In-house design is cheaper per case only when volume is steady and high. A $3,922 monthly salary alone (BLS median proxy, before benefits and software) equals about 327 full-contour crown units or 140 crown-over-abutment units a month at Dentlyworks' rates. Below that, or with uneven volume, outsourcing usually costs less.
Every lab wrestling with case-load capacity eventually asks the same question: hire an in-house CAD designer, or outsource? The honest answer is that it depends entirely on your volume and how steady it is — but most labs never actually lay out the full cost structure of each option before deciding. Here's what that comparison actually looks like.
The real cost structure of an in-house designer
The salary line is the visible cost, but it's rarely the whole picture. An in-house CAD hire carries several cost categories that exist whether you send them 10 cases or 200 in a given month:
- Software licensing — 3Shape or exocad seat licenses are an ongoing cost independent of case volume.
- Hardware — a workstation capable of running CAD software smoothly, plus periodic refreshes as software requirements grow.
- Ramp-up time — a new designer, even an experienced one, takes time to learn your lab's specific preferences, margin conventions, and QC standards before they're at full speed.
- Time off and turnover — sick days, vacation, and the gap if a designer leaves are all capacity you're paying for but not receiving.
- Benefits and overhead — the fully-loaded cost of an employee is higher than the salary number alone.
None of this makes an in-house hire a bad decision — for a lab with high, steady, predictable volume, these fixed costs get spread across enough cases that the per-case cost can end up lower than outsourcing. The problem is when volume is inconsistent, seasonal, or still growing: you're paying those fixed costs whether or not the case volume shows up to justify them.
The outsourced cost structure
Outsourced CAD design flips the cost structure from fixed to variable. Instead of a monthly cost regardless of volume, you pay per unit or per arch, only for the cases you actually send. Dentlyworks' published rates, for example, run:
- $10-$18 per unit for crown & bridge, depending on case type
- $22-$28 per unit for implant design
- $95-$110 per arch for removable/denture design
- $120-$375 per arch for full-arch/All-on-X design
- $60 per case for digital smile design
There's no salary, no license renewal, no ramp-up period, and no cost during a slow month. The trade-off is that the per-unit rate is higher than what an in-house designer's marginal cost per case would be once they're fully ramped and running at volume — outsourcing is priced to cover the vendor's own fixed costs plus margin, spread across their client base rather than your lab alone.
The core trade-off: in-house trades a higher fixed cost for a lower cost per case at volume. Outsourcing trades a higher cost per case for zero fixed cost and no risk during slow periods.
When each model tends to make more sense
In-house tends to work better when:
- Case volume is high and consistent month to month
- You have the runway to absorb a multi-week ramp-up period
- You want direct, in-person oversight of every case
- You're prepared to manage turnover and coverage gaps yourself
Outsourcing tends to work better when:
- Volume is variable, seasonal, or still growing
- You need capacity now, not after a hiring and training cycle
- You want to test increased volume before committing to a hire
- You occasionally need overflow capacity or coverage for time off
Where the break-even sits
The question that decides this is how many cases you send in a month. As a rough guide, take the U.S. Bureau of Labor Statistics median annual wage of $47,060 (May 2025) for dental and ophthalmic laboratory technicians and medical appliance technicians (BLS Occupational Outlook Handbook). That is about $3,922 a month, and it is a proxy for the broader occupation, not a CAD designer wage. It also excludes benefits, payroll taxes, software and hardware.
Dividing that salary alone by Dentlyworks' published per-unit rates gives the monthly volume at which a salary matches the outsourcing bill:
| Case type | Outsourced rate | Units per month to match a $3,922 salary |
|---|---|---|
| Crown & bridge, coping / simple | $10 / unit | about 392 |
| Crown & bridge, full contour | $12 / unit | about 327 |
| Crown & bridge, veneer / layered | $18 / unit | about 218 |
| Implant, custom abutment | $22 / unit | about 178 |
| Implant, crown over abutment | $28 / unit | about 140 |
Illustrative arithmetic only. Actual designer pay varies by region and experience, and your real costs also include everything below.
Read the table in two directions. If your design volume is well above these numbers every month, an in-house designer is likely cheaper per case. If it is below them, or varies a lot, you are paying for capacity you do not use. Adding benefits, software and hardware lowers the break-even volume, while vacation, sick days and a slow quarter push it back up.
Costs that rarely make it into the spreadsheet
- Idle time. A designer paid for a full month who gets 60% of that in cases still costs 100%.
- Coverage gaps. Time off, illness and turnover leave a hole exactly when volume is high.
- Hiring and training. Posting, interviewing and the ramp-up before a new designer matches your standards all cost time.
- Management time. Someone has to review work, schedule cases and handle quality issues.
- Software and hardware refresh. Seat licences renew and workstations age as file sizes grow.
Five questions to decide
- How many design units do we send in a typical month, and in our slowest month?
- How steady is that number across the year?
- Can we cover time off and turnover without delaying cases?
- Do we need capacity this month, or can we wait for a hiring cycle?
- Would a trial run of outsourced cases tell us more than a spreadsheet?
A hybrid example
Take a lab that sends about 400 design units in a normal month but swings between 300 and 550. Hiring for 550 means idle capacity most of the year. Hiring for 300 and outsourcing the rest means the in-house designer is always busy, and the outsourced share rises and falls with demand. The same split covers vacations and the occasional unusual case. Run your own volumes through the outsourcing cost calculator.
What cost does not capture
Price is only part of the decision. Each model also wins on things a spreadsheet leaves out.
Where an in-house designer wins:
- Immediate, in-person availability. A quick question or a same-hour rush does not need coordinating across an outside relationship.
- Built-in familiarity with your standards. Someone who has worked beside your lab for years absorbs your preferences without needing them written down.
- Full control over hiring, training and culture. You decide exactly who is on the team and how they develop.
Where outsourced design wins:
- Capacity that flexes with volume. No fixed cost sitting idle in a slow week, and no scramble in a busy one.
- Broader system and case-type coverage. A partner handling many labs' cases has likely met more implant systems and case variations than any single hire.
- No hiring risk or ramp-up. Capacity is available now, not after a search and a training period.
Quality is a property of the specific partner, not the category. "In-house is always more consistent" and "outsourcing is always cheaper" are both oversimplifications. What matters is the partner's revision process, and whether your lab's standards are written down where they can follow them.
Three example labs
To see how volume changes the answer, here are three labs that send only full-contour crowns, priced at the $12 per unit rate and compared with the $3,922 monthly salary figure from above:
| Monthly volume | Outsourced at $12 / unit | Salary alone | What it suggests |
|---|---|---|---|
| 100 units | $1,200 | $3,922 | Outsourcing costs about a third as much, and you pay nothing in a slow month |
| 330 units | $3,960 | $3,922 | Roughly break-even on salary, so benefits, software and coverage decide it |
| 500 units | $6,000 | $3,922 | An in-house designer is likely cheaper per case, if volume stays this high |
Illustrative arithmetic on one case type. A real lab has a mix of case types, a mix of complexity and months that are not all alike.
What to track before you decide
A spreadsheet is only as good as its inputs. For 90 days, record the units you design each month by case type, how many hours your current designers spend on design versus corrections, how often cases wait for a designer, and how much work you turned away or delayed for lack of capacity. Those four numbers tell you whether you have a capacity problem or a steady-volume problem, and the answer points to a different solution.
It doesn't have to be all-or-nothing
Plenty of labs run a hybrid model: an in-house designer handles steady baseline volume, and outsourced capacity absorbs overflow, unusual case types, or gaps when the in-house designer is out. This avoids over-hiring for peak volume while still keeping outsourcing costs limited to genuine overflow.
The lowest-risk way to test where the balance sits for your lab is to send a handful of cases to an outsourced vendor and compare the real invoice — turnaround, revision handling, and quality included — against what an equivalent in-house cycle would have cost you in time and fixed overhead. The outsourcing cost calculator is a faster starting point if you want a rough number first.
Common questions
At what volume does hiring an in-house CAD designer become cheaper than outsourcing?
On salary alone, using the BLS median wage of $47,060 for the broader dental laboratory technician group, the break-even is roughly 327 full-contour crowns a month at $12 per unit, or about 218 layered units at $18. Benefits, software and hardware move the break-even lower, and slow months or time off move it higher.
Can I use both an in-house designer and an outsourced partner?
Yes. Many labs keep an in-house designer for steady baseline volume and send overflow, unusual case types and holiday coverage to an outsourced partner.
What is the biggest risk of an in-house hire?
Fixed cost against variable volume. You pay the full cost of the role in every slow month, and you carry the capacity gap when the designer is out or leaves.
