Astrength

Bbrand

Ccolor

Dweight

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing color as the main criterion instead of mechanical properties.

Focusing on brand rather than material properties.

Strength is a crucial factor because the material must withstand the intended use conditions.

2fill in blank

medium

Complete the sentence to explain why thermal properties matter in material selection.

3D Printing

Thermal [1] affects how a material behaves during the printing process.

Drag options to blanks, or click blank then click option'

Aconductivity

Bstability

Cresistance

Dexpansion

Attempts:

3 left

💡 Hint

Common Mistakes

Confusing thermal conductivity with expansion.

Ignoring thermal effects on the printed object.

Thermal expansion is important because materials expand or contract when heated or cooled, affecting print accuracy.

3fill in blank

hard

Fix the error in the sentence about environmental impact in material choice.

3D Printing

Choosing a material with low [1] helps reduce waste and pollution.

Drag options to blanks, or click blank then click option'

Aenvironmental impact

Bdurability

Ccost

Dweight

Attempts:

3 left

💡 Hint

Common Mistakes

Selecting cost instead of environmental impact.

Confusing durability with environmental concerns.

Environmental impact refers to how the material affects the environment, so choosing low impact materials is better for sustainability.

4fill in blank

hard

Fill both blanks to complete the criteria for material flexibility and cost.

3D Printing

Materials that are [1] allow bending without breaking, and [2] is important for budget control.

Drag options to blanks, or click blank then click option'

Aflexible

Bexpensive

Ccost

Drigid

Attempts:

3 left

💡 Hint

Common Mistakes

Mixing up flexible and rigid.

Confusing cost with expensive.

Flexible materials can bend without breaking, which is useful for certain designs. Cost is always a key factor to keep projects affordable.

5fill in blank

hard

Fill all three blanks to complete the sentence about material properties and printability.

3D Printing

The [1] of a material affects its strength, [2] determines how easily it melts, and [3] influences the surface finish.

Drag options to blanks, or click blank then click option'

Adensity

Bmelting point

Cviscosity

Dcolor

Attempts:

3 left

💡 Hint

Common Mistakes

Confusing color with viscosity.

Mixing melting point and viscosity.

Density relates to strength and weight, melting point affects how the material melts during printing, and viscosity influences how smooth the surface will be.
