a Quarter of Global Trade by 2060
