Fill It Right! Your Density Decoder

Strength Inside: Infill Made Easy
Infill density determines how solid your printed object will be inside. It affects weight, strength, material usage, and print time. Below is a complete guide from 5% to 100%.

Infill %	Best For	Description	Strength	Material Use	Print Speed
5%	Display models, prototypes	Ultra-light, hollow core	Very Low	Minimal	Very Fast
10%	Visual items, light props	Lightweight, weak structure	Very Low	Low	Fast
15%	Figurines, showpieces	Better surface support, low strength	Low	Low	Fast
20%	Standard use, general parts	Good balance for everyday prints	Medium	Medium	Average
25%	Light load-bearing parts	Enhanced internal strength	Medium	Medium	Average
30%	Props, enclosures	Suitable for some functional use	Medium	Moderate	Slower
35%	Housings, light tools	Increased strength, stability	Moderate	Moderate	Slower
40%	Moving parts, hinges	Strong and resilient	High	High	Slow
50%	Fixtures, testing jigs	Structurally sound, durable	High	High	Slow
60%	Tough prototypes	Handles stress and drops	Very High	High	Very Slow
70%	Engineering parts	Dense and sturdy	Very High	Heavy	Very Slow
80%	Industrial prototypes	Near-solid interior	Max Strength	Heavy	Long Prints
90%	Rugged use cases	Only slight air gaps	Max Strength	Very Heavy	Very Long
100%	Mechanical & functional end-use	Completely solid print	Maximum	Maximum	Longest

Quick Tips for Customers

• 15–30%: Best for everyday prints with decent strength.
• 40–60%: Recommended for mechanical parts or functional prototypes.
• 70–100%: Use only when strength is critical — heavier, slower, more costly.
