The Mars colony should be self-supporting to the maximum extent possible, relying on a minimum mass of imports from Earth.  Making all the things that 1,000 people will need will require augmenting both the amount and diversity of available labor power through the use of robots and artificial intelligence.  To produce essential bulk materials like food, fabrics, steel, glass, and plastics on Mars, and fabricate them into useful structures, 3-D printing and other advanced fabrication technologies will be essential.

The goal is to have the colony be able to produce all the food, clothing, shelter, power, common consumer products, vehicles, and machines for 1,000 people with only the minimum number of key components, such as advanced electronics needing to be imported from Earth.

Some imports may always be necessary, so useful exports of either material or intellectual products that the colony could produce and transport or transit back to Earth to pay for the imports. In the future, it can be expected that the cost of shipping goods from Earth to Mars will be $500/kg and the cost of shipping goods from Mars to Earth will be $200/kg. These assumptions can guide the designs of economic trade between Earth and Mars to show that after a certain initial investment in time and money that it can become successful.
Some key features to consider when designing a colony on Mars are many fold:

                         Technical design: What systems will be used? How will they work?
                         Economic: How can the colony be made economically successful?
                         Social/Cultural: What should Martian society be like? What kinds of schools, arts, sports, and               
                            other activities, should there be?
                         How, given a fresh start, can life on Mars be made better than life on Earth?
                         Political/organizational: How should the colony govern itself?
                         Aesthetic: How can the colony be made beautiful?

There are many Mars colony designs ranging from initial footprints and flags to permanent habitation (https://www.exploremars.org/wp-content/uploads/2018/08/AM-V-Report_Design_v3.pdf). Each of these require a basic set of capabilities.  Increasing colony size requires ramping up capabilities that allow greater capacity to Live Off the Land (link: https://www.space.com/33563-nasa-mars-colonization-plan.html).  New capabilities can be added in a phased approach leading to less reliance on Earth for many items needed daily by the Mars colony (link: https://arc.aiaa.org/doi/abs/10.2514/6.2015-4479), and some capabilities can be tested at the Moon before committing them to Mars as their maiden voyage.

By the time a colony reaches a population of 1000, many growing pains will fade, resulting in a thriving colony, like the one where Dorothy lives.  This 20-page report describes many of the capabilities needed for a large thriving colony on Mars, mentioning many new technologies while suggesting many opportunities for new research.  Click on the link above to purchase a download of  Dorothy's Long Day at Twin Planitias -
